Description
[0001] This application claims benefit of U.S. Provisional
Application No. 60/620,429, filed Oct. 21, 2004, the contents of
which are incorporated herein by reference. This application also
claims benefit of priority under 35 U.S.C. .sctn. 119 to French
Patent Application No. 04 51397, filed Jul. 1, 2004, the contents
of which are also incorporated by reference.
[0002] In one embodiment, the present disclosure relates to a
pressurized hair composition comprising at least one elastomeric
film-forming polymer and at least one propellant, and the use of
the composition for styling the hair.
[0003] Styling compositions, such as lacquers and sprays, packaged
in the form of an aerosol spray, are generally composed of a liquid
phase comprising, in a cosmetically acceptable alcoholic or
aqueous-alcoholic medium, at least one film-forming polymer, and a
propellant that is a liquefied gas under reduced pressure or
dissolved in the liquid phase.
[0004] In the hair products field, it may be desirable to produce
aerosol lacquers that contain no volatile organic compound such as
ethanol or dimethyl ether, for essentially ecological reasons,
while at the same time conserving good properties with respect to
shaping and holding the hair style.
[0005] The difficulty is to obtain good spraying conditions and a
lacquer that has shaping and holding properties entirely equivalent
to those of the commonly used lacquers and contains no volatile
organic compound.
[0006] The present inventors have found that the use, in
pressurized hair compositions, of certain elastomeric film-forming
polymers results in formulations that may be readily sprayable,
such as when they contain a high proportion of water. These
compositions may be readily applied to the hair and, surprisingly,
may give the appearance of dry hair much more rapidly than the
known polymers that were tested. The elastomeric film-forming
polymers may exhibit a satisfactory styling capacity and may be
easily removed by simple shampooing. Brushing the treated hair may
not result in a powdering effect, but may leave the hair soft and
shiny.
[0007] Disclosed herein is a hair composition, packaged in an
aerosol device, comprising, in a cosmetically acceptable medium, at
least one elastomeric film-forming polymer chosen from non-ionic,
anionic, amphoteric and cationic elastomeric film-forming polymers
comprising at least one fluoro group, wherein the at least one
elastomeric film-forming polymer is chosen such that the material
obtained by drying this polymer, at ambient temperature and at a
relative humidity of 55%.+-.5%, has a mechanical profile defined by
at least: [0008] a) an elongation at break (.epsilon.) of greater
than or equal to 800%; [0009] b) an instantaneous recovery
(R.sub.i) of greater than or equal to 75%, after an elongation of
150%; and [0010] c) a recovery (R.sub.300s) at 300 seconds of
greater than 80%, and at least one propellant.
[0011] Further disclosed herein is the use of such a hair
composition for styling the hair.
[0012] As used herein, the term "film obtained by drying at ambient
temperature (22.degree. C..+-.2.degree. C.) and at a relative
humidity of 55%.+-.5%" means the film obtained, under these
conditions, from a mixture containing 6% of active material (AM) of
the elastomeric film-forming polymer in a mixture of 30% by weight
of ethanol and 70% by weight of water, relative to the total weight
of alcohol+water, the amount of mixture being adjusted so as to
obtain, in a Teflon matrix, a film 500 .mu.m.+-.50 .mu.m thick. The
drying is continued until the weight of the film no longer changes,
which lasts approximately 12 days. The film-forming polymers that
are soluble or partially soluble in ethanol are tested in ethanol
alone. The other polymers are tested in water alone, in soluble or
dispersed form. The relative humidity can readily be determined by
one of ordinary skill in the art using the known techniques.
[0013] As used herein, the elongation at break and the recovery
rate are evaluated by the tests described below.
[0014] To carry out the tensile tests, the film is cut into
rectangle-shaped test pieces, 80 mm long and 15 mm wide.
[0015] The tests are carried out on a device sold under the name
Lloyd or sold under the name Zwick, under the same temperature and
humidity conditions as for the drying, i.e., a temperature of
22.degree. C..+-.2.degree. C. and a relative humidity of
55%.+-.5%.
[0016] The test pieces are drawn at a rate of 20 mm/min and the
distance between the jaws is 50.+-.1 mm.
[0017] To determine the instantaneous recovery (R.sub.i), the
following procedure is carried out: [0018] the test piece is drawn
by 150% (.epsilon..sub.max), i.e., 1.5 times its initial length
(l.sub.0), [0019] the stress is released by applying a return speed
equal to the tensile speed, i.e., 20 mm/min, and the elongation of
the test piece is measured as a percentage, after returning to zero
constraint (.epsilon..sub.i).
[0020] The % instantaneous recovery (R.sub.i) is given by the
formula below:
R.sub.i=((.epsilon..sub.max-.epsilon..sub.i)/.epsilon..sub.max).t-
imes.100
[0021] To determine the recovery at 300 seconds, the test piece,
having undergone the above operations, is maintained at zero
constraint for a further 300 seconds, and its percentage elongation
(.epsilon..sub.300s) is measured.
[0022] The % recovery at 300 seconds (R.sub.300s) is given by the
formula below:
R.sub.300s=((.epsilon..sub.max-.epsilon..sub.300s)/.epsilon..sub.-
max).times.100
[0023] For example, the at least one elastomeric film-forming
polymer of the composition disclosed herein, optionally combined
with at least one agent chosen from plasticizers and film-forming
agents, is such that it forms under the conditions of the above
tests, a film having an elongation at break ranging from 800% to
3000%; an instantaneous recovery ranging from 75% to 100%; and a
recovery at 300 seconds ranging from 85% to 100%.
[0024] In one embodiment, the at least one elastomeric film-forming
polymer of the composition disclosed herein is such that it forms
at ambient temperature and at a relative humidity ranging from 30%
to 80%, a film having an elongation at break ranging from 400% to
1200% and/or an instantaneous recovery ranging from 57% to 93%.
[0025] For example, in some of the compositions disclosed herein,
the at least one elastomeric film-forming polymer is present in an
amount ranging, for example, from 0.05% to 20% by weight, such as
from 0.1% to 15% by weight, and further such as from 0.25% to 10%
by weight, relative to the total weight of the composition.
[0026] In one embodiment, the at least one elastomeric film-forming
polymer is chosen from polyurethanes, polyvinyl alcohols, and
polymers comprising at least one (meth)acrylic unit. It may be in
the form of a homopolymer or a copolymer. For example, it is in a
non-crosslinked form in the composition.
[0027] The composition may also comprise at least one auxiliary
film-forming agent chosen from plasticizers and agents for
facilitating the formation of a film of the at least one
elastomeric polymer on keratin materials, the function of which is
to modify the properties of the at least one elastomeric polymer.
Such an auxiliary film-forming agent can be chosen from any of the
compounds known to those skilled in the art to be capable of
performing the desired function, and can, for example, be chosen
from plasticizers and coalescence agents. The at least one
elastomeric film-forming polymer, optionally combined with at least
one auxiliary film-forming agent chosen from plasticizers and
agents for facilitating film formation, are capable of forming a
film, after evaporation of the cosmetic medium. This evaporation
can be carried out in the open air or by supplying heat, for
example, by a dryer.
[0028] As an example of the plasticizers and the agents for
facilitating film formation on keratin materials, use may be made
of those described in document FR-A-2 782 917. For example, the at
least one auxiliary film-forming agent is chosen from the common
plasticizers and coalescence agents, such as: [0029] glycols and
their derivatives, such as diethylene glycol ethyl ether,
diethylene glycol methyl ether, diethylene glycol butyl ether or
alternatively diethylene glycol hexyl ether, ethylene glycol ethyl
ether, ethylene glycol butyl ether, ethylene glycol hexyl ether or
pentylene glycol, [0030] glyceryl esters, [0031] derivatives of
propylene glycol, such as propylene glycol phenyl ether, propylene
glycol diacetate, dipropylene glycol butyl ether, tripropylene
glycol butyl ether, propylene glycol methyl ether, dipropylene
glycol ethyl ether, tripropylene glycol methyl ether, diethylene
glycol methyl ether and propylene glycol butyl ether, [0032] acid
esters, for example, carboxylic acid esters such as citrates,
phthalates, adipates, carbonates, tartrates, phosphates or
sebacates, and [0033] mixtures thereof.
[0034] The amount of the at least one auxiliary film-forming agent
can be chosen by those skilled in the art based on their general
knowledge, so as to obtain a polymeric system (elastomeric
polymers+the at least one auxiliary film-forming agent) that
produces a film having the desired mechanical properties, while at
the same time allowing the composition to keep the desired cosmetic
properties. In practice, this amount ranges, for example, from
0.01% to 25% by weight, such as from 0.01% to 15% by weight,
relative to the total weight of the composition.
[0035] In one embodiment, in the compositions disclosed herein, the
at least one elastomeric film-forming polymer is soluble in an
aqueous-alcoholic medium.
[0036] As used herein, the term "compounds soluble" in a given
medium means compounds (such as monomers or polymers) which, when
introduced into the medium at 25.degree. C., at a concentration by
weight equal to 10%, if need be neutralized, make it possible to
obtain a solution that is macroscopically homogeneous and
transparent, i.e., that has a light transmission value, at a
wavelength equal to 500 nm, through a sample 1 cm thick, of least
70%, such as at least 80%.
[0037] The term "compounds dispersible" in a medium means compounds
(such as monomers or polymers) which, when introduced into the
medium at 25.degree. C., at a concentration by weight of greater
than or equal to 1%, make it possible to obtain a non-transparent
homogeneous dispersion.
[0038] For example, the material obtained by drying the polymer
disclosed herein, at ambient temperature and at a relative humidity
of 55%.+-.5%, is water-soluble and/or water-dispersible.
[0039] In one embodiment, an aqueous-alcoholic solution of 5% by
weight of the at least one elastomeric film-forming polymer
disclosed herein, comprising 30% by weight of water made up to 100%
by weight with alcohol, has a viscosity of greater than 20 cps and
less than 200 cps at 25.degree. C.
[0040] The viscosity is measured with a Rheomat 180 viscometer.
[0041] The elastomeric film-forming polymers that are useful in the
composition disclosed herein are chosen from those known in the
art. They may, for example, be synthesized according to the method
described in French patent application FR 2 815 350.
Aerosol Device
[0042] The term "cosmetically acceptable medium" as used herein
means a medium consisting of water or one or more cosmetically
acceptable organic solvents, for instance C.sub.1-C.sub.4 lower
alcohols, such as ethanol, isopropanol, tert-butanol and n-butanol,
and alkylene glycols such as propylene glycol, or alternatively a
mixture of water and at least one cosmetically acceptable organic
solvent.
[0043] The composition of the cosmetically acceptable medium and
its proportion in the final hair composition are such that the
overall content, in the hair composition, of volatile organic
compounds (VOCs) is, for example, at most 55% by weight.
[0044] The at least one propellant may be any liquefiable gas
normally used in aerosol devices, such as dimethyl ether, C.sub.3-5
alkanes, 1,1-difluoroethane, mixtures of dimethyl ether and
C.sub.3-5 alkanes, and mixtures of 1,1-difluoroethane and at least
one compound chosen from dimethyl ether and C.sub.3-5 alkanes.
[0045] Dimethyl ether and C.sub.3-C.sub.5 alkanes, such as propane,
n-butane and isobutane, are, for example, used as the
propellant.
[0046] The liquid phase/propellant weight ratio in the pressurized
hair compositions disclosed herein ranges, for example, from 0.05:1
to 50:1, such as from 1.5:1 to 25:1.
[0047] The hair compositions disclosed herein can also comprise at
least one ingredient chosen from cosmetic and formulation
ingredients, normally used in the cosmetics field.
[0048] By way of examples of such ingredients, mention may be made
of anionic, cationic, non-ionic or amphoteric film-forming polymers
other than the at least one elastomeric film-forming polymer
described above, volatile or non-volatile silicones, anionic,
cationic, amphoteric or non-ionic surfactants, thickeners,
pearlescent agents, UV-screening agents, free-radical scavengers,
fragrances, preserving agents, pigments and dyes, pH modifiers,
solubilizing agents, plasticizers, anti-foaming agents, waxes and
oils, vitamins, conditioning agents, and organic or mineral
particles that are synthetic or of natural origin.
[0049] If the aerosol device that is used to package the
compositions disclosed herein is a two-compartment device, it may
comprise an outer aerosol can comprising an inner pocket
hermetically welded to a valve. The composition is introduced into
the inner pocket and a compressed gas is introduced between the
pocket and the can at a pressure that is sufficient to eject the
product in the form of a spray through the orifice of a nozzle.
Such a device is sold under the name EP Spray by the company
EP-Spray System SA. The compressed gas is, for example, used at a
pressure ranging from 1 to 12 bar, such as from 9 to 11 bar.
[0050] Of course, those skilled in the art will take care to choose
this or these optional additional additive(s) and/or the amount(s)
thereof in such a way that the intrinsic advantageous properties of
the compositions disclosed herein are not impaired by the
addition(s) envisaged.
[0051] The hair compositions are, for example, hair lacquers or
mousses.
[0052] Other than in the operating examples, or where otherwise
indicated, all numbers expressing quantities of ingredients,
reaction conditions, and so forth used in the specification and
claims are to be understood as being modified in all instances by
the term "about." Accordingly, unless indicated to the contrary,
the numerical parameters set forth in this specification and
attached claims are approximations that may vary depending upon the
desired properties sought to be obtained by the present disclosure.
At the very least, and not as an attempt to limit the application
of the doctrine of equivalents to the scope of the claims, each
numerical parameter should be construed in light of the number of
significant digits and ordinary rounding approaches.
[0053] Notwithstanding that the numerical ranges and parameters
setting forth the broad scope of the disclosure are approximations,
the numerical values set forth in the specific examples are
reported as precisely as possible. Any numerical value, however,
inherently contains certain errors necessarily resulting from the
standard deviation found in their respective testing
measurements.
[0054] The present disclosure is illustrated by the following
non-limiting examples.
