Description

[0001] The present invention relates to a composition for the oxidation dyeing of keratin fibres, such as human keratin fibres and further such as the hair, comprising, in a medium that is suitable for dyeing and that is free of glycerol and of cationic synthetic thickening polymer comprising at least one fatty chain, at least one oxidation dye, at least one fatty alcohol chosen from mono- and polyglycerolated fatty alcohols and at least one particular polyol.

[0002] It is known practice to dye keratin fibres, such as human hair, with dye compositions containing oxidation dye precursors, generally known as “oxidation bases.” Representative “oxidation bases” are ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic bases.

[0003] Oxidation dye precursors are compounds which are initially uncoloured or only weakly coloured and which develop their dyeing power on the hair in the presence of oxidizing agents leading to the formation of coloured compounds. The formation of these coloured compounds results 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 are generally present in the dye compositions used in oxidation dyeing and are represented by meta-phenylenediamines, meta-aminophenols and meta-diphenols, and certain heterocyclic compounds.

[0004] The variety of molecules used, which comprise on the one hand the “oxidation bases” and on the other hand, the “couplers”, allows a very wide range of colours to be obtained.

[0005] These oxidation bases and these couplers are formulated in vehicles that allow them to be applied to keratin fibres after mixing with an oxidizing agent.

[0006] These vehicles are generally aqueous and can comprise one or more surfactants, such as nonionic surfactants, that may be optionally combined with one or more solvents.

[0007] However, the Inventors have found that the systems mentioned above are not always able to produce shades that are entirely satisfactory in terms of strength, chromaticity, or staying power. The Inventors have in particular found that at least certain dye compositions of the prior art cannot achieve a sufficient strength on sensitized hair.

[0008] After considerable research conducted in this matter, the Inventors have now discovered that it is possible to obtain oxidation dye compositions that can produce strong and chromatic (luminous) shades with good staying power with respect to chemical agents (shampoo, permanent-waving agents, etc.) or natural agents (light, perspiration, etc.), thus giving a satisfactory strength on sensitized hair, by introducing into the dye composition at least one fatty alcohol chosen from mono- and polyglycerolated fatty alcohols and at least one particular polyol.

[0009] These discoveries can be present, in full or in part, in embodiments of the present invention.

[0010] One subject of the present invention is thus a composition for the oxidation dyeing of keratin fibres, such as human keratin fibres and further such as the hair, comprising, in a medium that is suitable for dyeing, at least one oxidation dye, and characterized in that:

[0011] (a) said composition further comprises at least one fatty alcohol chosen from mono- and polyglycerolated fatty alcohols and at least one polyol of formula (Ia) below:

[0012]  in which:

[0013] R1, R2, R3, and R4 are chosen from, independently of each other, a hydrogen atom, C1-C6 alkyl radicals, C1-C6 monohydroxyalkyl radicals, and C1-C6 polyhydroxyalkyl radicals;

[0014] A is chosen from linear and branched alkylene radicals containing a number of carbon atoms “n” ranging from 1 to 18, and optionally interrupted with a number of oxygen atoms “z” ranging from 0 to 9; and

[0015] m is chosen from 0 and 1;

[0016] wherein the total number of carbon atoms in both radical A and all of the substituents R1, R2, R3, and R4 is greater than or equal to 2;

[0017] wherein the molecular weight of said at least one polyol ranges (i) from 95 to 500, if m is equal to 0, or if m and n are equal to 1, or if m is equal to 1 and A is a linear alkylene radical and n is equal to 2 and z is equal to 0; or (ii) from 140 to 500, if n is greater than or equal to 2, or if m is equal to 1 and n is equal to 2 and z does not equal 0; or (iii) from 90 to 500, if m is equal to 1 and n does not equal 1 or 2 and z is equal to 0, or if m is equal to 1 and A is a branched alkylene radical and n is equal to 2 and z is equal to 0; and

[0018] (b) said composition contains no glycerol and no cationic synthetic thickening polymer comprising at least one fatty chain.

[0019] Another subject of the invention relates to a ready-to-use composition for the oxidation dyeing of keratin fibres, which comprises, in a medium that is suitable for dyeing, at least one composition as described above and at least one oxidizing agent.

[0020] For the purposes of the present invention, the expression “ready-to-use composition” is defined herein as a composition to be applied immediately to the keratin fibres. Said “ready-to-use composition” may be stored in unmodified form before use, or may result from the extemporaneous mixing of two or more compositions.

[0021] The invention is also directed towards a process for the oxidation dyeing of keratin fibres, such as human keratin fibres such as the hair, comprising applying to the fibres a composition (A) comprising, in a medium that is suitable for dyeing, at least one oxidation dye in combination with at least one fatty alcohol chosen from mono- and polyglycerolated fatty alcohols and at least one polyol of formula (Ia) below:

[0028] wherein the colour can be developed at alkaline, neutral, or acidic pH with the aid of a composition (B) comprising at least one oxidizing agent, which is mixed with composition (A) just at the time of use, or which is applied sequentially without intermediate rinsing.

[0029] A subject of the invention is also a multi-compartment dyeing device or “kit” for the oxidation dyeing of keratin fibres, such as human keratin fibres and further such as the hair, which comprises at least one first compartment comprising a composition, free of glycerol and free of cationic synthetic thickening polymer comprising at least one fatty chain, comprising at least one oxidation dye, at least one fatty alcohol chosen from mono- and polyglycerolated fatty alcohols and at least one polyol of formula (Ia) below:
