Description
[0001] The invention relates to a composition for dyeing keratin
fibers, in particular human keratin fibers such as the hair,
comprising, in a medium which is suitable for dyeing, at least one
cationic direct dye of given formula and at least one specific
thickening polymer. The invention also relates to the dyeing
processes and dyeing devices, i.e., kits, using the
composition.
[0002] Two types of dyeing may be distinguished in the haircare
sector. The first is semi-permanent or temporary dyeing, or direct
dyeing, which uses dyes capable of giving the hair a natural
coloration, a more or less pronounced color change which may
withstand shampooing several times. These dyes are also known as
direct dyes; they can be used with or without an oxidizing agent.
In the presence of an oxidizing agent, the aim is to obtain
lightening dyeing. Lightening dyeing is carried out by applying a
mixture, prepared at the time of use, of a direct dye and an
oxidizing agent to the hair, and makes it possible in particular to
obtain, by lightening the melanin in the hair, an advantageous
effect such as a unified color in the case of grey hair, or to
bring out the color in the case of naturally pigmented hair.
[0003] The second is permanent dyeing or oxidation dyeing. This is
carried out with so-called "oxidation" dyes comprising oxidation
dye precursors and couplers. Oxidation dye precursors, commonly
known as "oxidation bases", are compounds which are initially
colorless or weakly colored which develop their dyeing power on the
hair in the presence of oxidizing agents added at the time of use,
leading to the formation of colored compounds and dyes. The
formation of these colored compounds and dyes results either from
an oxidative condensation of the "oxidation bases" with themselves
or from an oxidative condensation of the oxidation bases with
coloration-modifying compounds commonly known as "couplers", which
are generally present in the dye compositions used in oxidation
dyeing.
[0004] It is known practice to add direct dyes to oxidation dyes in
order to vary the shades obtained with the said oxidation dyes or
to enrich the shades with glints. Among the cationic direct dyes
available in the sector of dyeing keratin fibers, in particular
human keratin fibers, the compounds whose structure is developed in
the text hereinbelow are already known; nevertheless, these dyes
lead to colorations which have characteristics that could still be
improved, such as the intensity, the homogeneity of the color
distributed along the fiber, in which case the coloration is said
to be too selective, and the staying power, in terms of the
resistance to the various attacking factors to which the hair may
be subjected (light, bad weather, shampooing).
[0005] After considerable research conducted in this matter, the
present inventors have discovered that it is possible to obtain
novel compositions for dyeing keratin fibers which are capable of
giving more intense and yet unselective colorations which show good
resistance to the various attacking factors to which the hair may
be subjected, by combining at least one specific thickening polymer
with at least one known cationic direct dye of the prior art, which
have the respective formulae defined below. This discovery forms
the basis of the present invention.
[0006] A first subject of the present invention is thus a
composition for dyeing keratin fibers, and in particular human

name Vidogum GH 175 by the company Unipectine and under the name
Jaguar C by the company Meyhall.
[0055] According to the present invention, it is preferred to use
nonionic guar gums modified with C.sub.1-C.sub.6 hydroxyalkyl
groups.
[0056] Among the hydroxyalkyl groups which may be mentioned, for
example, are hydroxymethyl, hydroxyethyl, hydroxypropyl and
hydroxybutyl groups. These guar gums are well known in the state of
the art and can be prepared, for example, by reacting the
corresponding alkene oxides such as, for example, propylene oxides,
with guar gum so as to obtain a guar gum modified with
hydroxypropyl groups. The degree of hydroxyalkylation, which
corresponds to the number of alkylene oxide molecules consumed by
the number of free hydroxyl functions present on the guar gum,
preferably ranges from 0.4 to 1.2.
[0057] Such nonionic guar gums optionally modified with
hydroxyalkyl groups are sold, for example, under the trade names
Jaguar HP8, Jaguar HP60 and Jaguar HP120, Jaguar DC 293 and Jaguar
HP 105 by the company Rhne-Poulenc (Meyhall) or under the name
Galactasol 4H4FD2 by the company Aqualon.
[0058] The biopolysaccharide gums of microbial origin, such as
scleroglucan gum or xanthan gum, the gums derived from plant
exudates such as gum arabic, ghatti gum, karaya gum, gum
tragacanth, carrageenan gum, agar gum and carob gum, the
hydroxyalkylcelluloses and carboxymethylcelluloses, pectins,
alginates and starches are well known to those skilled in the art
and are described in particular in the book by Robert L. Davidson
entitled "Handbook of Water soluble gums and resins" published by
McGraw Hill Book Company (1980), the disclosure of which is
specifically incorporated by reference herein.
[0059] Among these gums, the scieroglucans more particularly used
according to the present invention are represented by the products
sold under the name Actigum CS by the company Sanofi Bio Industries
and in particular Actigum CS 11, and under the name Amigel by the
company Alban Muller International. Other scleroglucans, such as
the one treated with glyoxal in French patent application No.
2,633,940, the disclosure of which is specifically incorporated by
reference herein, can also be used.
[0060] The xanthan gums more particularly used according to the
present invention are represented by the products sold under the
names Keltrol, Keltrol T, Keltrol TF, Keltrol BT, Keltrol RD and
Keltrol CG by the company Nutrasweet Kelco, or under the names
Rhodicare S and Rhodicare H by the company Rhodia Chimie.
[0061] Among the carboxyalkylcelluloses preferably used is

company Hercules, or Cellogen HP810A and Cellogen HP6HS9 by the
company Montello, or Primellose by the company Avebe.
[0062] The thickening polymers (ii) used in the compositions of the
present invention are preferably present in a proportion of from
0.01 to 10% by weight approximately, in particular in a proportion
of from 0.1 to 5% by weight approximately, relative to the total
weight of the dye composition applied to the keratin fibers.
[0063] The medium which is suitable for dyeing (or support)
generally comprises water or a mixture of water and at least one
organic solvent to dissolve the compounds which would not be
sufficiently water-soluble. As organic solvents, mention may be
made, for example, of C.sub.1-C.sub.4 lower alkanols such as
ethanol and isopropanol; aromatic alcohols such as benzyl alcohol,
as well as similar products and mixtures thereof.
[0064] The solvents can be present in proportions preferably
ranging from 1 to 40% by weight approximately relative to the total
weight of the dye composition, and even more preferably from 5 to
30% by weight approximately.
[0065] The pH of the dye composition in accordance with the
invention is generally approximately ranging from 2 to 11 and
preferably approximately ranging from 5 to 10. It can be adjusted
to the desired value using acidifying or basifying agents usually
used for dyeing keratin fibers.
[0066] Among the acidifying agents, mention may be made, by way of
example, of inorganic or organic acids such as hydrochloric acid,
orthophosphoric acid, sulphuric acid, carboxylic acids such as
acetic acid, tartaric acid, citric acid and lactic acid, and
sulphonic acids.
[0067] Among the basifying agents, mention may be made, by way of
example, of aqueous ammonia, alkaline carbonates, alkanolamines
such as mono-, di- and triethanolamine and derivatives thereof,
sodium hydroxide, potassium hydroxide and the compounds of formula
(II) below: 6
[0068] in which W is a propylene residue optionally substituted
with a hydroxyl group or a C.sub.1-C.sub.6 alkyl radical; R.sub.16,
R.sub.17, R.sub.18 and R.sub.19, which may be identical or
different, represent a hydrogen atom or a C.sub.1-C.sub.6 alkyl or
C.sub.1-C.sub.6 hydroxyalkyl radical.
[0069] In addition to the cationic direct dye(s) (i) defined above,
the dye composition in accordance with the invention can contain
one or more additional direct dyes which can be chosen, for
example, from nitrobenzene dyes, anthraquinone dyes, naphthoquinone
dyes, triarylmethane dyes, xanthene dyes and azo dyes which are
non-cationic.
[0070] When it is intended for oxidation dyeing, the dye
composition in accordance with the invention contains, in addition
to the cationic direct dye(s) (i), one or more oxidation bases
chosen from the oxidation bases conventionally used for oxidation
dyeing and among which mention may be made in particular of
para-phenylenediamines, bis(phenyl)alkylenediamines,
para-aminophenols, ortho-aminophenols and heterocyclic bases.
[0071] When they are used, the oxidation base(s) preferably
represent(s) from 0.0005 to 12% by weight approximately relative to
the total weight of the dye composition, and even more preferably
from 0.005 to 6% by weight approximately relative to this
weight.
[0072] When it is intended for oxidation dyeing, the dye
composition in accordance with the invention can also contain, in
addition to the cationic direct dye (i) and the thickening polymer
(ii) as well as the oxidation bases, one or more couplers so as to
modify the shades obtained or to enrich them with glints, by using
the cationic direct dye(s) (i) and the oxidation base(s).
[0073] The couplers which can be used in the dye composition in
accordance with the invention can be chosen from the couplers used
conventionally in oxidation dyeing and among which mention may be
made in particular of meta-phenylenediamines, meta-aminophenols,
meta-diphenols and heterocyclic couplers.
[0074] When it is (they are) present, the coupler(s) preferably
represent(s) from 0.0001 to 10% by weight approximately relative to
the total weight of the dye composition, and even more preferably
from 0.005 to 5% by weight approximately relative to this
weight.
[0075] The dye composition in accordance with the invention can
also contain various adjuvants conventionally used in compositions
for dyeing the hair, such as antioxidants, penetrating agents,
sequestering agents, fragrances, buffers, dispersing agents,
surfactants, film-forming agents, ceramides, preserving agents,
screening agents, such as sunscreens, and opacifiers.
[0076] Needless to say, a person skilled in the art will take care
to select this (these) optional complementary compound(s) such that
the advantageous properties intrinsically associated with the dye
composition in accordance with the invention are not, or are not
substantially, adversely affected by the addition(s) envisaged.
[0077] The dye composition according to the invention can be in
various forms, such as in the form of liquids, shampoos, creams or
gels or any other form which is suitable for dyeing keratin fibers,
and in particular human hair. It can be obtained by mixing, at the
time of use, a composition, which may be pulverulent, containing
the cationic direct dye(s) with a composition containing the
specific thickening polymer.
[0078] When the combination of the cationic direct dye (i) and the
thickening polymer (ii) according to the invention is used in a
composition intended for oxidation dyeing (in which case one or
more oxidation bases are used, optionally in the presence of one or
more couplers) or when it is used in a composition intended for
lightening direct dyeing, then the dye composition in accordance
with the invention also comprises at least one oxidizing agent
chosen, for example, from hydrogen peroxide, urea peroxide, alkali
metal bromates, persalts such as perborates and persulphates, and
enzymes such as peroxidases, lactases and two-electron
oxidoreductases. It is particularly preferred to use hydrogen
peroxide or enzymes.
[0079] Another subject of the invention is a process for dyeing
keratin fibers, and in particular human keratin fibers such as the
hair, using the dye composition as defined above.
[0080] According to a first variant of this dyeing process in
accordance with the invention, at least one dye composition as
defined above is applied to the fibers, for a period which is
sufficient to develop the desired coloration, after which the
fibers are rinsed, optionally washed with shampoo, rinsed again and
dried.
[0081] The time required to develop the coloration on the keratin
fibers is generally from 3 to 60 minutes and even more specifically
from 5 to 40 minutes.
[0082] According to a second variant of this dyeing process in
accordance with the invention, at least one dye composition as
defined above is applied to the fibers, for a period which is
sufficient to develop the desired coloration, without final
rinsing.
[0083] According to one specific embodiment of this dyeing process,
and when the dye composition in accordance with the invention
comprises at least one oxidation base and at least one oxidizing
agent, the dyeing process comprises a first step which comprises
separately storing, on the one hand, a composition (A1) comprising,
in a medium which is suitable for dyeing, at least one cationic
direct dye (i) as defined above and at least one oxidation base,
and, on the other hand, a composition (B1) comprising, in a medium
which is suitable for dyeing, at least one oxidizing agent, and
then in mixing them together at the time of use, after which this
mixture is applied to the keratin fibers, the composition (A1) or
the composition (B1) containing the thickening polymer (ii) as
defined above.
[0084] According to another specific embodiment of this dyeing
process, and when the dye composition in accordance with the
invention comprises at least one oxidizing agent, the dyeing
process comprises a first step which comprises separately storing,
on the one hand, a composition (A2) comprising, in a medium which
is suitable for dyeing, at least one cationic direct dye (i) as
defined above, and, on the other hand, a composition (B2)
comprising, in a medium which is suitable for dyeing, at least one
oxidizing agent, and then in mixing them together at the time of
use, after which this mixture is applied to the keratin fibers, the
composition (A2) or the composition (B2) containing the thickening
polymer as defined above.
[0085] Another subject of the invention is a multi-compartment
dyeing device, i.e., a dyeing "kit" or any other multi-compartment
packaging system, a first compartment of which comprises the
composition (A1) or (A2) as defined above and a second compartment
of which comprises the composition (B1) or (B2) as defined above.
These devices can be equipped with means for dispensing the desired
mixture onto the hair, such as the devices described in patent FR
2,586,913, the disclosure of which is specifically incorporated by
reference herein.
[0086] The examples which follow are intended to illustrate the
invention without, however, limiting its scope.
