Claims
1. A composition for the oxidation dyeing of keratin fibers,
comprising, in a medium suitable for dyeing, a) at least one
oxidation dye; b) at least one fatty alcohol; c) at least one
associative polymer; and d) at least one compound chosen from fatty
acid esters and metal oxides.
Description
[0001] This application claims benefit of U.S. Provisional
Application No. 60/502,967, filed Sep. 16, 2003.
[0002] Disclosed herein is a composition for the oxidation dyeing
of keratin fibers, for example of human keratin fibers, such as the
hair, comprising at least one oxidation dye, at least one fatty
alcohol, at least one associative polymer and at least one compound
chosen from fatty acid esters and metal oxides.
[0003] It is known practice to dye keratin fibers, and in
particular human hair, with dye compositions comprising oxidation
dye precursors, generally known as "oxidation bases", such as
ortho- and para-phenylenediamines, ortho- and para-aminophenols,
and heterocyclic bases.
[0004] Oxidation dye precursors are compounds that may initially be
uncolored or only weakly colored, which may develop their hair
dyeing power in the presence of oxidizing agents, leading to the
formation of colored compounds. The formation of these colored
compounds may result either from an oxidative condensation of the
"oxidation bases" with themselves or from an oxidative condensation
of the "oxidation bases" with coloration modifiers, or "couplers",
which may be present in the dye compositions used in oxidation
dyeing and may be, for example, meta-phenylenediamines,
meta-aminophenols, meta-diphenols, and certain heterocyclic
compounds.
[0005] The variety of molecules that may be used, which comprise on
the one hand the "oxidation bases" and on the other hand the
"couplers", may allow a wide range of colors to be obtained.
[0006] Compositions which comprise oxidation dyes and are mixed
before use with an oxidizing agent may be provided in the form of
water-based creams, which may comprise fatty alcohols and
occasionally soaps. These creams may have a high fatty alcohol
content in order to ensure the consistency and stability of the
medium.
[0007] It has been noted by the present inventors, however, that
this high content of fatty alcohols may lead to a change in
viscosity in the dyeing composition over time, which may be
manifested in a reduction in the ease of mixing with the oxidizing
agent or in an impairment of the usage qualities, such as for
example elimination on rinsing.
[0008] However, after researching the question, the present
inventors have found that oxidation dye compositions comprising at
least one oxidation dye, at least one fatty alcohol, at least one
associative polymer, and at least one compound chosen from fatty
acid esters and metal oxides have a satisfactory consistency and a
viscosity which may be stable over time without the need to
increase the concentration of fatty alcohols.
[0009] Accordingly, disclosed herein is a composition for the
oxidation dyeing of keratin fibers, for example human keratin
fibers, such as the hair, comprising, in a medium suitable for
dyeing, [0010] a) at least one oxidation dye; [0011] b) at least
one fatty alcohol; [0012] c) at least one associative polymer; and
[0013] d) at least one compound chosen from fatty acid esters and
metal oxides.
[0014] Another embodiment relates to a ready-to-use composition for
the dyeing of keratin fibers which comprises at least one oxidizing
agent, at least one oxidation dye, at least one fatty alcohol, at
least one associative polymer, and at least one compound chosen
from fatty acid esters and metal oxides.
[0015] As used herein, the expression "ready-to-use composition"
means a composition intended for application as it is to the
keratin fibers; that is to say, it may be stored as it is before
use or may result from the mixing of at least two compositions.
[0016] Also disclosed herein is a process for the oxidation dyeing
of keratin fibers, for example human keratin fibers such as the
hair, comprising applying to the fibers a composition (A)
comprising, in a medium suitable for dyeing, at least one oxidation
dye, at least one fatty alcohol, at least one associative polymer,
and at least one compound chosen from fatty acid esters and metal
oxides, the color being developed at alkaline, neutral or acidic
pH, by means of a composition (B) comprising at least one oxidizing
agent, which is mixed with the composition (A) at the time of use
or which is applied sequentially before or after composition (A),
optionally with intermediate rinsing.
[0017] Also disclosed herein are multi-compartment dyeing devices
or multi-compartment kits for the oxidation dyeing of keratin
fibers, for example human keratin fibers such as the hair. A device
according to one embodiment may comprise a first compartment
comprising at least one oxidation dye, at least one fatty alcohol,
at least one associative polymer, and at least one compound chosen
from fatty acid esters and at metal oxides, and a second
compartment comprising at least one oxidizing agent.
[0018] Other features, aspects, subjects and advantages will emerge
even more clearly on reading the description and the examples that
follow.
[0019] The at least one fatty acid ester may be chosen from
monoesters, diesters and triesters obtained from reacting linear or
branched, saturated or unsaturated monoacids or diacids having 8 to
30 carbon atoms, which are optionally hydroxylated, with saturated
or unsaturated, linear, branched or cyclic monoalcohols or polyols
having 2 to 100 carbon atoms and having 1 to 30 hydroxyl
groups.
[0020] The linear or branched, saturated or unsaturated monoacids
or diacids may, for example, be chosen from stearic acid, palmitic

and which are sold by the company Amerchol, and the products
Crodacel QM, Crodacel QL, which is a C.sub.12 alkyl, and Crodacel
QS, which is a C.sub.18 alkyl, and which are sold by the company
Croda.
[0097] The polyacrylates comprising amine side groups, which may be
quaternized or non-quaternized, may have, for example, steareth 20
hydrophobic groups, such as polyoxyethylenated (20) stearyl
alcohol.
[0098] Examples that may be mentioned of polyacrylates comprising
amine side chains include the polymers 8781-121B or 9492-103
provided by the company National Starch.
[0099] The cationic associative polyurethanes according to certain
embodiments may be chosen from cationic associative amphiphilic
polyurethanes, which may be water-soluble or water-dispersible.
[0100] As used here, the term "water-soluble" or "soluble in water"
in relation to the associative polyurethanes signifies that these
polymers have a solubility in water at ambient temperature of at
least 1% by weight; that is to say that, up to this concentration,
no precipitate can be detected by the naked eye and the solution is
clear and homogeneous.
[0101] As used herein, polyurethanes which are "water-dispersible"
or "dispersible in water" are polymers which, when suspended in
water, spontaneously form droplets having an average size, as
measured by light scattering on a Coulter-type apparatus, ranging
from 5 nm to 600 nm, for example from 5 nm to 500 nm.
[0102] The family of cationic amphiphilic polyurethanes according
to certain embodiments disclosed herein has been described by the
Applicant in French Patent Application No. 0 009 609; it may be
represented by the general formula (Ia) below:
F--X--(P).sub.a-[L-(Y).sub.m].sub.r-L'-(P').sub.p--X'--F' (Ia) in
which:
[0103] F and F', which may be identical or different, are chosen
from hydrophobic groups and a hydrogen atom;
[0104] X and X', which may be identical or different, are chosen
from groups comprising an amine function optionally having at least
one of hydrophobic groups and groups L'';
[0105] L, L', and L'', which may be identical or different, are
chosen from groups derived from diisocyanate;
[0106] P and P', which may be identical or different, are chosen
from groups comprising an amine function optionally bearing at
least one hydrophobic group;
[0107] Y is chosen from hydrophilic groups;
[0108] r is an integer ranging from 1 to 100, such as from 1 to 50,
or 1 to 25; and
[0109] a, m, and p, which may be identical or different, range from
0 to 1000; and
[0110] wherein the molecule comprises at least one protonated or
quaternized amine function and at least one hydrophobic group.
[0111] In one embodiment of polyurethanes, the only hydrophobic
groups are the groups F and F' at the chain ends.
[0112] One family of cationic amphiphilic polyurethanes may
correspond to formula (Ia) described above is as follows:
[0113] F and F' are each independently chosen from hydrophobic
groups,
[0114] X and X' each represent a group L'',
[0115] a and p range from 1 to 1000, and
[0116] L, L', L'', P, P', Y, and m have the meanings given
above.
[0117] Another family of cationic amphiphilic polyurethanes may be
the one corresponding to formula (Ia) above in which:
[0118] F and F' are each independently chosen from hydrophobic
groups,
[0119] X and X' each represent a group L'',
[0120] a and p are 0, and
[0121] L, L', L'', Y, P, P', and m have the meanings given
above.
[0122] The fact that a and p are 0 means that these polymers do not
comprise units derived from a monomer comprising at least one amine
function, incorporated into the polymer during the
polycondensation. The protonated amine functions of these
polyurethanes may result from the hydrolysis of excess isocyanate
functions, at the chain end, followed by alkylation of the primary
amine functions formed with alkylating agents comprising at least
one hydrophobic group, i.e., compounds of the type FQ or F'Q, in
which F and F' are as defined above and Q denotes a leaving group
such as those chosen from halides and sulphates.
[0123] Yet another family of cationic amphiphilic polyurethanes is
the one corresponding to formula (Ia) above in which:
[0124] F and F' are both independently chosen from hydrophobic
groups,
[0125] X and X' are both independently chosen from groups
comprising at least one quaternary amine,
[0126] a and p are 0, and
[0127] L, L', Y, P, P', and m have the meanings given above.
[0128] The number-average molecular mass of the cationic
associative polyurethanes may range from 400 to 500,000, for
example from 1,000 to 400,000, or for example from 1,000 to
300,000.
[0129] As used herein, the expression "hydrophobic group" means a
radical or polymer comprising at least one saturated or
unsaturated, linear or branched hydrocarbon-based chain, which may
comprise at least one heteroatom such as P, O, N, and S, or a
radical comprising a perfluoro or silicone chain. When the
hydrophobic group is a hydrocarbon-based radical, it may have at
least 10 carbon atoms, for example 10 to 30 carbon atoms, or for
example 12 to 30 carbon atoms or 18 to 30 carbon atoms. For
example, the hydrocarbon-based group may be derived from a
monofunctional compound.
[0130] By way of example, the hydrophobic group may be derived from
a fatty alcohol such as stearyl alcohol, dodecyl alcohol, and decyl
alcohol. It may also denote a hydrocarbon-based polymer such as,
for example, polybutadiene.
[0131] When X and/or X' denote a group comprising a tertiary or
quaternary amine, X and/or X' may represent one of the following
formulae: ##STR3## in which: [0132] R.sub.2 is chosen from linear
and branched alkylene radicals having from 1 to 20 carbon atoms,
optionally comprising at least one of saturated rings, unsaturated
rings, and arylene radicals, wherein at least one of the carbon
atoms is optionally replaced with a heteroatom chosen from N, S, O
and P; [0133] R.sub.1 and R.sub.3, which may be identical or
different, are chosen from linear and branched C.sub.1-C.sub.30
alkyls, alkenyl radicals, and aryl radicals, wherein at least one
of the carbon atoms is optionally replaced with a heteroatom chosen
from N, S, O, and P; and [0134] A.sup.- is a physiologically
acceptable counter-ion.
[0135] According to one aspect of the present disclosure, the
groups L, L' and L'' are chosen from a group of formula: ##STR4##
in which: [0136] Z is chosen from oxygen atoms, sulfur atoms, and
--NH groups; and [0137] R.sub.4 is chosen from linear and branched
alkylene radicals having from 1 to 20 carbon atoms, optionally
comprising at least one of saturated rings, unsaturated rings, and
arylene radicals, wherein at least one of the carbon atoms is
optionally replaced with a heteroatom chosen from N, S, O, and
P.
[0138] The groups P and P' comprising an amine function may
represent at least one of the following formulae: ##STR5## in
which: [0139] R.sub.5 and R.sub.7 have the same meanings as R.sub.2
defined above; [0140] R.sub.6, R.sub.8, and R.sub.9 have the same
meanings as R.sub.1 and R.sub.3 defined above; [0141] R.sub.10 is
chosen from linear and branched, saturated and unsaturated alkylene
groups which optionally comprising at least one heteroatom chosen
from N, O, S, and P; and [0142] A.sup.- is a physiologically
acceptable counter-ion.
[0143] As regards the meaning of Y, as used herein the term
"hydrophilic group" means a polymeric or non-polymeric
water-soluble group.
[0144] By way of example, when Y is not a polymer, Y may be chosen
from, by way of non-limiting example, ethylene glycol, diethylene
glycol, and propylene glycol.
[0145] When Y is a hydrophilic polymer, in accordance with one
embodiment, mention may be made, for example, of polyethers,
sulphonated polyesters, sulphonated polyamides, and mixtures of
these polymers. The hydrophilic compound may be a polyether, or for
example a poly(ethylene oxide) or poly(propylene oxide).
[0146] The cationic associative polyurethanes of formula (Ia)
according to certain embodiments may be formed from diisocyanates
and from various compounds with functional groups comprising labile
hydrogen. The functional groups comprising labile hydrogen may be
chosen from alcohols, primary amines, secondary amines, and thiol
functional groups giving, after reaction with diisocyanate
functional groups, polyurethanes, polyureas, and polythioureas,
respectively. The term "polyurethanes" as used herein encompasses
these three types of polymers, namely polyurethanes, polyureas, and
polythioureas, and also copolymers thereof.
[0147] A first type of compound involved in the preparation of the
polyurethane of formula (Ia) is a compound comprising at least one
unit comprising at least one amine functional group. This compound
may be multifunctional, and the compound may be difunctional, that
is to say that, according to one embodiment, this compound
comprises two labile hydrogen atoms derived, for example, from
hydroxyls, primary amines, secondary amines, or thiol functional
groups. A mixture of multifunctional and difunctional compounds in
which the percentage of multifunctional compounds is low may also
be used.
[0148] As mentioned above, this compound may comprise more than one
unit comprising at least one amine functional group. In this case,
it may be a polymer that repeats the unit comprising at least one
amine functional group.
[0149] Compounds of this type may be chosen from one of the
following formulae: HZ-(P).sub.a-ZH HZ-(P').sub.p-ZH in which Z, P,
P', a, and p are as defined above.
[0150] Examples of compounds comprising at least one amine
functional group that may be mentioned include
N-methyldiethandlamine, N-tert-butyidiethanolamine, and
N-sulphoethyldiethanolamine.
[0151] The second compound involved in the preparation of the
polyurethane of formula (Ia) is a diisocyanate corresponding to the
formula: O.dbd.C.dbd.N--R.sub.4--N.dbd.C.dbd.O in which R.sub.4 is
as defined above.
[0152] By way of example, mention may be made of methylenediphenyl
diisocyanate, methylenecyclohexane diisocyanate, isophorone
diisocyanate, toluene diisocyanate, naphthalene diisocyanate,
butane diisocyanate, and hexane diisocyanate.
[0153] A third compound involved in the preparation of the
polyurethane of formula (Ia) may be a hydrophobic compound intended
to form the terminal hydrophobic groups of the polymer of formula
(Ia).
[0154] This compound comprises a hydrophobic group and a functional
group comprising at least one labile hydrogen, for example
hydroxyls, primary amines, secondary amines, and thiol functional
groups.
[0155] By way of example, this compound may be a fatty alcohol such
as stearyl alcohol, dodecyl alcohol, and decyl alcohols. When this
compound comprises a polymeric chain, it may be, for example,
.alpha.-hydroxylated hydrogenated polybutadiene.
[0156] The hydrophobic group of the polyurethane of formula (Ia)
may also result from the quaternization reaction of the tertiary
amine of the compound comprising at least one tertiary amine unit.
Thus, the hydrophobic group may be introduced via the quaternizing
agent. This quaternizing agent may be a compound of the type FQ or
F'Q, in which F and F' are as defined above and Q is chosen from
leaving groups such as halides and sulphates.
[0157] The cationic associative polyurethane may also comprise a
hydrophilic block. This block is provided by a fourth type of
compound involved in the preparation of the polymer. This fourth
compound may be multifunctional. The fourth compound may, for
example, be difunctional. It is also possible to have a mixture in
which the percentage of multifunctional compounds is low.
[0158] The functional groups comprising at least one labile
hydrogen may be chosen from alcohols, primary amines, secondary
amines, and thiol functional groups. This fourth compound may be a
polymer terminated at the chain ends with one of these functional
groups comprising at least one labile, hydrogen.
[0159] By way of example, when the fourth compound is not a
polymer, it may be chosen from, by way of non-limiting example,
ethylene glycol, diethylene glycol, and propylene glycol.
[0160] When the fourth compound is a hydrophilic polymer, mention
may be made, for example, of polyethers, sulphonated polyesters,
sulphonated polyamides, and mixtures of these polymers. The
hydrophilic compound may be chosen from polyethers, or for example,
poly(ethylene oxide) and poly(propylene oxide).
[0161] The hydrophilic group Y in formula (Ia) is optional.
Specifically, the units comprising a quaternary amine or protonated
functional group may suffice to provide the solubility or
water-dispersibility required for this type of polymer in an
aqueous solution.
[0162] Although the presence of hydrophilic group Y is optional,
cationic associative polyurethanes comprising such a group may be
used in certain embodiments.
[0163] The said cationic associative polyurethanes may be
water-soluble or water-dispersible.
[0164] The cationic poly(vinyllactam)polymers according to the
invention comprise: [0165] a) at least one monomer chosen from
vinyllactam monomers and alkylvinyllactam monomers; [0166] b) at
least one monomer chosen from structures (Ib) and (IIb) below:

[0176] x is an integer ranging from 1 to 100, and
[0177] Z.sup.- is chosen from organic and mineral acid anions,
[0178] with the proviso that: [0179] at least one of the
substituents R13, R14, R15, and R18 is chosen from linear
C.sub.9-C.sub.30 alkyl radicals and branched C.sub.9-C.sub.30 alkyl
radicals, [0180] if m or n is not zero, then q is equal to 1, and
[0181] if m or n are equal to zero, then p' or q is equal to 0.
[0182] The cationic poly(vinyllactam)polymers according to certain
embodiments may be crosslinked or non-crosslinked, and may also be
block polymers.
[0183] For example, the counter-ion Z.sup.- of the monomers of
formula (Ib) may be chosen from halide ions, phosphate ions,
methosulphate ions, and tosylate ions.
[0184] As another example, R13, R14, and R15, which may be
identical or different, are chosen from a hydrogen atom, linear
C.sub.1-C.sub.30 alkyl radicals, and branched C.sub.1-C.sub.30
alkyl radicals.
[0185] As yet another example, the monomer b) is a monomer of
formula (Ib) for which m and n are equal to zero.
[0186] The vinyllactam or alkyvinyllactam monomer may be a compound
of structure (IVb): ##STR7## in which:
[0187] s is an integer ranging from 3 to 6,
[0188] R19 is chosen from a hydrogen atom and C.sub.1-C.sub.5 alkyl
radicals, and
[0189] R20 is chosen from a hydrogen atom and C.sub.1-C.sub.5 alkyl

[0190] with the proviso that at least one of the radicals R19 and
R20 is a hydrogen atom.
[0191] For example, the monomer (IVb) may be vinylpyrrolidone.
[0192] The cationic poly(vinyllactam)polymers according to certain
embodiments may also comprise at least one additional monomer,
which may be cationic or non-ionic.
[0193] As compounds that may be used according to certain
embodiments, mention may be made of the following terpolymers
comprising at least: [0194] (a)- a monomer of formula (IVb), [0195]
(b)- a monomer of formula (Ib) in which p is equal to 1, q is equal
to 0, R13 and R14, which may be identical or different, are chosen

[0197] For example, terpolymers comprising, on a weight basis, from
40% to 95% of monomer (a), 0.1% to 55% of monomer (c), and 0.25% to
50% of monomer (b) may be used.

lamidopropylammonium tosylate and chloride terpolymers.
[0200] The weight-average molecular mass of the cationic
poly(vinyllactam)polymers according to this embodiment may range
from 500 to 20,000,000. It may, for example, range from 200,000 to
2,000,000, or for example from 400,000 to 800,000.
[0201] Among the cationic amphiphilic polymers according to this
embodiment, mention may also be made of acrylic terpolymers as
described in patent application EP 1 090 623 and which comprise:
[0202] from 5% to 80% by weight, such as from 15% to 70% by weight

is based on the total weight of the monomers comprising the
terpolymer.
[0211] Acrylate monomers (a) that may be used comprise

[0213] The monomers (c) may be copolymerizable ethylenic
unsaturated surfactant monomers obtained by condensing at least one

[0214] Examples of monomers (c) that may be used correspond to

[0215] Acrylic terpolymers may thus be chosen from acrylic
terpolymers comprising acrylates, amino(meth)acrylates, and
C.sub.10-C.sub.30 alkyl itaconate, polyoxyethylenated with 20 mol
of ethylene oxide.
[0216] Conventional methods for preparing these acrylic terpolymers
are known to those skilled in the art. Such methods include
solution polymerization, precipitation polymerization, and emulsion
polymerization. Terpolymers in accordance with certain embodiments
and methods for preparing them are described for example in patent
applications EP A 0 824 914 and EP A 0 825 200.
[0217] Among these terpolymers, a STRUCTURE.RTM. 7 Plus polymer
sold by the company National Starch may be used, which comprises
acrylates, amino(meth)acrylates, and C.sub.10-C.sub.30 alkyl
itaconate, polyoxyethylenated with 20 mol of ethylene oxide, in the
form of an aqueous dispersion comprising 20% active material.
[0218] In addition to these monomers, the terpolymers can comprise
other monomers which allow the said terpolymers to be crosslinked.
These monomers may be used in relatively low proportions, of up to

[0220] The associative polymers according to certain embodiments
may also be chosen from amphoteric associative polymers.
[0221] As used herein, the term "amphoteric polymers" generally
denotes polymers which comprise units K and M randomly distributed
in the polymer chain, where K denotes a unit derived from a monomer
comprising at least one basic nitrogen atom and M denotes a unit
deriving from an acidic monomer comprising at least one carboxylic
or sulphonic groups, or else K and M may denote groups derived from
zwitterionic carboxybetaine or sulphobetaine monomers;
[0222] K and M may also denote a cationic polymer chain comprising
at least one of primary, secondary, tertiary, and quaternary amine
groups, in which at least one of the amine groups bears a
carboxylic or sulphonic group linked via a hydrocarbon-based
radical, or else K and M form part of a chain of a polymer
comprising an .alpha.,.beta.-dicarboxylic ethylene unit in which
one of the carboxylic groups has been made to react with a
polyamine comprising at least one of primary and secondary amine
groups.
[0223] The amphoteric polymers used according to certain
embodiments may further comprise at least one fatty chain having 8
to 30 carbon atoms, and may be chosen, for example, from polymers
derived from polyaspartic acid and comprising at least one fatty
chain having 8 to 30 carbon atoms, such as those: [0224] described
and prepared in patent application EP 0 767 191, the content of
which is incorporated by reference herein. Such polymers may be
prepared in conventional manner by reacting polysuccinimide (PSI)
with fatty-chain (C.sub.8-C.sub.24) amines in a solvent medium in
the presence or absence of a basic catalyst such as, for example,
aliphatic tertiary amines, followed by amphoterization of the
resultant product by reaction with a halogenated organic acid.
[0225] Among the C.sub.8-C.sub.24 fatty-chain amines which are

and in leaving the said compositions to act for an exposure time
ranging from 1 to 60 minutes and then in rinsing the fibers, and
then optionally in washing the fibers with shampoo, then rinsing
the fibers again and drying them.
