Abstract

A transparent composition for cosmetic treatment of keratinous materials comprising, in a cosmetically acceptable medium, at least a compound selected among polyols and mineral electrolytes, at least a volatile silicone, at least a siliconized surfactant, and at least a cationic surfactant in a concentration strictly higher than 0.5 wt. % relative to the composition total weight. The proportions of the polyols and mineral electrolytes are such that the (polyol and/or electrolyte)/oil ratio is not less than 2, the oil comprising at least the volatile silicone. A method for cosmetic treatment of keratinous materials using the transparent composition is also disclosed.

Claims

1. A transparent composition for the cosmetic treatment of keratinous materials in the form of a water-in-oil emulsion, comprising, in a cosmetically acceptable medium, at least one compound which is a polyol or mineral electrolyte, at least one volatile silicone in a quantity of between 5 and 20% by weight relative to the total weight of the composition, at least one silicone surfactant wherein the silicone surfactant is present in a quantity of between 0.01 and 10% by weight relative to the total weight of the composition, and at least one cationic surfactant wherein the cationic surfactant is present in a quantity of between 0.5 and 10% by weight relative to the total weight of the composition, wherein the ratio (polyol and/or electrolyte)/oil is greater than or equal to 2, wherein the at least one volatile silicone is a cyclic volatile silicone comprising 3 to 7 silicon atoms,

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

a salt of formula (VI):

2. Transparent composition for the cosmetic treatment of keratinous materials according to claim 1, wherein the ratio of (polyol and/or electrolyte)/oil is between 2 and 10.

3. Transparent composition for the cosmetic treatment of keratinous materials according to claim 2, wherein the ratio of (polyol and/or electrolyte)/oil is between 2 and 5.
