Description
[0001] This non provisional application claims the benefit of
French Application No. 06 51410 filed on Apr. 21, 2006 and U.S.
Provisional Application No. 60/797,670 filed on May 5, 2006.
[0002] The present invention relates to a kit for making up and/or
caring for the eyelashes, comprising at least one cosmetic
composition for making up and/or caring for the eyelashes and at
least one charging cosmetic composition for making up and/or caring
for the eyelashes, comprising a means for applying said charging
cosmetic composition to only a portion of the eyelash fringe, and
in particular at most the outer third of the eyelash fringe.
[0003] There is a need to obtain novel makeup effects on the
eyelashes and especially to deposit mascara more substantially on
only a portion of the eyelash fringe.
[0004] Using an applicator of standard brush or comb type, it may
prove difficult to place a precise deposit of material on only a
portion of the eyelashes, while avoiding the formation of
lumps.
[0005] It may in fact be interesting, in order to obtain particular
makeup effects, to work on deposits of contrasted material on
unconnected areas of the eyelash fringe.
[0006] The inventors have found that by applying a larger amount of
makeup on part of the eyelashes, in particular a large deposit of
material on at most one third of the eyelash fringe, and more
particularly on the outer part of the eyelash fringe, a particular
makeup result is afforded which opens the gaze and enlarges the
eyes, optically modifying the perception of the shape of the eyes.
Such makeup comprising a larger deposit of material on at most a
third of the fringe, on the exterior of the fringe, gives an
impression of almond-shaped and elongated eyes, the outer corner of
which is raised ("lifting" effect on the gaze).
[0007] The invention is thus directed toward a means for easily
achieving this particular makeup objective.
[0008] According to one of its aspects, one subject of the present
invention is thus a kit for making up and/or caring for the
eyelashes, characterized in that it comprises:
[0009] at least one composition (i) with a total content of wax(es)
and of hydrophilic polymer(s) of less than or equal to 26% by
weight relative to the total weight of the composition,
[0010] at least one composition (ii) with a total content of
wax(es) and of hydrophilic film-forming polymer(s) of greater than
26% by weight relative to the total weight of the composition,
at least one of said compositions (i) and (ii) comprising a
continuous aqueous phase, and in that it comprises a means for
applying to the eyelash fringe, comprising a plurality of
application members (6; 60) arranged on a support (5) in the form
of at least one row whose length is such that the application
members (6; 60) can at best simultaneously contact at most a
quarter of the eyelashes of the fringe.
[0011] The inventors have thus observed that the application to the
eyelashes of composition (i) and of composition (ii), at least one
of which is applied using this particular application means, and
more preferentially composition (ii), makes it readily possible to
produce a more volumizing or charging deposit on only part of the
eyelash fringe, for example on at most the outer third of the
eyelash fringe.
[0012] In particular, composition (i) makes it possible to obtain a
smooth, uniform deposit, which is easy to apply, and which coats,
separates and/or lengthens the eyelashes. Composition (i) makes it
possible to obtain sparingly charging makeup, i.e. it does not
thicken the eyelashes: a natural makeup result is thus obtained. It
is thus possible to easily produce, on this first film of makeup, a
more volumizing or charging deposit on only part of the eyelash
fringe, for example on at most the outer third of the eyelash
fringe, by applying composition (ii), which, by virtue of its total
content of waxes and of hydrophilic polymer(s), makes it possible
to obtain a larger deposit of material.
[0013] Thus, this kit makes it possible to accentuate the contrast
between the makeup afforded by the deposit of composition (i) and
that afforded by the deposit of composition (ii), while at the same
time avoiding the formation of "blobs", which are considered
unaesthetic.
[0014] According to a second aspect, the present invention relates
to a process for making up and/or for the non-therapeutic care of
the eyelashes, characterized in that it comprises:
[0015] at least one step of applying to the eyelashes at least one
coat of a composition (i) with a content of wax(es) and of
hydrophilic polymer(s) of less than or equal to 26% by weight
relative to the total weight of the composition, and
[0016] at least one step of applying at least one coat of a
composition (ii) with a total content of wax(es) and of hydrophilic
film-forming polymer(s) of greater than 26% by weight relative to
the total weight of the composition,
at least one of said compositions (i) and (ii) comprising a
continuous aqueous phase, and the step of applying composition (ii)
being performed using the application means comprising a plurality
of application members (6; 60) arranged on a support (5) in the
form of at least one row whose length is such that the application
members (6; 60) can at best simultaneously contact at most a
quarter of the eyelashes of the fringe.
[0017] According to a third aspect, a subject of the present
invention is a made-up support, such as false eyelashes, comprising
a makeup that may be obtained according to the process as defined
above.
[0018] The makeup kits in accordance with the invention comprise a
physiologically acceptable medium, especially a cosmetically
acceptable medium, i.e. a medium that is compatible in particular
with the eyelashes and the area of the eyes.
[0019] The user may obtain the makeup effect by contrasted deposit
of material by means of at least two application actions.
[0020] The order of application of composition (i) and of
composition (ii) can vary. However, it is preferred to apply
composition (i) before composition (ii).
[0021] Depending on the order of application, one or the other of
the cosmetic compositions may be termed a "base coat" or a "top
coat".
[0022] In the context of the present invention, the term
"cosmetically acceptable" means a compound whose use is compatible
with application to the eyelashes.
[0023] For the purposes of the present invention, the term "fringe"
denotes the eyelashes of the upper eyelid or those of the lower
eyelid, from the inner corner to the outer corner of the eyelid, or
the eyebrows of the eyebrow arch of one or other of the user's
eyes.
[0024] The term "comprising one" should be understood as being
synonymous with the expression "comprising at least one", and the
term "between" should be understood as including the limits, unless
otherwise specified.
[0025] All the contents of components are expressed as solids.
[0026] The terms "application means" and "applicator" are used
without preference in the rest of the description.
[0027] The term "composition with an aqueous continuous phase"
means that the composition has a conductivity, measured at
25.degree. C., of greater than 23 .mu.S/cm (microSiemens/cm), the
conductivity being measured, for example, using an MPC227
conductimeter from Mettler Toledo and an Inlab730 conductivity
measuring cell. The measuring cell is immersed in the composition
so as to remove the air bubbles that might be formed between the
two electrodes of the cell. The conductivity reading is taken once
the conductimeter value has stabilized. A mean is determined on at
least three successive measurements.
[0028] According to one preferred embodiment, the two compositions
(i) and (ii) comprise an aqueous continuous phase.
[0029] The compositions (i) in accordance with the invention have a
total content of wax(es) and of hydrophilic polymer(s) of less than
or equal to 26% by weight, preferably less than or equal to 24% by
weight and better still less than or equal to 23.5% by weight
relative to the total weight of the composition.
[0030] They may comprise a total content of wax(es) and of
hydrophilic polymer(s) of greater than or equal to 10% by weight
and preferably greater than or equal to 15% by weight relative to
the total weight of composition (i).
[0031] According to one exemplary embodiment, compositions (ii) in
accordance with the invention, preferably with an aqueous
continuous phase, have a total content of wax(es) and of
hydrophilic polymer(s) of greater than 26% by weight, preferably
greater than or equal to 27% by weight and better still greater
than or equal to 28% by weight relative to the total weight of the
composition.
[0032] They may have a total content of wax(es) and of hydrophilic
polymer(s) ranging up to 50% by weight relative to the total weight
of composition (ii).
[0033] According to one particular embodiment of the invention, the
kit is such that the difference between the total content of
wax(es) and of hydrophilic polymer(s) of composition (ii) and the
total content of wax(es) and of hydrophilic polymer(s) of
composition (i) is greater than or equal to 2%, or even 3%, and
better still 4% as an absolute value.
[0034] Waxes
[0035] For the purposes of the present invention, the term "wax"
means a lipophilic compound, which is solid at room temperature
(25.degree. C.), with a reversible solid/liquid change of state,
which has a melting point of greater than or equal to 30.degree.
C., which may be up to 120.degree. C.
[0036] The melting point of the wax may be measured using a
differential scanning calorimeter (DSC), for example the
calorimeter sold under the name DSC 30 by the company Mettler.
[0037] The waxes may be hydrocarbon-based waxes, fluoro waxes
and/or silicone waxes and may be of plant, mineral, animal and/or
synthetic origin. In particular, the waxes have a melting point of
greater than 25.degree. C. and better still greater than 45.degree.
C.
[0038] The wax may be present in a content ranging from 0.1% to 50%
by weight, better still from 1% to 40% and even better still from
5% to 30% by weight relative to the total weight of each
composition (i) and (ii).
[0039] According to one exemplary embodiment of the invention, the
content of wax(es) in composition (i) ranges from 1% to 40%,
preferably from 5% to 30%, and better still from 8% to 25% by
weight relative to the total weight of the composition.
[0040] According to one exemplary embodiment of the invention, the
content of wax(es) in composition (ii) ranges from 5% to 40%,
preferably from 15% to 30% and better still from 18% to 25% by
weight relative to the total weight of the composition.
[0041] Thus, in a most particularly preferred manner, the kit
comprises a composition (i) with a content of wax(es) of between 8%
and 25% by weight relative to its total weight and a composition
(ii) with a content of wax(es) of between 18% and 25% by weight
relative to its total weight.
[0042] Hydrocarbon-based waxes, for instance beeswax, lanolin wax
or Chinese insect wax; rice wax, carnauba wax, candelilla wax,
ouricury wax, esparto grass wax, cork fiber wax, sugarcane wax,
Japan wax and sumach wax; montan wax, microcrystalline waxes,
paraffins and ozokerite; polyethylene waxes, the waxes obtained by
Fisher-Tropsch synthesis and waxy copolymers, and also esters
thereof, may especially be used.
[0043] Mention may also be made of waxes obtained by catalytic
hydrogenation of animal or plant oils containing linear or branched
C.sub.8-C.sub.32 fatty chains.
[0044] Among these waxes that may especially be mentioned are
hydrogenated jojoba oil, isomerized jojoba oil such as the
trans-isomerized partially hydrogenated jojoba oil manufactured or
sold by the company Desert Whale under the commercial reference
Iso-Jojoba-50.RTM., hydrogenated sunflower oil, hydrogenated castor
oil, hydrogenated coconut oil, hydrogenated lanolin oil and
bis(1,1,1-trimethylolpropane)tetrastearate sold under the name Hest
2T-4S by the company Heterene,
bis(1,1,1-trimethylolpropane)tetrabehenate sold under the name Hest
2T-4B by the company Heterene.
[0045] Mention may also be made of silicone waxes, for instance
alkyl or alkoxy dimethicones containing from 16 to 45 carbon atoms,
and fluoro waxes.
[0046] The wax obtained by hydrogenation of olive oil esterified
with stearyl alcohol, sold under the name Phytowax Olive 18 L57 or
else the waxes obtained by hydrogenation of castor oil esterified
with cetyl alcohol sold under the names Phytowax ricin 16L64 and
22L73 by the company Sophim may also be used. Such waxes are
described in patent application FR-A-2 792 190.
[0047] According to one particular embodiment, the compositions (i)
or (ii) in accordance with the invention may comprise at least one
"tacky" wax, i.e. a wax with a tack of greater than or equal to 0.7
N.s and a hardness of less than or equal to 3.5 MPa.
[0048] The use of a tacky wax may especially allow the production
of a cosmetic composition that is easy to apply to the eyelashes,
that attaches well to the eyelashes and that leads to the formation
of a smooth, uniform and thickening makeup.
[0049] The tacky wax used may especially have a tack ranging from
0.7 N.s to 30 N.s, in particular greater than or equal to 1 N.s,
especially ranging from 1 N.s to 20 N.s, in particular greater than
or equal to 2 N.s, especially ranging from 2 N.s to 10 N.s and in
particular ranging from 2 N.s to 5 N.s.
[0050] The tack of the wax is determined by measuring the change in
force (compression force or stretching force) as a function of
time, at 20.degree. C., using the texturometer sold under the name
TA-TX2i.RTM. by the company Rheo, equipped with a conical acrylic
polymer spindle forming an angle of 45.degree..
[0051] The measuring protocol is as follows:
[0052] The wax is melted at a temperature equal to the melting
point of the wax+10.degree. C. The molten wax is poured into a
container 25 mm in diameter and 20 mm deep. The wax is
recrystallized at room temperature (25.degree. C.) for 24 hours
such that the surface of the wax is flat and smooth, and the wax is
then stored for at least 1 hour at 20.degree. C. before measuring
the tack.
[0053] The texturometer spindle is displaced at a speed of 0.5 mm/s
then penetrates the wax to a penetration depth of 2 mm. When the
spindle has penetrated the wax to a depth of 2 mm, the spindle is
held still for 1 second (corresponding to the relaxation time) and
is then withdrawn at a speed of 0.5 mm/s.
[0054] During the relaxation time, the force (compression force)
decreases greatly until it becomes zero, and then, during the
withdrawal of the spindle, the force (stretching force) becomes
negative and then rises again to the value 0. The tack corresponds
to the integral of the curve of the force as a function of time for
the part of the curve corresponding to negative values of the force
(stretching force). The tack value is expressed in N.s.
[0055] The tacky wax that may be used generally has a hardness of
less than or equal to 3.5 MPa, in particular ranging from 0.01 MPa
to 3.5 MPa, especially ranging from 0.05 MPa to 3 MPa or even
ranging from 0.1 MPa to 2.5 MPa.
[0056] The hardness is measured according to the protocol described
previously.
[0057] A tacky wax that may be used is a C.sub.20-C.sub.40
alkyl(hydroxystearyloxy)stearate (the alkyl group containing from
20 to 40 carbon atoms), alone or as a mixture, in particular a
C.sub.20-C.sub.40 alkyl 12-(12'-hydroxystearyloxy)stearate, of
formula (II):
##STR00001##
[0058] in which m is an integer ranging from 18 to 38, or a mixture
of compounds of formula (II).
[0059] Such a wax is especially sold under the names Kester Wax K
82 P.RTM. and Kester Wax K 80 P.RTM. by the company Koster
Keunen.
[0060] The waxes mentioned above generally have a starting melting
point of less than 45.degree. C.
[0061] The microcrystalline wax sold under the reference SP18 by
the company Strahl & Pitsch, which has a hardness of about 0.46
MPa and a tack value of about 1 N.s, may also be used.
[0062] The wax(es) may be in the form of an aqueous microdispersion
of wax. The expression "aqueous microdispersion of wax" means an
aqueous dispersion of wax particles in which the size of said wax
particles is less than or equal to about 1 .mu.m.
[0063] Wax microdispersions are stable dispersions of colloidal wax
particles, and are described especially in "Microemulsions Theory
and Practice", L. M. Prince Ed., Academic Press (1977) pages
21-32.
[0064] In particular, these wax microdispersions may be obtained by
melting the wax in the presence of a surfactant, and optionally of
a portion of water, followed by gradual addition of hot water with
stirring. The intermediate formation of an emulsion of the
water-in-oil type is observed, followed by a phase inversion, with
final production of a microemulsion of the oil-in-water type. On
cooling, a stable microdispersion of solid wax colloidal particles
is obtained.
[0065] The wax microdispersions may also be obtained by stirring

mean sizes of less than 1 .mu.m (especially ranging from 0.02 .mu.m
to 0.99 .mu.m) and preferably less than 0.5 .mu.m (especially
ranging from 0.06 .mu.m to 0.5 .mu.m).
[0067] These particles consist essentially of a wax or a mixture of
waxes. However, they may comprise a small proportion of oily and/or
pasty fatty additives, a surfactant and/or a common liposoluble
additive/active agent.

may range from 0.01% to 30% by weight, in particular from 0.1% to
25% by weight and better still from 0.1% to 20% by weight relative
to the total weight of the composition.
[0216] Dyestuff
[0217] Each of the compositions (i) or (ii) in accordance with the
invention may also comprise at least one dyestuff, for instance
pulverulent dyes, liposoluble dyes and water-soluble dyes.
[0218] According to one embodiment, compositions (i) and (ii) have
the same shade.
[0219] According to another embodiment, compositions (i) and (ii)
have different shades, so as to reinforce the makeup effect
obtained.
[0220] It is possible, for example, to apply a light-colored
composition to the entire eyelash fringe or an inner portion of the
eyelash fringe, and a darker-colored composition to the outer
portion of the eyelash fringe.
[0221] The pulverulent dyestuffs may be chosen from pigments and
nacres.
[0222] The pigments may be white or colored, mineral and/or
organic, and coated or uncoated. Among the mineral pigments that
may be mentioned are titanium dioxide, optionally surface-treated,
zirconium oxide, zinc oxide or cerium oxide, and also iron oxide or
chromium oxide, manganese violet, ultramarine blue, chromium
hydrate and ferric blue. Among the organic pigments that may be
mentioned are carbon black, pigments of D&C type, and lakes
based on cochineal carmine or on barium, strontium, calcium or

[0223] The nacres may be chosen from white nacreous pigments such
as mica coated with titanium or with bismuth oxychloride, colored
nacreous pigments such as titanium mica with iron oxides, titanium
mica with, especially, ferric blue or chromium oxide, titanium mica
with an organic pigment of the abovementioned type, and also

[0225] These dyestuffs may be present in a content ranging from
0.01% to 30% by weight relative to the total weight of each
composition (i) and (ii).
[0226] Fillers
[0227] Each of the compositions (i) or (ii) in accordance with the
invention may also comprise at least one filler.
[0228] The fillers may be chosen from those that are well known to
those skilled in the art and commonly used in cosmetic
compositions. The fillers may be mineral or organic, and lamellar
or spherical. Mention may be made of talc, mica, silica, kaolin,
polyamide powders, for instance the Nylon.RTM. sold under the trade
name Orgasol.RTM. by the company Atochem, poly-.beta.-alanine
powders and polyethylene powders, powders of tetrafluoro-ethylene
polymers, for instance Teflon.RTM., lauroyllysine, starch, boron

zinc laurate and magnesium myristate.
[0229] It is also possible to use a compound that is capable of
swelling on heating, and especially heat-expandable particles such
as non-expanded microspheres of copolymer of vinylidene
chloride/acrylonitrile/methyl methacrylate or of acrylonitrile
homopolymer copolymer, for instance those sold, respectively, under
the references Expancel.RTM. 820 DU 40 and Expancel.RTM. 007WU by
the company Akzo Nobel.
[0230] The fillers may represent from 0.1% to 25% and in particular
from 1% to 20% by weight relative to the total weight of the
composition.
[0231] Each of the compositions (i) and (ii) in accordance with the
invention may also comprise any additive usually used in cosmetics,
such as antioxidants, preserving agents, fibers, fragrances,
neutralizers, gelling agents, thickeners, vitamins, coalescers and
plasticizers, and mixtures thereof.
[0232] Fibers
[0233] Each of the compositions (i) or (ii) in accordance with the
invention may also comprise fibers that allow an improvement in the
lengthening effect.
[0234] The term "fiber" should be understood as meaning an object
of length L and diameter D such that L is very much greater than D,
D being the diameter of the circle in which the cross section of
the fiber is inscribed. In particular, the ratio L/D (or shape
factor) is chosen in the range from 3.5 to 2500, especially from 5
to 500 and in particular from 5 to 150.
[0235] The fibers that may be used in the composition of the
invention may be mineral or organic fibers of synthetic or natural
origin. They may be short or long, individual or organized, for
example braided, and hollow or solid. They may have any shape, and
may especially have a circular or polygonal (square, hexagonal or
octagonal) cross section, depending on the intended specific
application. In particular, their ends are blunt and/or polished to
prevent injury.
[0236] In particular, the fibers have a length ranging from 1 .mu.m
to 10 mm, preferably from 0.1 mm to 5 mm and better still from 0.3
mm to 3.5 mm. Their cross section may be within a circle of
diameter ranging from 2 nm to 500 .mu.m, preferably ranging from
100 nm to 100 .mu.m and better still from 1 .mu.m to 50 .mu.m. The
weight or yam count of the fibers is often given in denier or
decitex, and represents the weight in grams per 9 km of yam. In
particular, the fibers according to the invention may have a yarn
count chosen in the range from 0.15 to 30 denier and better still
from 0.18 to 18 denier.
[0237] The fibers that may be used in the composition of the
invention may be chosen from rigid or non-rigid fibers, and may be
of synthetic or natural, mineral or organic origin.
[0238] Moreover, the fibers may or may not be surface-treated, may
be coated or uncoated, and may be colored or uncolored.
[0239] As fibers that may be used in the composition according to
the invention, mention may be made of non-rigid fibers such as
polyamide (Nylon.RTM.) fibers or rigid fibers such as
polyimideamide fibers, for instance those sold under the names
Kermel.RTM. and Kermel Tech.RTM. by the company Rhodia or
poly(p-phenyleneterephthalamide) (or aramid) fibers sold especially
under the name Kevlar.RTM. by the company DuPont de Nemours.
[0240] The fibers may be present in the composition according to
the invention in a content ranging from 0.01% to 10% by weight, in
particular from 0.1% to 5% by weight and more particularly from
0.3% to 3% by weight relative to the total weight of the
composition.
[0241] Cosmetic Active Agents
[0242] As cosmetic active agents that may be used in compositions
(i) or (ii) in accordance with the invention, mention may be made
especially of antioxidants, preserving agents, fragrances,
neutralizers, emollients, moisturizers, vitamins and screening
agents, in particular sunscreens.
[0243] Needless to say, a person skilled in the art will take care
to select the optional additional additives and/or the amount
thereof such that the advantageous properties of the composition
according to the invention are not, or are not substantially,
adversely affected by the envisioned addition.
[0244] According to one particular embodiment of the invention:
[0245] composition (i) comprises a continuous aqueous phase, at
least one tacky wax with a tack of greater than or equal to 0.7 N.s
and a hardness of less than or equal to 3.5 MPa, at least the
combination of a cationic hydrophilic polymer and an anionic
hydrophilic polymer and at least one acrylic terpolymer as
described above, and
[0246] composition (ii) comprises a continuous aqueous phase, at
least one tacky wax with a tack of greater than or equal to 0.7 N.s
and a hardness of less than or equal to 3.5 MPa, at least the
combination of a cationic hydrophilic polymer and an anionic
hydrophilic polymer and at least one film-forming polymer dispersed
in an aqueous phase.
[0247] The two compositions (i) and (ii) may also differ in at
least one optical characteristic that is visible to the naked eye,
other than the shade afforded by the presence of dyestuffs. It may
especially be the sheen.
[0248] Kit
[0249] The kit according to the present invention may
advantageously comprise one or more means for applying the cosmetic
compositions (i) and (ii) in accordance with the invention.
[0250] Composition (ii) is applied using the application means
described more particularly hereinbelow.
[0251] Composition (i) may be applied using any brush or any comb
commonly used for making up the eyelashes and/or the eyebrows.
[0252] In the present case, it is particularly advantageous to
apply composition (i) with a makeup brush as described in patents
FR 2 701 198, FR 2 605 505, EP 792 603 and EP 663 161.
[0253] The makeup kit according to the invention may, according to
one particular embodiment, comprise at least two separate
packagings, one comprising composition (i) defined above and the
other comprising composition (ii) also defined above, either one
possibly being, without preference, a "top coat" or "base coat"
composition depending on the order of application, as has been
described hereinabove.
[0254] The kit according to the invention may comprise a wiping
member. This wiping member may comprise, for example, a block of an
alveolar material such as an open-cell or closed-cell foam, with or
without flocking. As a variant, the wiping member may comprise an
optionally flocked, non-alveolar material, for example an elastomer
or a polyolefin. In this case especially, the wiping member may
comprise, for example, at least one slit and/or may comprise a lip
arranged to wipe the stem.
[0255] Since the application of makeup to the eyelashes or the
eyebrows is performed by means of a multiple action by the user,
i.e. in at least two steps, the first consisting in applying the
"base coat" composition and the second consisting in applying the
"top coat" composition totally or partially over said cosmetic
composition, a makeup kit conditioned in one and the same packaging
is particularly suitable. This alternative constitutes a preferred
embodiment of the invention.
[0256] When the kit is in the form of one and the same packaging,
it may be presented as a container delimiting at least one
compartment or reservoir that comprises composition (i), said
compartment being closed by means of a closing member, and at least
one compartment or reservoir that comprises composition (ii), also
being closed by means of a closing member.
[0257] Again, when the kit is in the form of one and the same
packaging, this packaging preferably comprises at least one
application means or applicator for the composition (i), especially
in the form of a brush comprising an arrangement of bristles
maintained by a twisted wire. Such a twisted brush is especially
described in patent U.S. Pat. 4,887,622. It may also be in the form
of a comb comprising a plurality of application members, obtained
especially by molding. Such combs are described, for example, in
patent FR 2 796 529. The applicator may be solidly attached to the
container, as described, for example, in patent FR 2 761 959.
Advantageously, the applicator is solidly attached to a stem, which
is itself solidly attached to the closing member.
[0258] The closing member may be coupled to the container by
screwing. Alternatively, the coupling between the closing member
and the container takes place other than by screwing, especially
via a bayonet mechanism, by click-fastening or by tightening. The
term "click-fastening" in particular means any system involving the
passing of a rim or bead of material by elastic deformation of a
portion, especially of the closing member, followed by return to
the elastically unstressed position of said portion after the rim
or bead has been passed.
[0259] The container, advantageously comprising two compartments or
reservoirs, may be at least partly made of thermoplastic material.
Examples of thermoplastic materials that may be mentioned include
polypropylene and polyethylene.
[0260] Alternatively, the container is made of a non-thermoplastic
material, especially of glass or metal (or alloy).
[0261] The container is preferably equipped with a drainer located
in the region of at least one aperture of the container. Such a
drainer makes it possible to wipe the applicator and, optionally,
the stem to which it may be solidly attached. Such a drainer is
described, for example, in patent FR 2 792 618.
[0262] The content of the patents or patent applications mentioned
previously are incorporated by reference into the present patent
application.
[0263] According to one particularly preferred embodiment, the
makeup kit comprises two reservoirs each comprising one among the
"base coat" and "top coat" compositions, one of the reservoirs
being equipped with a makeup brush, especially of mascara brush
type as described above, and the other reservoir being equipped
with a means for applying composition (ii) described
hereinbelow.
[0264] Application Means
[0265] The application means included in the kit according to the
present invention comprises a plurality of application members
arranged on a support in the form of at least one row whose length
is such that the application members can at best simultaneously
contact not more than a quarter of the eyelashes of the fringe.
[0266] According to one preferred embodiment, the application means
included in the kit according to the present invention
comprises:
[0267] a stem,
[0268] a support connected to the stem and extending along a
longitudinal axis, and
[0269] a plurality of application members, being only two in
number, where appropriate, arranged on the support and extending
substantially transversely to the longitudinal axis of the
support.
[0270] Thus, according to one most particularly preferred
embodiment, the application means comprises:
[0271] a plurality of application members (6; 60) arranged on a
support (5) in the form of at least one row whose length is such
that the application members (6; 60) can at best simultaneously
contact at most a quarter of the eyelashes of the fringe.
[0272] The application members can extend over a distance along the
longitudinal axis of the support, which is such that the
application members can at best simultaneously contact at most a
quarter, or even a fifth or a sixth of the eyelashes or of the
eyebrows of the fringe, while the longitudinal axis of the support
is oriented substantially tangentially to the fringe.
[0273] A portion of made-up eyelashes or eyebrows may, for example,
correspond to at most a quarter, or even a fifth or a sixth of the
length of the fringe.
[0274] The application members may comprise teeth and/or
bristles.
[0275] This applicator makes it possible to conveniently charge the
eyelashes while at the same time exerting a possible combing
action.
[0276] The application members extend on the support over a
distance that is short enough to be able to make up one or more
locks of eyelashes, which makes it possible to obtain novel makeup
effects.
[0277] This applicator makes it possible to deposit in a supported
manner material on only at most a third, or even a quarter of the
eyelash fringe to be made up, the portion preferably being at the
exterior of the eyelash fringe.
[0278] The application members may extend, for example, on the
support over a distance of between about 0.1 and 1 cm, for example
less than or equal to 8 mm, or even 7 mm or 6 mm, for example a
distance ranging from 2 mm to 5 mm approximately, for example
between 2 mm and 3 mm.
[0279] The applicator included in the kit according to the present
invention may comprise:
[0280] a stem,
[0281] a support connected to the stem and extending along a
longitudinal axis,
[0282] at least one row of application members, consisting
especially of teeth, arranged on the support, the application
members of the row each extending substantially transversely to the
longitudinal axis of the support and having free ends whose
distance to the longitudinal axis varies non-monotonously on moving
between the extreme application members of the row.
[0283] The presence of a maximum in the row of application members
may allow gradual penetration of the application members into the
eyelashes and thus facilitate the makeup of a portion of eyelash
fringe according to the invention.
[0284] The number of application members of the row, especially the
number of teeth, may be, for example, between 3 and 9, preferably
between 3 and 8 and especially between 3 and 7.
[0285] According to one embodiment, the support and the application
members are made as a single piece, especially by molding or
machining. As a variant, the application members may be connected
to the support.
[0286] The support and the stem may be made as a single piece,
especially by molding, or, as a variant, the support may be
connected to the stem. In this case, the support may comprise a tip
arranged so as to engage in housing for the stem, or the stem may
comprise a tip arranged so as to engage in housing for the
support.
[0287] The stem may extend along a longitudinal axis different than
the longitudinal axis of the support. In this case, the
longitudinal axis of the stem may form with the longitudinal axis
of the support, especially for the portion thereof that bears the
application members, an angle of between 5.degree. and 45.degree.,
especially between 15.degree. and 25.degree., for example equal to
20.degree. about. This configuration may allow more comfortable
handling of the applicator during the application of a makeup
composition in accordance with the invention to the eyelashes. The
longitudinal axis of the support may be, for example, curvilinear
or rectilinear.
[0288] As a variant, the stem may extend along a longitudinal axis
that is identical to the longitudinal axis of the support.
[0289] The applicator and/or the support may be at least partially
made of a supple or rigid material, especially at least partially
of thermoplastic, elastomeric or elastomeric-thermoplastic
material, especially by molding. It would not constitute a
departure from the context of the present invention if the
applicator were at least partially made of wood, metal or other
materials, especially by machining.
[0290] When the support is made of an elastically deformable
material, this may make it possible to perform preferential wiping
of one side of the support.
[0291] The stem and the support may or may not be made of different
materials.
[0292] When the applicator is observed from the side, the line
connecting the free ends of the application members may have a
distance to the longitudinal axis of the support that passes
through at least one extremum, especially a maximum, which may make
the penetration of the applicator into the eyelashes more
gradual.
[0293] The abovementioned line may especially have at least
partially a pointed shape, especially triangular, or a rounded
shape, especially circular or ogival.
[0294] Irrespective of the profile of the abovementioned line, when
there is a maximum and a minimum, the angle formed between, on the
one hand, the straight line connecting the free ends of an
application member of the greatest length associated with this
maximum and of an application member of smallest length associated
with the closest minimum of the application member of the longest
length, and, on the other hand, the normal to the longitudinal axis
of the support, this normal passing through the free ends of the
application member of greatest length, is, for example, between
25.degree. and 60.degree. approximately, especially between
25.degree. and 50.degree., especially between 25.degree. and
45.degree., for example between 30.degree. and 45.degree., for
example equal to 43.degree. about.
[0295] The distance from the abovementioned line to the
longitudinal axis of the support may also pass through two or even
more extremes.
[0296] The application members may be arranged in a single row or
in at least two rows. In the latter case, the application members
of a first row and those of a second row may extend in different
directions or, as a variant, in parallel directions. The two rows
may be, for example, arranged substantially opposite each other
relative to the support.
[0297] The height of the application members may be, for example,
between 0.5 and 10 mm approximately and especially between 1 and 3
mm approximately.
[0298] When these application members are arranged in at least one
row, this row may comprise a succession of application members
extending alternately, at least partially, on either side of a
geometrical separating surface.
[0299] The application members may or may not have aligned
bases.
[0300] When the application members are arranged in at least one
row, the row may extend along a non-rectilinear axis. The
application members may also be made alternately on either side of
a median core.
[0301] Again when the application members are arranged in at least
one row, this row may comprise a succession of application members
located alternately, at least partially, on either side of a
geometrical separating surface, two consecutive application members
having adjacent parts that are connected or that overlap when the
applicator is observed from the side, and forming between them a
groove for receiving an eyelash.
[0302] The applicator may comprise a comb or a brush.
[0303] When the applicator comprises a brush, the support may
comprise two twisted wires of small diameter, especially less than
0.7 mm, for example between 0.2 and 0.6 mm and better still between
0.35 and 0.50 mm.
[0304] Still in the case where the applicator comprises a brush,
the application members may be bristles of small diameter, for
example less than or equal to 8/100 mm and better still 6/100
mm.
[0305] When the brush comprises a twisted core, the number of
spires of the brush may be between 3 and 6, for example. In the
case of a brush with a twisted core, the bristles extend from the
core in two helical courses. The number of spires of the brush
corresponds to the sum of the revolutions around the core of the
two courses. Part of the twisted core may be free of bristles,
especially close to the junction between the support and the
stem.
[0306] The cross section of the envelope surface of the brush may
be circular, square or another shape.
[0307] The brush may have a biconical envelope surface. The
envelope surface may also be conical or frustoconical with the base
of the cone located on the side of the distal or proximal end of
the brush.
[0308] The applicator included in the kit according to the
invention may take the form of a brush for the application of a
product to the eyelashes, comprising a twisted core and bristles
extending from the core, the number of spires being less than or
equal to 6.
[0309] The applicator included in the kit according to the
invention may also take the form of a brush for the application of
a product to the eyelashes, comprising a core and bristles
extending from the core, the length of the portion of the brush
bearing the bristles being less than or equal to 8 mm, better still
7 mm or even 6 mm.
[0310] The applicator included in the kit according to the
invention may also take the form of a composition in accordance
with the invention, comprising a core and bristles extending from
the core, contained in an envelope surface of substantially
frustoconical, conical or biconical shape, in which the smallest
angle formed between a plane containing the largest cross section
of the brush and a tangent to the envelope surface of the brush at
the intersection with this plane is between 20.degree. and
60.degree., especially between 25.degree. and 50.degree., for
example between 30.degree. and 35.degree..
[0311] The applicator included in the kit according to the
invention may also take the form of a composition in accordance
with the invention for the eyelashes, comprising a core and
bristles extending from the core, in which the envelope surface of
the brush has a substantially biconical shape, with an apex angle
at the junction of the cone frustums of less than or equal to
120.degree., or even less than or equal to 90.degree..
[0312] The applicator included in the kit according to the
invention may also take the form of a comb for the application of a
product to the eyelashes, comprising a support and teeth extending
transversely to the longitudinal axis of the support, the distance
between the extreme teeth along the longitudinal axis being less
than or equal to 8 mm, better still 7 mm, or even 6 mm.
[0313] The applicator included in the kit according to the
invention may also take the form of a comb for the application of a
product to the eyelashes, comprising a support and teeth extending
transversely to the longitudinal axis of the support, comprising a
tooth of greatest length having a first length and a tooth of
shortest length having a second length, in which comb the ratio of
the first length to the second length is greater than or equal to
1.3.
[0314] The applicator included in the kit according to the
invention may also take the form of a comb for the application of a
product to the eyelashes, comprising a support and teeth extending
transversely to the longitudinal axis of the support, in which the
angle formed between a straight line joining the free end of a
tooth of shortest length and the free end of a tooth of longest
length and the perpendicular to the longitudinal axis of the
support passing through the free end of the tooth of longest length
is between 20.degree. and 60.degree..
[0315] When the kit comprises a wiping member, the applicator
support is profiled so as to facilitate passage into the wiping
member and may comprise for this purpose, for example, a rounded
nose at the front and a bump at the back.
[0316] The applicator stem may be connected to a cap for closing
the container, which may also serve as a handling member, and the
applicator may be housed inside the container when it is in the
closed position.
[0317] The invention may be understood more clearly on reading the
detailed description that follows, of non-limiting examples of
implementation of the application means included in the kit and of
kits per se, and on examining the attached drawing, in which:

according to the makeup process of the invention.
[0339] The device 1, shown in FIG. 1, which corresponds to a part
of the kit when this kit is conditioned in two separate packagings,
comprises a container 2 containing a reserve of a cosmetic product
P, in the present case one of the compositions (i) or (ii), and an
applicator 3 comprising a stem 4 of longitudinal axis X. Only the
device comprising the application means in accordance with the
invention and one of the compositions in accordance with the
invention is shown therein.
[0340] The stem 4 is fitted at one end with a support 5 comprising
a plurality of application members 6 and the stem 4 is connected at
the opposite end to a cap 7 for closing the container 2, which also
constitutes a handling member.
[0341] The closing cap 7 comprises inner threading, not shown, for
screwing onto the externally threaded neck 11 of the container
2.
[0342] The container 2 comprises, in the example described, a
wiping member 8 engaged in the neck 11 and comprising a wiping lip
9 arranged so as to wipe the stem 4 and the support 5 equipped with
the application members 6.
[0343] The wiping member 8 can, where appropriate, be arranged such
that it can become deformed on passage of the application members
6.
[0344] The wiping member 8 may be made by injection molding, for
example of a polyolefin.
[0345] The container 2 is hermetically closed when not in use, by
screwing the closing cap 7 onto the neck 11.
[0346] In the example shown, the applicator 3 comprises a comb, the
application members 6 consisting of teeth. The support 5 extends
along a longitudinal axis Y forming with the longitudinal axis X of
the stem 4 a non-zero angle a, as illustrated especially in FIG. 3.
This angle .alpha. may be between 5.degree. and 45.degree., for
example.
[0347] The application members 6, of which there are six, for
example, are arranged in the example under consideration in a row
10.
[0348] The application members 6 may be positioned on the support 5
in various configurations.
[0349] In the example illustrated, the row 10 comprises a first
series of teeth 6a and a second series of teeth 6b, which are
respectively located on either side of a geometrical separating
surface S, which is in this case a midplane of symmetry of the
comb, parallel to the plane of FIG. 3, and may also constitute a
joint plane for the molding of the comb.
[0350] In the example illustrated, the teeth 6a and 6b are produced
alternately on either side of a common core 15 of the support 5,
which serves basically as a backbone on which the teeth are
connected at the bottom.
[0351] The support 5 is provided at the front with a rounded nose
17, for facilitating its return into the container 2.
[0352] The support 5 comprises, at the rear, a bump 18 for
facilitating the crossing of the wiping member 8 during its removal
from the container 2.
[0353] The application members 6 each comprise a top part 20 ending
with a free end 30 and a bottom part 22 connected to the core 15 of
the support 5.
[0354] In the example under consideration, the application members
6 extend substantially perpendicularly to the axis Y of the support
5.
[0355] The free end 30 of the application members are at a distance
from the longitudinal axis Y that varies non-monotonously on moving
between the end application members of the row 10, i.e. from left
to right in FIG. 3.
[0356] For the purposes of the present invention, the term "varying
non-monotonously" should be understood as meaning that the line
connecting the free ends of the application members has a distance
to the longitudinal axis of the support that passes through at
least one extremum, for example a maximum.
[0357] In the example illustrated, the line L connecting the free
ends 30 has, when the applicator is observed from the side, in a
direction perpendicular to the longitudinal axis of the stem 4 and
to the abovementioned geometrical separating surface, as
illustrated in FIG. 3, a substantially triangular shape, with two
rectilinear segments forming between them an angle substantially
equal to 90.degree. in the drawing.
[0358] In the example under consideration, the succession of
application members 6 comprises two larger teeth 6a and 6b of the
same length.
[0359] The straight line D.sub.1 passing through the free end of
the shortest member starting from the distal end of the applicator
and through the free end of the longest member that is closest to
this longest member is identical in the example under consideration
to the first rectilinear segment of the line L.
[0360] The angle .gamma..sub.1 formed between the straight line
D.sub.1 and the perpendicular N.sub.1 to the axis Y passing through
the free end of the abovementioned longest application member is,
for example, between 25.degree. and 60.degree., for example about
43.degree..
[0361] The straight line D.sub.2 passing through the shortest
application member from the proximal end of the support 5 and the
longest application member that is closest to this member is
identical to the second rectilinear segment of the line L.
[0362] The angle .gamma..sub.2 formed between the straight line
D.sub.2 and the perpendicular N.sub.2 to the axis Y passing through
the free end of this longest application member may be within the
same ranges of values as the angle .gamma..sub.1, for example
substantially equal to .gamma..sub.1. The apex angle between the
segments of the line L is, for example, less than or equal to
120.degree., or even less than or equal to 90.degree..
[0363] The application members 6 extend on the support 5 over a
relatively short distance d, especially a distance d of between 0.1
and 1 cm approximately. Thus, as illustrated in FIG. 2, it is
possible, using the applicator 3, to make up only a portion of the
eyelash fringe at a time without touching all of the eyelashes of
the eyelid. For example, the application members can simultaneously
contact, at most, less than a quarter of the eyelashes of the upper
eyelid, as illustrated.
[0364] The support 5 and the application members 6 are made as a
single piece in the example illustrated, by molding plastic. The
support 5 is connected to the stem 4 in a manner that will be
detailed later, with regard to FIGS. 10 and 11.
[0365] In the example described, the top parts 20 of two
consecutive application members 6 form between them a groove 21
extending substantially down to the core 15, when the comb is
observed from the side, as in FIG. 3. The grooves 21 allow the
eyelashes to be captured more easily, for example so as to separate
them, comb them or spread out product deposited on their
surface.
[0366] It is understood that by varying the length and interval of
the application members, it is easily possible to modify the amount
of product that the applicator takes up.
[0367] The gap between the peaks of two successive application
members 6a or 6b located on the same side of the geometrical
separating surface is, in the example under consideration, markedly
larger than the width of an application member, measured at
approximately mid-height of the applicator 3, parallel to the axis
Y of the support 5.
[0368] Each application member 6a extends substantially at
mid-distance, when the applicator 3 is observed from the side, from
two adjacent application members 6b, and vice versa.
[0369] In the example under consideration, the top parts 20 of the
application members 6 all point in substantially the same
direction.
[0370] The bottom parts 22 of two successive application members
located on the same side of the core 15 form between them and with
the core 15 a cavity 23 that can constitute a product reserve.
[0371] The spacing between the application members 6a or 6b may be
relatively large to improve the amount of product that the
applicator takes up, without, however, the applicator losing any
capacity to grip the eyelashes, by virtue of the staggering of the
application members and by the fact that the grooves 21 formed by
the top parts 20 of the application members remain sufficiently
straight.
[0372] The application members 6 may have many configurations
without departing from the context of the present invention,
especially differently oriented top parts.
[0373] It would not constitute a departure from the context of the
present invention if the application members 6 were to be arranged
differently on the support 5.
[0374] FIGS. 5 and 6 show another example of an applicator
comprising a plurality of teeth 6, for example seven teeth,
extending in a row 10. The teeth 6, as may be seen in FIG. 6, have
aligned bases 22, whereas the top parts 20 of two consecutive teeth
6a and 6b diverge.
[0375] FIG. 7 illustrates the possibility of producing the stem 4
with a longitudinal axis X that is identical to that Y of the
support 5.
[0376] In FIG. 8, the support 5 is shown with a longitudinal axis Y
forming a non-zero angle .alpha. with the longitudinal axis X of
the stem 4, the sense of the incline of the support in FIG. 8 being
opposite that of the support in FIGS. 1 to 4.
[0377] The support 5 may be made as a single piece with the stem 4,
for example by molding plastic as illustrated in FIG. 9. However,
the support 5 may also be connected to the stem 4.
[0378] In the example shown in FIG. 10, the support 5 comprises a
substantially cylindrical tip 35 comprising an annular channel 36.
The stem 4 comprises a corresponding housing 37, fitted with an
annular rim 38 arranged so as to click into the channel 36.
[0379] The tip 35 may also be configured so as to be force-fitted
into the stem 4.
[0380] In the example in FIG. 11, the stem 4 comprises a
substantially cylindrical tip 40, arranged so as to house in a
corresponding housing 41 of the support 5.
[0381] The applicator 3 may comprise a number of teeth of less than
six or seven, and may especially comprise only two teeth 6 as
illustrated in FIG. 12. The teeth may or may not have the same
width.
[0382] The line L connecting the free ends 30 of the application
members 6 may have various shapes other than that of FIGS. 1 to 11,
as illustrated in FIGS. 13 to 17.
[0383] In particular, the line L may have a rounded shape,
especially a substantially circular shape as illustrated in FIG.
13, or an ogival shape as illustrated in FIG. 14. The extremum may
be located substantially in the middle of the support 5 as
illustrated previously, may be closer to the stem 4 as illustrated
in FIG. 15 or may be closer to the distal end of the applicator as
illustrated in FIG. 16. The distance from the line L to the
longitudinal axis Y of the support 5 may pass through two extreme
as illustrated in FIG. 17.
[0384] It may be seen in FIG. 13 that the support may be without
the rounded nose 17 and/or the bump 18.
[0385] This figure also shows the straight lines D.sub.1 and
D.sub.2 and the normal N to the longitudinal axis Y of the support
5 that passes through the free end of the longest application
member, which is unique in the example under consideration.
[0386] The angles .gamma..sub.1 formed between the straight line
D.sub.1 and this normal N and .gamma..sub.2 formed between the
straight line D.sub.2 and this normal N may be identical or
different, for example being within the ranges of values given
previously.
[0387] In the example in FIG. 17, angles .gamma..sub.1 and
.gamma..sub.2 relative to the normal N passing through the free end
of the application member associated with the first relative
extremum and .gamma.'.sub.1 and .gamma.'.sub.2 relative to the
normal N' passing through the free end of the application member
corresponding to the second relative extremum may be defined, these
angles also being, for example, within the ranges of values given
previously.
[0388] FIG. 18 illustrates the possibility of producing on the
support 5 two rows of application members, for example two rows
located opposite each other relative to the core 15 of the support
5. The application members may extend differently from one row to
the other and especially, as illustrated in FIG. 18, may have
different profiles when the applicator 3 is observed from the
side.
[0389] The core 15 may have in cross section a circular shape as
illustrated in FIGS. 19, 20 and 22, or another shape, for example
flattened, especially substantially rectangular, as illustrated in
FIG. 21.
[0390] The support 5 may comprise a row of aligned teeth, as
illustrated in FIG. 19, or several rows of teeth extending in
different directions, for example divergent as illustrated in FIG.
20 or in parallel directions as illustrated in FIG. 21.
[0391] An applicator comprising a plurality of rows 10, arranged
around the entire periphery of the core 15 of the support 5, is
illustrated in FIG. 22.
[0392] The application members 6 may have, when the applicator is
observed from the side, over at least part of their length, a
profile of substantially constant width, as illustrated in FIGS. 1
to 22. The application members 6 may also have a different profile,
especially substantially triangular, as illustrated in FIG. 23, or
yet another profile.
[0393] The application members may be arranged in zigzag, as
illustrated in FIG. 24.
[0394] The wiping member 8 may be different than that illustrated
in FIG. 1, without departing from the scope of the present
invention. A device whose wiping member 8 consists of an alveolar
material, especially an open-cell or closed-cell foam, is shown by
way of example in FIG. 25.
[0395] As a variant, the wiping member 8 may be made of elastomer
and may comprise at least one slit 50 as illustrated in FIG. 26.
The wiping member 8 may comprise an annular lip 51 as illustrated
in FIG. 27, other than at its lower end.
[0396] The application members may be other than teeth, and may
comprise bristles, for example, connected to the support as
illustrated in FIG. 28. The applicator 3 then comprises, for
example, a brush whose bristles 60 extend substantially
transversely to the longitudinal axis Y of the support, which may
be identical to the longitudinal axis X of the stem 4 as
illustrated.
[0397] In the example under consideration, the bristles extend over
a distance d along the longitudinal axis Y of the support, which is
such that the bristles cannot simultaneously contact more than a
quarter of the eyelashes or eyebrows of the eyelash or eyebrow
fringe that it is desired to make tip. The distance d may be, for
example, between 2 and 3 mm approximately, and the number of spires
may be between 3 and 6, for example.
[0398] When the applicator 3 is observed from the side, as
illustrated in FIG. 28, the line L connecting the free ends of the
bristles may have a distance to the axis Y that passes through at
least one extremum.
[0399] When the applicator 3 comprises a brush, the bristles 60
used are preferably relatively fine, for example about 6/100 mm in
diameter.
[0400] The bristles 60 may have a solid, substantially circular
cross section.
[0401] The core 61 may be formed by a metal wire folded into a U
and whose arms are twisted about themselves so as to grip the
bristles between them.
[0402] The metal wire used is preferably relatively fine, for
example with a diameter of less than 0.7 mm and especially between
0.35 and 0.5 mm.
[0403] FIGS. 29 to 35 show applicator variants.
[0404] In FIG. 29, the applicator 3 comprises a brush with a
substantially conical or frustoconical envelope surface, the
longest bristles being on the side of the stem 4.
[0405] The angle .delta. formed between the perpendicular to the
longitudinal axis Y of the brush passing through the largest cross
section and the tangent to the envelope surface is, for example,
between 20.degree. and 60.degree..
[0406] The applicator 3 of FIG. 30 comprises a brush of
substantially biconical envelope surface, whereas that in FIG. 31
comprises a brush of substantially conical or frustoconical
envelope surface, the shortest bristles being on the side of the
stem 4.
[0407] The longitudinal axis Y of the brush may or may not be
aligned with the axis X of the stem.
[0408] The axis Y may form an angle a with the axis X of the stem,
as illustrated in FIGS. 32 to 35. The angle .alpha. may be, for
example, between 5.degree. and 45.degree. approximately, for
example equal to 20.degree. approximately.
[0409] The envelope surface E of the brush may be of circular cross
section as illustrated in FIG. 36, or of other cross section,
especially polygonal or oblong or with notches or gaps.
[0410] When the twisted core is bent, the bend may be more or less
close to the stem 4, as illustrated in FIGS. 32 to 35.
[0411] In variants that are not illustrated, the core is
curved.
[0412] FIG. 37 shows another implementation variant of the
invention.
[0413] FIG. 37 shows a part of the kit according to the invention
in which one of the compositions in accordance with the invention
is contained in a container 2 in the form of a flexible tube.
[0414] Other distribution modes may be used to deposit to said
composition onto the applicator 3, for example a pump distributor,
without departing from the scope of the present invention.
[0415] FIG. 38 shows a kit in accordance with the invention, in the
form of one and the same packaging, comprising a container 2
containing a composition in accordance with the invention and the
applicator 3, and also a second container 70 containing the second
composition in accordance with the invention and a second
applicator 71 that may be different than the applicator 3. For
example, the applicator 71 may comprise a conventional mascara
brush.
[0416] In the example illustrated in FIG. 38, the container 2
comprises a lower skirt 72 fitted with threading and constituting a
closing cap for the container 70.
[0417] The applicator 71 can make it possible, for example, to
apply to the eyelashes the first composition, and the user can then
use the applicator 3 to make up only a portion of the eyelash
fringe, advantageously at most a third of said fringe, and even
more preferably, the outer portion of the eyelash fringe, over at
most a third of the fringe.
[0418] Other examples of devices comprising two containers and two
applicators have been shown in FIGS. 39 to 42.
[0419] The applicators in these examples are oriented in opposite
directions such that each container can serve as a gripping member
for the applicator associated with the other container.
[0420] In FIG. 39, the device comprises a mascara brush and an
applicator 3 in accordance with the invention comprising a comb,
whereas the applicator 3 of the device in FIG. 40 comprises a
brush. The mascara brush may be chosen, for example, from those
described in U.S. Pat. No. 5,937,870 or FR 2 605 505, for example,
the content of which is incorporated into the present patent
application by reference.
[0421] The device in FIG. 41 comprises a comb and an applicator 3
in accordance with the invention, also consisting of a comb. The
applicator in FIG. 42 comprises a comb and an applicator in
accordance with the invention, consisting of a brush. The comb of
the applicators 71 in FIGS. 41 and 42 is chosen, for example, from
those described in U.S. Pat. No. 6,581,610, WO 01/05271 or U.S.
Pat. No. 6,539,950, the content of which is incorporated into the
present patent application by reference.
[0422] The devices in FIGS. 39 to 42 comprise a tubular sleeve 80
connecting together the closing caps 82 and 7 associated,
respectively, with the containers 70 and 2. The closing caps 82 and
7 may be retained, for example, by friction, bonding or
click-fastening inside the sleeve 80.
[0423] FIG. 43 shows an eye made up according to the process of the
invention, using a kit according to the invention. It is observed
that the outer portion of the eyelash fringe comprises more
deposited material. There is no regrettable formation of lumps, and
a particular makeup effect is obtained.
[0424] Needless to say, the invention is not limited to the
implementation examples that have just been described. The
characteristics of the various embodiments may especially be
combined.
[0425] In the implementation examples of the invention, the
application members may extend transversely to the stem or to the
wiping member.
[0426] Process
[0427] A subject of the invention is a nontherapeutic process for
making up and/or caring for the eyelashes, characterized in that it
comprises:
[0428] at least one step of applying to the eyelashes at least one
coat of a composition (i) with a content of wax(es) and of
hydrophilic polymer(s) of less than or equal to 26% by weight
relative to the total weight of the composition, and
[0429] at least one step of applying at least one coat of a
composition (ii) with a total content of wax(es) and of hydrophilic
film-forming polymer(s) of greater than 26% by weight relative to
the total weight of the composition,
at least one of said compositions (i) and (ii) comprising a
continuous aqueous phase, the step of applying composition (ii)
being performed using the application means described above.
[0430] According to a preferred embodiment, composition (i) is
applied before composition (ii). Advantageously, composition (ii)
is furthermore applied to only a portion of the eyelash fringe. In
this way, the production of contrast in terms of differential
charging is optimum.
[0431] Thus, the makeup process may comprise the steps consisting
in:
[0432] applying the first composition (i) in accordance with the
invention to substantially all of the eyelash fringe, so as to form
a first deposit, and
[0433] on the first deposit of the portion formed by at most the
outer third of the eyelash fringe, forming a second deposit by
means of a one second composition (ii) in accordance with the
invention.
[0434] It is possible, for example, to form the second deposit
before the first composition has fully dried.
[0435] The second portion may extend over at least a sixth of the
total length of the eyelash fringe.
[0436] The made-up fringe may be that of the eyelashes of the upper
eyelid.
[0437] According to another particular embodiment, composition (i)
is applied to the entire eyelash fringe and composition (ii) is
applied only to at most a third of the eyelash fringe, preferably
to at most the outer third of the eyelash fringe, or even to at
most a quarter of said fringe. The portion of eyelash fringe on
which composition (i) may be deposited may represent from an eighth
to a third and preferably from a quarter to a third of the total
length of the eyelash fringe.
[0438] The present invention is illustrated by the examples that
follow. Unless otherwise mentioned, the amounts indicated are
expressed as mass percentages relative to the total weight of the
composition.
[0439] The hydrophilic polymers are indicated as such in the
examples that follow.

[0442] All the combinations of compositions (i) and (ii) as
described above may be envisioned.
[0443] According to one particular embodiment, the composition
described in Example 2 is applied as composition (i), and the
composition described in Example 7 is applied as composition (ii).
A particular makeup effect in accordance with that shown in FIG.
43, i.e. which opens the gaze and enlarges the eyes, optically
modifying the perception of the shape of the eyes, is thus
obtained, in particular when composition (ii) is applied to at most
the outer third of the eyelash fringe.
[0444] Although the present invention herein has been described
with reference to particular embodiments, it is to be understood
that these embodiments are merely illustrative of the principles
and applications of the present invention. It is therefore to be
understood that numerous modifications may be made to the
illustrative embodiments and that other arrangements may be devised
without departing from the spirit and scope of the present
invention as defined by the appended claims.
