Description
TECHNICAL FIELD
[0001] The present invention relates to a composition for dyeing
keratin fibers, in particular human keratin fibers such as
hair.
BACKGROUND
[0002] Many people have for a long time sought to modify the colour
of their hair, and especially to dye it in order, for example, to
mask their grey hair.
[0003] "Permanent" dyeing methods also known as oxidative dyeing,
which use colorant compositions containing oxidative dye
precursors, generally referred to as oxidation bases, such as
ortho- or para-phenylenediamines, ortho- or para-aminophenols and
heterocyclic compounds, have been developed for dyeing human
keratin fibers in a long-lasting manner. These oxidation bases are
colourless or weakly coloured compounds, which, when combined with
oxidizing products, may give rise to coloured compounds via a
process of oxidative condensation.
[0004] The dyeing product can comprise both at least one oxidative
dye and at least one oxidant. For better use, the oxidative dye and
the oxidant may be placed respectively in a multi-compartment
package, and are mixed together immediately before use.
[0005] Consumers desire using dyes for dyeing only the target area.
However, in many cases, e.g., when dyeing hair, some other areas
may be undesiredly dyed (stained), such as hand, face, ear and the
like. Consumers have to pay more attention to avoid the undesired
areas, and have been seeking for products help them to remedy the
undesired dyeing.
SUMMARY OF THE INVENTION
[0006] The inventors have now discovered that the use of a specific
retardant together with an oxidative dye makes it possible to
obtain a composition for the oxidative dyeing of keratin fibers,
which can overcome the above drawbacks, especially reducing or even
substantially avoiding of stain by dye to a non-target
position.
[0007] One subject of the present invention is thus a dye package
for the oxidative dyeing of keratin fibers comprising:
[0008] (A) a dyeing composition (A); and
[0009] (B) an AMPS composition (B) comprising an AMPS polymer.
[0010] Preferably, the AMPS composition (B) is placed in a chamber
separate from the dyeing composition (A).
[0011] According to an embodiment of the invention, the dyeing
composition (A) may in turn comprise:
[0012] (I) a colorant composition (I), comprising: [0013] i) at
least one oxidative dye(s); and
[0014] (II) a developer composition (II), comprising: [0015] ii) at
least one developer.
[0016] The present invention thus provides use of an AMPS polymer,
used as a retardant, for slowing down reactions of dye or
intermediates thereof.
[0017] The present invention also provides use of an AMPS polymer
for reducing stain of a dye.
[0018] The present invention also relates to a process for dyeing
keratin fibers, in particular human keratin fibers such as the
hair, using the dyeing composition (A) according to the
invention.
[0019] The present invention also relates to a process of slowing
down reactions of dye or intermediates thereof, characterized in
mixing an AMPS polymer with the dye. Preferably, the AMPS polymer
is mixed with the dye before application of the dye, or the AMPS
polymer is applied to the position to which the dye has been
applied for less than 10 minutes, less than 5 minutes, or less than
3 minutes.

[0075] Other Antioxidant
[0076] In addition to the reducer introduced above, one or more
other antioxidant can also be used for the colorant composition (I)
according to the present invention.
[0077] The antioxidants used may include natural exogenous
phytochemical antioxidants such as phenols and carotenoids.
[0078] The antioxidant can include flavonoids. Flavonoids
constitute a large class of more than 5,000 polyphenolic
phytochemicals with antioxidant properties that act by direct free
radical scavenging. Flavonoids have anti-inflammatory,
antibacterial, antiviral, anti-allergic, anti-mutagenic,
anti-thrombotic, anti-tumor and vasodilating effects and these
methods of action can also be used to prevent, alleviate or
eliminate oxidative damage from dental instruments. Flavonoids also
exhibit chelation properties with metal ions and can mitigate
oxidative damage from metal ions by chelating ions. The formation
and stability of flavonoid-metal chelate is dependent on the
function of the structure. Flavonoids having a catechol moiety and
having a hydrogen bond between the hydroxyl groups at the
5-position and the 3-position have chelation properties.
[0079] Vitamin C and derivatives can be used, including ascorbic
acid, erythorbic acid, or derivatives thereof, e.g., sodium
ascorbate/erythorbate and the fat-soluble ester tetrahexyl decyl
ascorbate/erythorbate and ascorbyl palmitate, magnesium ascorbyl
phosphate, ascorbyl glucoside, glucosamine ascorbate, ascorbyl
acetate, and the like. In addition, it is also possible to use
plants derived from a large amount of vitamin C, such as extracts
of Myrciaria dubia, acerola, Emblica officinalis, and bioflavonoids
from rose hips and citrus, including Water-soluble bioflavonoids
such as hesperidin methyl chalcone.
[0080] Sesamum indicum or lignan may also be added. Sesame and its
lignans (fibrous compounds associated with sesame) act as
antioxidants. Sesame seed lignan significantly enhances vitamin E
activity.
[0081] Other antioxidants which may be incorporated into the
compositions of the present invention include tocopherols (e.g.,
d-alpha-tocopherol, d-beta-tocopherol, d-gamma-tocopherol,
d-delta-tocopherol), tocotrienol Phenol (eg d-.alpha.-tocotrienol,
d-.beta.-tocotrienol, d-.gamma.-tocotrienol, d-.delta.-tocotrienol)
and vitamin E (.alpha.-tocopheryl acetate)). These compounds can be
isolated from natural sources, prepared by synthetic means or
mixed. The tocotrienol-rich vitamin E preparation can be obtained
by fractionating the vitamin E preparation to remove a portion of
the biophenol and recovering the higher concentrated tocotrienol
product. Useful tocotrienols are natural products isolated, for
example, from wheat germ oil, grain or palm oil using high
performance liquid chromatography or from barley, distiller's
grains or oats by alcohol extraction and/or molecular distillation.
The term "tocotrienol" as used herein includes a tocotrienol-rich
fraction obtained from these natural products as well as a pure
compound. Increased glutathione peroxidase activity protects the
skin from oxidative damage.
[0082] In addition, carotenoids, especially lutein types, are also
useful antioxidants that can be used. Lutein-type carotenoids
include molecules such as lutein, canthaxantin, cryptoxanthin,
zeaxanthin and astaxanthin. Lutein compounds protect compounds such
as vitamin A, vitamin E and other carotenoids.

collagenase inhibitors. Inhibition of collagenase helps prevent and
reduce wrinkles caused by skin collagen reduction, increase skin
elasticity, and the like. Anthocyanins can be obtained from any
part of a variety of plant sources, such as solids, flowers, stems,
leaves, roots, bark or seeds. Those skilled in the art will
appreciate that certain portions of the plant may contain higher
natural levels of anthocyanins, and thus these moieties are used to
obtain the desired anthocyanins. In some cases, the antioxidant can

[0285] As stated above, the inventor has surprisingly discovered
that the AMPS polymer can be used as a retardant to slow down
reactions of dye or intermediates thereof, e.g., the oxidative dye
i) useful in the composition (I).
[0286] That is, the AMPS polymer acts mainly on the reaction of the
dye. Accordingly, for the dye package, the AMPS polymer can be
added directly into the dyeing composition (A), e.g., as a mixture
with the colorant composition (I) and/or with the colorant
composition (II); or can be added into an independent chamber,
e.g., in the form of an AMPS composition (B), separate from the
dyeing composition (A).
[0287] For the use as an AMPS composition (B) independently from
the dyeing composition (A), the composition (B) can comprise any
component known in the field of cosmetics benefiting the stability
of the AMPS polymer.
[0288] Accordingly, the present invention can advantageously
provide a dyeing package kit, comprising:
[0289] a dyeing composition (A) according to the present invention
placed in chamber 1; and
[0290] an AMPS composition (B) according to the present invention
placed in chamber 2 separate from chamber 1.
[0291] Use
[0292] The invention also relates to the use of the dye package as
described above for dyeing keratin fibers, in particular the
hair.
[0293] Another subject of the invention is a process for dyeing
human keratin fibers, in particular the hair, using the dye package
as described above.
[0294] According to a preferred embodiment, the dyeing process of
the invention comprises mixing the colorant composition (I) and the
composition (II) immediately before use, and applying the mixture
obtained as described above to the keratin fibers.
[0295] More particularly, by "mixing" or a variant thereof, it is
intended to mean the action of putting the colorant composition (I)
of the present invention into a container or palm, together with
the developer composition (II) as described above, with or without
stirring them.
[0296] According to a preferred variant of the preferred
embodiment, the colorant composition (I) of the present invention
is put into a container or palm together with the developer
composition (II) as described above, without stirring them.
[0297] Irrespective of the process used and the number of
compositions used, the composition(s) described previously,
optionally mixed beforehand, are applied to wet or dry keratin
fibers.
[0298] As stated above in the portion of "Addition form of AMPS
polymers", the AMPS polymers can be provided in various forms to be
used with the colorant composition (I) and the developer
composition (II), so as to slow down the reaction of the dye. In
particular for the dye package kit described according to the
present invention: [0299] if the user does not want to slow down
the dyeing, or the stain by dye is not cared, chamber 2 may not be
used; [0300] if the user desires avoiding any stain, he/she can mix
chamber 2 with 1 before dyeing; [0301] if the user wants to
determine the use or not of chamber 2 depending on whether an
actual stain occurs, he/she can firstly use only chamber 1, and
when the dyeing composition is adhered to hand or anywhere else,
chamber 2 may be immediately applied; and [0302] if the user wants
to avoid stain, and desires rapid dyeing, he/she can apply in
advance chamber 2 onto positions on which stain may most likely
occur but should be avoided, e.g., hand.
[0303] Alternatively, if an AMPS polymer is provided together with
the colorant composition (I) an/or with developer composition (II),
e.g., being added directly into either or both of the compositions,
the dyeing process is always slowed down, comparing with a same
dyeing process except for the absence of any AMPS polymer.
[0304] The mixed compositions, including the colorant composition
(I) and the developer composition (II), and optionally the AMPS
composition, are usually left in place on the fibers for a time
generally ranging from 1 minute to 1 hour and preferably from 5
minutes to 30 minutes.
[0305] The temperature during the process is conventionally between
20 and 80.degree. C. and preferably between 20 and 60.degree. C.
After the treatment, the human keratin fibers are advantageously
rinsed with water. They may optionally be further washed with a
shampoo, followed by rinsing with water, before being dried or left
to dry.
[0306] The process may be repeated several times in order to obtain
the desired coloration.
[0307] The abovementioned dye package may also be equipped with
means allowing the delivery to the hair of the desired mixture,
such as, for example, the device described in patent FR 2 586
913.
[0308] The examples that follow are given purely as illustrations
of the present invention.

Example 3
[0313] For application, composition I-A was mixed with compositions
II-A.about.D with a weight ratio of 1:1.5, to provide mixtures A-D.
20 g of the mixtures A-D were each poured in the palm of the hair
dressers, who applied the products (mixtures A-D) immediately onto
the middle-length hair, i.e., hair length was at the shoulder. The
hair was massaged and foam was formed.
[0314] At the time of 0, 2.5, 5, 7.5 and 10 minutes, the hair was
taken a picture, respectively. As shown in FIG. 1, it was clear to
see that at each time point, the hair dyed with the mixtures
A.about.C comprising AMPS had a color lighter than that dyed with
mixture D without AMPS. That is, clear water effects were observed
for the mixture D, which represented combinations of composition
I-A with composition II-A.about.C, respectively, compared with
mixture D.
[0315] Similarly, compositions I-B and I-C, in combination with
composition II-A, were subjected to an application same as that for
composition I-A, and clear water effects were also observed.
