Description
[0001] The present invention relates to an oxidizing composition
intended for treating keratin fibres, comprising at least one
enzyme of 2-electron oxidoreductase type in the presence of at
least one donor for the said enzyme and at least one nonionic guar
gum, as well as to its uses for dyeing, for permanently reshaping
or for bleaching keratin fibres, in particular human hair.
[0002] It is known to dye keratin fibres, and in particular human
hair, with dye compositions containing oxidation dye precursors, in
particular para-phenylenediamines, ortho- or para-aminophenols and
heterocyclic bases which are generally referred to as oxidation
bases. Oxidation dye precursors, or oxidation bases, are colourless
or weakly coloured compounds which, when combined with oxidizing
products, can give rise to coloured compounds and dyes by a process
of oxidative condensation.
[0003] It is also known that the shades obtained with these
oxidation bases can be varied by combining them with couplers or
colour modifiers, the latter being chosen in particular from
aromatic meta-diamines, meta-aminophenols, meta-diphenols and
certain heterocyclic compounds.
[0004] The variety of compounds used as regards the oxidation bases
and the couplers allows a wide range of colours to be obtained.
[0005] The so-called "permanent" coloration obtained by means of
these oxidation dyes must moreover satisfy a certain number of
requirements. Thus it must have no toxicological drawbacks, it must
be able to give shades of the desired intensity and it must be able
to withstand external agents (light, bad weather, washing,
permanent-waving, perspiration, rubbing).
[0006] The dyes must also be able to cover white hair and, lastly,
they must be as unselective as possible, i.e. they must give the
smallest possible colour differences along the same length of
keratin fibre, which may in fact be differently sensitized (i.e.
damaged) between its tip and its root.
[0007] The oxidation dyeing of keratin fibres is generally carried
out in alkaline medium, in the presence of hydrogen peroxide.
However, the use of alkaline media in the presence of hydrogen
peroxide has the drawback of causing appreciable degradation of the
fibres, as well as considerable bleaching of the keratin fibres,
which is not always desirable.
[0008] The oxidation dyeing of keratin fibres can also be carried
out using oxidizing systems other than hydrogen peroxide, such as
enzymatic sytems. Thus, it has already been proposed to dye keratin
fibres, in particular in patent application EP-A-0,310,675, with
compositions comprising an oxidation dye precursor in combination
with enzymes such as pyranose oxidase, glucose oxidase or uricase,
in the presence of a donor for the said enzymes. Although being
used under conditions which do not result in degradation of the
keratin fibres which is comparable to that caused by the dyes used
in the presence of hydrogen peroxide, these dye formulations
nevertheless lead to colorations which are still insufficient, both
as regards the homogeneity of the colour distributed along the
fibre ("unison") and as regards the chromaticity (luminosity), the
dyeing power and the resistance to the various aggressive factors
to which the hair may be subjected.
[0009] It is known that the most common technique for obtaining a
permanent reshaping of the hair consists, in a first stage, in
opening the keratin -S-S-disulphide (cysteine) bonds using a
composition containing a suitable reducing agent (reduction step)
followed, after having rinsed the head of hair thus treated, by
reconstituting, in a second stage, the said disulphide bonds by
applying to the hair, which has been placed under tension
beforehand (rollers and the like), an oxidizing composition
(oxidation step, also known as the fixing step) so as finally to
give to the hair the desired shape. This technique thus makes it
equally possible either to make the hair wavy or to straighten it
or to remove its curliness. The new shape given to the hair by a
chemical treatment such as above is remarkably long-lasting and in
particular resists the action of washing with water or shampoos, as
opposed to simple standard techniques for temporary reshaping, such
as hairsetting.
[0010] The reducing compositions which may be used in order to
carry out the first step of a permanent-waving operation generally
contain, as reducing agents, sulphites, bisulphites,
alkylphosphines or, preferably, thiols. Among the thiols, those
commonly used are cysteine and the various derivatives thereof,
cysteamine and the derivatives thereof, thiolactic acid or
thioglycolic acid, the salts thereof and the esters thereof, in
particular glyceryl thioglycolate.
[0011] As regards the oxidizing compositions needed to carry out
the fixing step, use is usually made in practice of compositions
based on aqueous hydrogen peroxide, sodium bromate or persalts such
as sodium perborate, which have the drawback of being liable to
damage the hair.
[0012] The problem of the technique of the permanent-waving
operations known to date is that their application to the hair
induces long-term adverse changes in the quality of the hair. The
essential causes of these adverse changes in the quality of the
hair are a reduction in its cosmetic properties, such as its sheen
and its feel, and degradation of its mechanical properties, more
particularly degradation of its mechanical strength due to swelling
of the keratin fibres during the rinsing between the reduction step
and the oxidation step, which can also be reflected by an increase
in its porosity. The hair is weakened and can become brittle during
subsequent treatments such as blow-drying.
[0013] The same problem of adverse changes in keratin fibres is
encountered during processes for bleaching the hair.
[0014] It is known that the permanent reshaping or bleaching of
keratin fibres can also be carried out under milder conditions
using oxidizing systems other than hydrogen peroxide, such as
enzymatic systems. Thus, processes for the permanent reshaping or
bleaching of keratin fibres have already been proposed, in
particular in patent application EP-A-0,310,675, with compositions
comprising an enzyme such as pyranose oxidase, glucose oxidase or
uricase, in the presence of a donor for the said enzyme. Although
being used under conditions which do not result in degradation of
the keratin fibres which is comparable to that caused by
conventional permanent-waving or bleaching processes, these
oxidizing formulations nevertheless lead to results which are still
insufficient, as regards the curl hold over time, as regards the
compatibility of permanent-waved or bleached hair with subsequent
treatments, as regards the reduction of the mechanical properties
of the permanent-waved hair, in particular the reduction of the
porosity of the hair, and as regards the reduction of the cosmetic
properties such as the feel, or alternatively as regards the
uniformity of the bleaching along the keratin fibres.
[0015] The aim of the present invention is to solve the problems
mentioned above.
[0016] The Applicant has discovered, surprisingly, novel
compositions containing, as oxidizing system, at least one enzyme
of 2-electron oxidoreductase type in the presence of at least one
donor for the said enzyme and at least one nonionic guar gum, which
can constitute, in the presence of oxidation dye precursors
(oxidation bases) and optionally couplers, ready-to-use dye
formulations which lead to more homogeneous, more intense and more
chromatic colorations without giving rise to any significant
degradation, these colorations being relatively unselective and
showing good resistance to the various aggressive factors to which
the hair may be subjected.
[0017] The Applicant has also discovered, unexpectedly, that the
use, in a process for the permanent reshaping of keratin fibres, of
an oxidizing composition containing, as oxidizing system, at least
one enzyme of 2-electron oxidoreductase typein the presence of at
least one donor for the said enzyme and at least one nonionic guar
gum, makes it possible to solve the technical problems mentioned
above. In particular, this type of oxidizing composition improves
the curl hold obtained over time, substantially reduces the
porosity of permanent-waved hair and improves the compatibility of
permanent-waved hair with respect to subsequent treatments.
[0018] The Applicant has also discovered, surprisingly, that the
use, in a process for bleaching keratin fibres, of an oxidizing
composition containing, as oxidizing system, at least one enzyme of
2-electron oxidoreductase typein the presence of at least one donor
for the said enzyme and at, least one nonionic guar gum makes it
possible to solve the technical problems mentioned above, in
particular to improve the compatibility of bleached hair with
respect to subsequent treatments. This type of oxidizing
composition gives a more uniform bleaching effect on the hair and
improves the cosmetic properties, such as the feel.
[0019] These discoveries form the basis of the present
invention.
[0020] The subject of the present invention is thus, firstly, a
cosmetic and/or dermatological composition intended for treating
keratin fibres, in particular human keratin fibres and more
particularly human hair, comprising, in a support which is suitable
for keratin fibres:
[0021] (a) at least one enzyme of 2-electron oxidoreductase type in
the presence of at least one donor for the said enzyme,
[0022] (b) at least one nonionic guar gum.
[0023] The 2-electron oxidoreductase(s) used in the oxidizing
compositions in accordance with the invention can be chosen in
particular from pyranose oxidases, glucose oxidases, glycerol
oxidases, lactate oxidases, pyruvate oxidases and uricases.
[0024] According to the invention, the 2-electron oxidoreductase is
preferably chosen from uricases of animal, microbiological or
biotechnological origin.
[0025] By way of example, mention may be made of uricase extracted
from boar liver, uricase from Arthrobacter globiformis, as well as
uricase from Aspergillus flavus.
[0026] The 2-electron oxidoreductase(s) can be used in pure
crystalline form or in a form diluted in a diluent which is inert
with respect to the said 2-electron oxidoreductase.
[0027] The 2-electron oxidoreductase(s) in accordance with the
invention preferably represent(s) from 0.01 to 20% by weight
approximately relative to the total weight of the composition, and
even more preferably from 0.1 to 5% by weight approximately
relative to this weight.
[0028] According to the invention, the term donor is understood to
refer to the various substrates also necessary for the functioning
of the said 2-electron oxidoreductase(s).
[0029] The nature of the donor (or substrate) for the said enzyme
varies depending on the nature of the 2-electron oxidoreductase
used. For example, as donors for the pyranose oxidases, mention may
be made of D-glucose, L-sorbose and D-xylose; as a donor for the
glucose oxidases, mention may be made of D-glucose; as donors for
the glycerol oxidases, mention may be made of glycerol and
dihydroxyacetone; as donors for the lactate oxidases, mention may
be made of lactic acid and its salts; as donors for the pyruvate
oxidases, mention may be made of pyruvic acid and its salts; and
lastly, as donors for the uricases, mention may be made of uric
acid and its salts.
[0030] The donor(s) (or substrate(s)) used in accordance with the
invention preferably represent from 0.01 to 20% by weight
approximately relative to the total weight of the composition in
accordance with the invention, and even more preferably from 0.1 to
5% approximately relative to this weight.
[0031] According to the invention, unmodified or. chemically
modified nonionic guar gums can be used.
[0032] The unmodified nonionic guar gums are, for example, the
products sold under the name Vidogum GH 175 by the company
Unipectine and under the name Jaguar C by the company Meyhall.
[0033] The nonionic guar gums which can be used according to the
invention are preferably modified with C.sub.1-C.sub.6 hydroxyalkyl
groups.
[0034] Among the hydroxyalkyl groups, mention may be made, for
example, of hydroxymethyl, hydroxyethyl, hydroxypropyl and
hydroxybutyl groups.
[0035] These guar gums are well known in the state of the art and
can be prepared, for example, by reacting corresponding alkene
oxides, such as, for example, propylene oxides, with the guar gum,
so as to obtain a guar gum modified with hydroxypropyl groups.
[0036] 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.
[0037] 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.
[0038] The concentration of nonionic guar gum can range from 0.01
to 10% by weight approximately relative to the total weight of the
composition, and preferably between 0.1 and 5% approximately.
[0039] A subject of the present invention is also a ready-to-use
composition for the oxidation dyeing of keratin fibres, and in
particular human keratin fibres such as the hair, of the type
comprising, in a medium which is suitable for dyeing, at least one
oxidation base and, where appropriate, one or more couplers, which
is characterized in that it contains:
[0040] (a) at least one enzyme of 2-electron oxidoreductase type in
the presence of at least one donor for the said enzyme,
[0041] (b) at least one nonionic guar gum.
[0042] The nature of the oxidation base(s) used in the ready-to-use
dye composition is not a critical factor. They can be chosen, in
particular, from para-phenylenediamines, double bases,
para-aminophenols, ortho-aminophenols and heterocyclic oxidation
bases.

[0112] The oxidation base(s) in accordance with the invention
preferably represent(s) from 0.0005 to 12% by weight approximately
relative to the total weight of the ready-to-use dye composition,
and even more preferably from 0.005 to 6% by weight approximately
relative to this weight.
[0113] The couplers which can be used are those used conventionally
in oxidation dye compositions, i.e. meta-phenylenediamines,
meta-aminophenols and meta-diphenols, mono- or polyhydroxylated
naphthalene derivatives, sesamol and its derivatives and
heterocyclic compounds such as, for example, indole derivatives,
indoline derivatives, benzimidazole derivatives, benzomorpholine
derivatives, sesamol derivatives, pyrazoloazole derivatives,
pyrroloazole derivatives, imidazoloazole derivatives,
pyrazolo-pyrimidine derivatives, pyrazoline-3,5-dione derivatives,

derivatives, thiazoloazole S-oxide derivatives and thiazoloazole
S,S-dioxide. derivatives, and the addition salts thereof with an
acid.
[0114] These couplers can be chosen in particular from
2-methyl-5-aminophenol, 5-N-(.beta.-hydroxyethyl)
amino-2-methylphenol, 3-aminophenol, 1,3-dihydroxybenzene,
1,3-dihydroxy-2-methylbenzene, 4-chloro-1,3-dihydroxy-benzene,

with an acid.
[0115] When they are present, these couplers preferably represent
from 0.0001 to 10% by weight approximately relative to the total
weight of the ready-to-use dye composition, and even more
preferably from 0.005 to 5% by weight approximately relative to
this weight.
[0116] In general, the addition salts with an acid which can be
used in the context of the dye compositions of the invention
(oxidation bases and couplers) are chosen in particular from the
hydrochlorides, hydrobromides, sulphates, tartrates, lactates and
acetates.
[0117] The dye composition of the invention can also contain, in
addition to the oxidation bases defined above and the optional
combined couplers, direct dyes to enrich the shades with glints.
These direct dyes can be chosen in particular from nitro dyes, azo
dyes or anthraquinone dyes.
[0118] The subject of the invention is also a process for dyeing
keratin fibres, and in particular human. keratin fibres such as the
hair, using the ready-to-use dye composition as defined above.
[0119] According to this process, at least one ready-to-use dye
composition as defined above is placed on the fibres, for a period
which is sufficient to develop the desired coloration, after which
the fibres are rinsed, optionally washed with shampoo, rinsed again
and dried.
[0120] The time required to develop the coloration on the keratin
fibres is generally beteen 3 and 60 minutes and even more precisely
between 5 and 40 minutes.
[0121] According to a first specific embodiment of the invention,
the process includes a first step which consists in separately
storing, on the one hand, a composition (A) comprising, in a medium
which is suitable for dyeing, at least one oxidation base and
optionally at least one coupler as defined above, and, on the other
hand, a composition (B) containing, in a medium which is suitable
for dyeing, at least one enzyme of 2-electron oxidoreductase type
in the presence of at least one donor for the said enzyme and at
least one nonionic guar gum containing at least one hydrophilic
unit and at least one fatty chain, and then in mixing them together
at the time of use, before applying this mixture to the keratin
fibres.
[0122] According to another specific embodiment of the invention,
the nonionic guar gum is incorporated into composition (A).
[0123] Another subject of the invention is a multi-compartment
dyeing device or "kit" or any other multi-compartment packaging
system, a first compartment of which contains composition (A) as
defined above and a second compartment of which contains
composition (B) as defined above. These devices can be equipped
with means for applying the desired mixture to the hair, such as
the devices described in patent FR-2,586,913 in the name of the
Applicant.
[0124] A subject of the present invention is also a, novel process
for treating keratin substances, in particular the hair, in order
to obtain a permanent reshaping of this hair, in particular in the
form of permanent-waved hair, this process comprising the following
steps: (i) a reducing composition is applied to the keratin
substance to be treated, the keratin substance being placed under
mechanical tension before, during or after the said application,
(ii) the keratin substance is optionally rinsed, (iii) an oxidizing
composition as defined above is applied to the optionally rinsed
keratin substance, (iv) the keratin substance is optionally rinsed
again.
[0125] The first step (i) of this process consists in applying a
reducing composition to the hair. This application is carried out
lock by lock or all at once.
[0126] The reducing composition comprises, for example, at least
one reducing agent, which can be chosen in particular from
thioglycolic acid, cysteine, cysteamine, glyceryl thioglycolate,
thiolactic acid or thiolactic or thioglycolic acid salts.
[0127] The usual step for placing the hair under tension in a shape
corresponding to the desired final shape for this hair (for example
curls) can be carried out by any suitable means, in particular
mechanical means, known per se for maintaining the hair under
tension, such as, for example, rollers, curlers and the like.
[0128] The hair can also be shaped without the aid of external
means, simply with the fingers.
[0129] Before carrying out the following optional rinsing step
(ii), the hair onto which the reducing composition has been applied
should, conventionally, be left to stand for a few minutes,
generally between 5 minutes and one hour, preferably between 10 and
30 minutes, so as to give the reducing agent enough time to act
correctly on the hair. This waiting phase preferably takes place at
a temperature ranging from 35.degree. C. to 45.degree. C., while
preferably also protecting the hair with a hood.
[0130] In the optional second step of the process (step (ii)), the
hair impregnated with the reducing composition is then rinsed
thoroughly with an aqueous composition.
[0131] Next, in a third step (step (iii)), the oxidizing
composition of the invention is applied to the hair thus rinsed,
with the aim of fixing the new shape given to the hair.
[0132] As in the case of the application of the reducing
composition, the hair onto which the oxidizing composition has been
applied is then conventionally, left for a standing or waiting
phase lasting a few minutes, generally between 3 and 30 minutes,
preferably between 5 and 15 minutes.
[0133] If the hair was maintained under tension by external means,
these means (rollers, curlers or the like) can be removed from the
hair before or after the fixing step.
[0134] Lastly, in the final step of the process according to the
invention (step (iv)), which is also optional, the hair impregnated
with the oxidizing composition is rinsed thoroughly, generally with
water.
[0135] Hair which is soft and easy to disentangle is finally
obtained. The hair is wavy.
[0136] The oxidizing composition according to the invention can
also be used in a process for bleaching keratin fibres, and in
particular the hair.
[0137] The bleaching process according to the invention comprises a
step of applying an oxidizing composition according to the
invention to the keratin fibres in the presence or absence of an
auxiliary oxidizing agent. Conventionally, a second step of the
bleaching process according to the invention is a step of rinsing
the keratin fibres.
[0138] The medium which is suitable for the keratin fibres (or the
support) for the ready-to-use dye compositions and for the
oxidation compositions used for the permanent reshaping or
bleaching of keratin- fibres in accordance with the invention
generally consists of water or of a mixture of water and at least
one organic solvent in order to dissolve the compounds which would
not be sufficiently soluble in water. By way of organic solvent,
mention may be made, for example, of C.sub.1-C.sub.4 alkanols such
as ethanol and isopropanol; glycerol; glycols and glycol ethers
such as 2-butoxyethanol, propylene glycol, propylene glycol
monomethyl ether, diethylene glycol monoethyl ether and monomethyl
ether, and aromatic alcohols such as benzyl alcohol or
phenoxyethanol, similar products and mixtures thereof.
[0139] The solvents can be present in proportions preferably of
between 1 and 40% by weight approximately relative to the total
weight of the dye composition, and even more preferably between 5
and 30% by weight approximately.
[0140] The pH of the ready-to-use dye compositions and of the
oxidizing compositions used for the permanent reshaping or
bleaching of the keratin fibres in accordance with the invention is
chosen such that the enzymatic activity of the 2-electron
oxidoreductase is not adversely affected. It is generally between 5
and 11 approximately, and preferably between 6.5 and 10
approximately. It can be adjusted to the desired value using
acidifying or basifying agents usually used for dyeing keratin
fibres.
[0141] 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 or lactic acid, and
sulphonic acids.
[0142] Among the basifying agents, mention may be made, by way of
example, of aqueous ammonia, alkaline carbonates, alkanolamines
such as mono-, di- and triethanolamines, 2-methyl-2-aminopropanol
and derivatives thereof, sodium hydroxide, potassium hydroxide and
the compounds of formula (V) below: 6
[0143] in which W is a propylene residue optionally substituted
with a hydroxyl group or a C.sub.1-C.sub.4 alkyl radical; R.sub.13,
R.sub.14, R.sub.15 and R.sub.16, which may be identical or
different, represent a hydrogen atom or a C.sub.1-C.sub.4 alkyl or
C.sub.1-C.sub.4 hydroxyalkyl radical.
[0144] The ready-to-use dye compositions and the oxidizing
compositions for the permanent reshaping or bleaching of keratin
fibres in accordance with the invention can also contain various
adjuvants used conventionally in compositions for dyeing,
permanently reshaping or bleaching the hair, such as anionic,
cationic, nonionic, amphoteric or zwitterionic surfactants or
mixtures thereof, anionic, cationic, nonionic, amphoteric or
zwitterionic polymers or mixtures thereof, inorganic or organic
thickeners, antioxidants, enzymes other than the 2-electron
oxidoreductases used in accordance with the invention, such as, for
example, peroxidases, penetration agents, sequestering agents,
fragrances, buffers, dispersing agents, conditioners such as, for
example, silicones, film-forming agents, preserving agents and
opacifiers.
[0145] Needless to say, a person skilled in the art will take care
to select this or these optional complementary compound(s) such
that the advantageous properties intrinsically associated with the
compositions in accordance with the invention are not, or are not
substantially, adversely affected by the addition or additions
envisaged.
[0146] The ready-to-use dye compositions and the oxidizing
compositions used for the permanent reshaping or bleaching of
keratin fibres in accordance with the invention can be in various
forms, such as in the form of liquids, creams or gels, which are
optionally pressurized, or in any other form which is suitable for
dyeing, permanently reshaping or bleaching keratin fibres, and in
particular human hair.
[0147] In the case of a ready-to-use dye composition, the oxidation
dyes(s) and the 2-electron oxido-reductase(s) are present in the
said composition, which must be free of oxygen gas, so as to avoid
any premature oxidation of the oxidation dye(s).
[0148] Concrete examples illustrating the invention will now be
given.
[0149] In the text hereinabove and hereinbelow, except where
otherwise mentioned, the percentages are expressed on a weight
basis.
[0150] The examples which follow illustrate the invention without
being limiting in nature.
