Definitions

  • the subject of the present invention is a composition for dyeing or lightening human keratin fibres, comprising a high content of fatty substances, a mixture of specific oxyethylenated non-ionic surfactants, a basifying agent, a persalt and hydrogen peroxide.
  • the invention also relates to a dyeing process using said composition, and to multicompartment devices.
  • oxidation dyeing or permanent dyeing. More particularly, this form of dyeing uses one or more oxidation dyes, usually one or more oxidation bases optionally combined with one or more couplers.
  • oxidation bases are chosen from ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds. These oxidation bases are colourless or weakly coloured compounds which, when combined with oxidizing products, can give access to coloured entities.
  • the shades obtained with these oxidation bases are often varied by combining them with one or more couplers, these couplers being chosen in particular from aromatic meia-diamines, meia-aminophenols, meia-diphenols and certain heterocyclic compounds, such as indole compounds.
  • direct dyes which are coloured and colouring molecules having an affinity for the fibres.
  • the direct dyes generally used are chosen from nitrobenzene, anthraquinone, nitropyridine, azo, methine, azomethine, xanthene, acridine, azine and triarylmethane direct dyes. The presence of such compounds enables the colouration obtained to be further enriched with tints or enables the chromaticity of the colouration obtained to be increased.
  • Oxidation dyeing processes thus consist in using, with these dyeing compositions, a composition comprising at least one oxidizing agent, generally hydrogen peroxide, under alkaline pH conditions in the vast majority of cases.
  • This oxidizing agent is, inter alia, to reveal the colouration, via an oxidative condensation reaction between the oxidation dyes.
  • Oxidation dyeing must moreover satisfy a certain number of requirements. Thus, it must be free of toxicological drawbacks, it must enable shades to be obtained in the desired intensity and it must show good resistance to external attacking factors such as light, bad weather, washing, permanent waving, perspiration and rubbing.
  • the dyes must also be able to cover white hair and, finally, they must be as unselective as possible, i.e. they must produce the smallest possible colour differences along the same keratin fibre, which generally comprises areas that are differently sensitized (i.e. damaged) from its end to its root.
  • compositions obtained must also have good mixing and application properties, and in particular good rheological properties so as not to run down the face, onto the scalp or beyond the areas that it is proposed to dye, when they are applied.
  • aqueous compositions comprising at least one oxidizing agent, under alkaline pH conditions in the vast majority of cases.
  • This oxidizing agent is to degrade the melanin of the hair, which, depending on the nature of the oxidizing agent present, leads to more or less pronounced lightening of the fibres.
  • the aim of the present invention is to obtain novel compositions for the dyeing and/or lightening of keratin fibres, which do not have the drawbacks of the prior art. More particularly, the aim of the present invention is to obtain novel dyeing and/or lightening compositions which are very effective in terms of colouration, in particular in terms of coverage of white hairs, of level of power or strength of colouration, of selectivity, and of quality of the uniformity of the dyeing, and are easy to mix and to apply, which limits the olfactory problems on application while at the same time detrimentally modifying the keratin fibres as little as possible.
  • OE oxyethylenated
  • OE non-ionic surfactant comprising at least 10 OE units
  • the total amount of fatty substances in the composition being greater than or equal to 50% by weight relative to the total weight of said composition.

Description

COMPOSITION RICH IN FATTY SUBSTANCES COMPRISING HYDROGEN PEROXIDE, A PERSALT AND OXYETHYLENATED SURFACTANTS
The subject of the present invention is a composition for dyeing or lightening human keratin fibres, comprising a high content of fatty substances, a mixture of specific oxyethylenated non-ionic surfactants, a basifying agent, a persalt and hydrogen peroxide.
The invention also relates to a dyeing process using said composition, and to multicompartment devices.
Among the methods for dyeing human keratin fibres, such as the hair, mention may be made of oxidation dyeing or permanent dyeing. More particularly, this form of dyeing uses one or more oxidation dyes, usually one or more oxidation bases optionally combined with one or more couplers.
In general, oxidation bases are chosen from ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds. These oxidation bases are colourless or weakly coloured compounds which, when combined with oxidizing products, can give access to coloured entities.
The shades obtained with these oxidation bases are often varied by combining them with one or more couplers, these couplers being chosen in particular from aromatic meia-diamines, meia-aminophenols, meia-diphenols and certain heterocyclic compounds, such as indole compounds.
The variety of molecules used as oxidation bases and couplers allows a wide range of colours to be obtained.
It is also possible to add to these compositions direct dyes, which are coloured and colouring molecules having an affinity for the fibres. The direct dyes generally used are chosen from nitrobenzene, anthraquinone, nitropyridine, azo, methine, azomethine, xanthene, acridine, azine and triarylmethane direct dyes. The presence of such compounds enables the colouration obtained to be further enriched with tints or enables the chromaticity of the colouration obtained to be increased.
Oxidation dyeing processes thus consist in using, with these dyeing compositions, a composition comprising at least one oxidizing agent, generally hydrogen peroxide, under alkaline pH conditions in the vast majority of cases. The role of this oxidizing agent is, inter alia, to reveal the colouration, via an oxidative condensation reaction between the oxidation dyes. Oxidation dyeing must moreover satisfy a certain number of requirements. Thus, it must be free of toxicological drawbacks, it must enable shades to be obtained in the desired intensity and it must show good resistance to external attacking factors such as light, bad weather, washing, permanent waving, perspiration and rubbing. The dyes must also be able to cover white hair and, finally, they must be as unselective as possible, i.e. they must produce the smallest possible colour differences along the same keratin fibre, which generally comprises areas that are differently sensitized (i.e. damaged) from its end to its root.
The compositions obtained must also have good mixing and application properties, and in particular good rheological properties so as not to run down the face, onto the scalp or beyond the areas that it is proposed to dye, when they are applied.
Finally, the colourations must, as far as is possible, respect the integrity of the keratin fibres and give said fibres the best possible cosmetic properties.
Many attempts have been made in the field of hair dyeing in order to improve the dyeing properties, for example using adjuvants. However, the choice of these adjuvants is difficult in so far as they must improve the dyeing properties of dye compositions without harming the other properties of these compositions. In particular, these adjuvants must not harm the stability of the compositions, the keratin fibre lightening properties, the application properties of the colouration or the cosmetic properties of the dyed fibres.
As regards processes for lightening keratin fibres, use is made of aqueous compositions comprising at least one oxidizing agent, under alkaline pH conditions in the vast majority of cases. The role of this oxidizing agent is to degrade the melanin of the hair, which, depending on the nature of the oxidizing agent present, leads to more or less pronounced lightening of the fibres.
In parallel with the lightening of the fibres, there is also a risk of degradation of these fibres and of their cosmetic properties.
The aim of the present invention is to obtain novel compositions for the dyeing and/or lightening of keratin fibres, which do not have the drawbacks of the prior art. More particularly, the aim of the present invention is to obtain novel dyeing and/or lightening compositions which are very effective in terms of colouration, in particular in terms of coverage of white hairs, of level of power or strength of colouration, of selectivity, and of quality of the uniformity of the dyeing, and are easy to mix and to apply, which limits the olfactory problems on application while at the same time detrimentally modifying the keratin fibres as little as possible. These aims and others are achieved by the present invention, one subject of which is thus a composition for dyeing and/or lightening keratin fibres, comprising:
- at least one fatty substance,
- at least one oxyethylenated (OE) non-ionic surfactant comprising a number of OE units ranging from 1 to 9, and at least one oxyethylenated
(OE) non-ionic surfactant comprising at least 10 OE units, the weight ratio of the amount of oxyethylenated non-ionic surfactant(s) comprising at least 10 OE units to the amount of oxyethylenated non-ionic surfactant(s) comprising a number of OE units ranging from 1 to 9, being greater than or equal to 1 ,
- at least one basifying agent,
- at least one persalt and
- hydrogen peroxide,
the total amount of fatty substances in the composition being greater than or equal to 50% by weight relative to the total weight of said composition.
The invention also relates to a process for dyeing or lightening human keratin fibres, comprising the application of the abovementioned composition to the keratin fibres. A subject of the invention is likewise a three-compartment device comprising:
in a first compartment, a composition (A) comprising:
- at least one fatty substance,
- at least one oxyethylenated (OE) non-ionic surfactant comprising a number of OE units ranging from 1 to 9, and at least one oxyethylenated (OE) non-ionic surfactant comprising at least 10 OE units, the weight ratio of the amount of oxyethylenated non-ionic surfactant(s) comprising at least 10 OE units to the amount of oxyethylenated non-ionic surfactant(s) comprising a number of OE units ranging from 1 to 9, being greater than or equal to 1 ,
- at least one basifying agent,
- at least one persalt and
- hydrogen peroxide,
in a second compartment, a composition (B) comprising at least hydrogen peroxide and preferably at least one fatty substance and
in a third compartment, a composition (C) comprising at least one persalt, the total amount of fatty substances in the ready-to-use composition resulting from mixing the compositions (A)+(B)+(C) being greater than or equal to 50% by weight relative to the total weight of said mixture composition.
Other characteristics and advantages of the invention will emerge more clearly on reading the description and the examples that follow.

alkylpolyglycoside carboxylic esters.
Use may be made most particularly of polyoxyalkylenated alkyl ether carboxylic acids, for instance lauryl ether carboxylic acid (4.5 OE) sold, for example, under the name Akypo RLM 45 CA from Kao.
By way of example of surfactants different from the oxyethylenated non-ionic surfactants described above, mention may be made of alkylpolyglycosides and monoglycerolated or polyglycerolated non-ionic surfactants. Monoglycerolated or polyglycerolated C8-C4o alcohols are preferably used.
In particular, the monoglycerolated or polyglycerolated C8-C40 alcohols correspond to the following formula:
RO-[CH2-CH(CH2OH)-0]m-H
in which R represents a linear or branched C8-C40 and preferably C8-C30 alkyl or alkenyl radical, and m represents a number ranging from 1 to 30 and preferably from

Mention may be made, as examples of compounds which are suitable in the context of the invention, of lauryl alcohol containing 4 mol of glycerol (INCI name: Polyglyceryl-4 Lauryl Ether), lauryl alcohol containing 1 .5 mol of glycerol, oleyl alcohol containing 4 mol of glycerol (INCI name: Polyglyceryl-4 Oleyl Ether), oleyl alcohol containing 2 mol of glycerol (INCI name: Polyglyceryl-2 Oleyl Ether), cetearyl alcohol containing 2 mol of glycerol, cetearyl alcohol containing 6 mol of glycerol, oleocetyl alcohol containing 6 mol of glycerol, and octadecanol containing 6 mol of glycerol. The alcohol may represent a mixture of alcohols in the same way that the value of m represents a statistical value, which means that, in a commercial product, several species of polyglycerolated fatty alcohols may coexist in the form of a mixture. Among the monoglycerolated or polyglycerolated alcohols, it is more particularly preferred to use the C8/Ci0 alcohol containing 1 mol of glycerol, the C10/C12 alcohol containing 1 mol of glycerol and the C12 alcohol containing 1.5 mol of glycerol.

The fumed silicas may be obtained by high-temperature hydrolysis of a volatile silicon compound in an oxyhydrogen flame, producing a finely divided silica. This process makes it possible in particular to obtain hydrophilic silicas bearing a large number of silanol groups at their surface. Such hydrophilic silicas are sold, for example, under the names Aerosil 130®, Aerosil 200®, Aerosil 255®, Aerosil 300® and Aerosil 380® by the company Degussa and Cab-O-Sil HS-5®, Cab-O-Sil EH-5®, Cab-O-Sil LM- 130®, Cab-O-Sil MS-55® and Cab-O-Sil M-5® by the company Cabot.
It is possible to chemically modify the surface of the silica via chemical reaction in order to reduce the number of silanol groups. It is possible in particular to replace silanol groups with hydrophobic groups: a hydrophobic silica is then obtained.
The hydrophobic groups may be:
- trimethylsiloxyl groups, which are obtained in particular by treating fumed silica in the presence of hexamethyldisilazane. Silicas thus treated are known as "Silica silylate" according to the CTFA (6th edition, 1995). They are sold, for example, under the references Aerosil R812® by the company Degussa and Cab-O-Sil TS- 530® by the company Cabot.
- dimethylsilyloxyl or polydimethylsiloxane groups, which are obtained in particular by treating fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas thus treated are known as Silica Dimethyl Silylate according to the CTFA (6th edition, 1995). They are sold, for example, under the references Aerosil R972® and Aerosil R974® by the company Degussa, and Cab-O- Sil TS-610® and Cab-O-Sil TS-720® by the company Cabot.
The fumed silica preferably has a particle size that may be nanometric to micrometric, for example ranging from about 5 to 200 nm.
When it is present, the inorganic thickener represents from 0.1 % to 30% by weight relative to the weight of each composition.
The compositions according to the invention may also each comprise one or more organic thickeners.
These thickeners may be chosen from fatty acid amides (coconut monoethanolamide or diethanolamide, oxyethylenated carboxylic acid monoethanolamide alkyl ether), polymeric thickeners such as cellulose-based thickeners (hydroxyethylcellulose, hydroxypropylcellulose or carboxymethylcellulose), guar gum and derivatives thereof (hydroxypropyl guar), gums of microbial origin (xanthan gum, scleroglucan gum), crosslinked homopolymers of acrylic acid or of acrylamidopropanesulfonic acid and associative polymers (polymers comprising hydrophilic regions and fatty-chain hydrophobic regions (alkyl or alkenyl comprising at least 10 carbon atoms) that are capable, in an aqueous medium, of reversibly combining with each other or with other molecules). According to one particular embodiment, the organic thickener is chosen from cellulose-based thickeners (hydroxyethylcellulose, hydroxypropylcellulose or carboxymethylcellulose), guar gum and derivatives thereof (hydroxypropyl guar), gums of microbial origin (xanthan gum, scleroglucan gum) and crosslinked homopolymers of acrylic acid or of acrylamidopropanesulfonic acid, and preferably from cellulose-based thickeners in particular with hydroxyethyl cellulose.
The content of organic thickener(s), if they are present, usually ranges from 0.01 % to 20% by weight and preferably from 0.1 % to 5% by weight, relative to the weight of each composition.
