Abstract

A composition for cosmetic treatment of keratinous materials comprising in a cosmetically acceptable medium, at least a volatile silicone, at least a silicone surfactant and at least a cationic surfactant in a concentration strictly higher than 0.5 wt. % relative to the composition total weight, selected among primary, secondary or tertiary fatty amine salts, optionally polyoxyalkylenated, quaternary ammonium salts and their mixtures. The composition comprises at least an amount of oils containing at least the volatile silicone in a concentration not more than 20 wt.% relative to the composition total weight. A method for cosmetic treatment of keratinous materials is also disclosed.

Claims

1. A composition for cosmetic treatment of keratinous materials, in the form of a water-in-oil emulsion, comprising, in a cosmetically acceptable medium, at least one volatile silicone, at least one silicone surfactant wherein the silicone surfactant is present in a quantity between 0.01 and 3% by weight relative to the total weight of the composition and at least one cationic surfactant in a concentration wherein the cationic surfactant is present in a quantity between 0.5 and 10% by weight relative to the total weight of the composition, wherein the at least one volatile silicone is a cyclic volatile silicone comprising 3 to 7 silicon atoms, wherein the volatile silicone is present in a quantity between 5 and 20% by weight relative to the total weight of the composition;

wherein the cationic surfactant is a quaternary ammonium salt, the quaternary ammonium salt being;

a salt having the following general formula (VI);

2. The composition for cosmetic treatment of keratinous materials as claimed in Claim 1, wherein the cationic surfactant is present in a quantity between 0.8 and 8% by weight relative to the total weight of the composition.

3. The composition for cosmetic treatment of keratinous materials as claimed in claim 2, wherein the cationic surfactant is present in a quantity between 1 and 5% by weight relative to the total weight of the composition.

4. The composition for cosmetic treatment of keratinous materials as claimed in Claim 1, wherein the volatile silicone is present in a quantity between 8 and 15% by weight relative to the total weight of the composition.

5. The composition for cosmetic treatment of keratinous materials as claimed in Claim 1, wherein the silicone surfactant is a compound of formula (II) in which at least one of the following conditions are satisfied:

a) c is equal to 2 or 3;

b) R₁ is a methyl group;

c) R₅ represents a hydrogen atom, a methyl group or an acetyl group;

d) a is from 1 to 25;

e) b is from 0 to 25;

f) n is from 0 to 100; and

g) p is from 1 to 20.

6. The composition for cosmetic treatment of keratinous materials as claimed in Claim 1, wherein the silicone surfactant is present in a quantity between 0.2 and 3% by weight relative to the total weight of the composition.

7. The composition for cosmetic treatment of keratinous materials as claimed in claim 1, wherein the cosmetically acceptable medium is water or a mixture of water and a cosmetically acceptable solvent.

8. The composition for cosmetic treatment of keratinous materials as claimed in claim 7, wherein the cosmetically acceptable solvent is a C₁-C₄ lower alcohol, polyol, polyol ether, C₅-C₁₀ alkane, C_3-4 ketone, C₁-C₄ alkyl acetate, dimethoxyethane, diethoxyethane, or mixtures thereof.

9. The composition for cosmetic treatment of keratinous materials claimed in claim 1, further comprising an additive which is a cationic, anionic, non-ionic or amphoteric polymer;

modified or unmodified non-volatile silicone;

associative or non-associative, anionic, amphoteric, zwitterionic, non-ionic or cationic, natural or synthetic polymeric thickener;

non-polymeric thickener;

sugar, nacrant, opacifier, sun filter, perfume, dye, organic or mineral particle, preservative, or pH stabiliser.

10. A process for cosmetic treatment of keratinous materials, comprising applying a composition for cosmetic treatment of keratinous materials as claimed in claim 1 to the keratinous materials.

11. The process for cosmetic treatment of keratinous material as claimed in claim 10, wherein the composition is a hair conditioner.
