Abstract

Cosmetic compositions containing in an aqueous medium an alkylgalactoside uronate and an organopolysiloxane and their use in the treatment or washing of keratinous materials. The alkylgalactoside uronate is based on formula (I): R1 is a C8-C22 alkyl; with carbon carrying the hydroxyl group being linked to the endocyclic oxygen atom; R2 is hydrogen, an alkaline metal, an alkaline-earth metal or a quaternary ammonium group.

Description

The invention relates to cosmetic compositions containing at least one anionic surfactant of alkylgalactoside uronate type and one organopolysiloxane and to their uses for treating keratinous substances.

Compositions for washing hair or the skin are generally formulated from anionic or nonionic surfactants or their mixtures, optionally in the presence of amphoteric surfactants.

It has been proposed to add silicones to these washing compositions in order to improve their cosmetic properties but the lathering ability of such compositions and the quality of the lathers are unsatisfactory.

Anionic surfactants of alkylgalactoside uronate type have already been recommended in washing compositions for the hair. They have been described in EP 0,532,370.

Compositions for washing the hair which use only these surfactants do not lead to good cosmetic properties; in particular, disentangling of wet hair is difficult and the qualities of the lathers are unsatisfactory.

The Applicant Company has just surprisingly discovered that the combination, in washing and/or treating compositions for keratinous substances, of an anionic surfactant of alkylgalactoside uronate type and of an organopolysiloxane defined below conferred greatly improved disentangling properties for wet hair on these compositions.

Moreover, the combination in accordance with the present invention makes it possible to obtain a copious, compact and very soft lather.

In addition, the Applicant Company has observed that the cosmetic compositions containing such a combination conferred good cosmetic properties, such as softness or a pleasant feel, and that they were very well tolerated by the skin.

The subject of the present invention is therefore cosmetic compositions containing at least one alkylgalactoside uronate and one organopolysiloxane defined below.

Another subject of the invention consists of the use of these compositions for treating and/or washing keratinous substances such as the hair or the skin.

Finally, another subject of the invention consists of a cosmetic treatment process for the hair or for the skin by means of the compositions of the invention; washing and treatment processes for the hair being preferred.

The cosmetic compositions according to the invention contain, in a cosmetically acceptable aqueous medium:

(A) at least one anionic surfactant of alkylgalactoside uronate type of formula:

in which:

R 1 denotes a linear or branched alkyl radical containing 8 to 22 carbon atoms,

R denotes a group

 in which the carbon carrying the hydroxyl group is connected to the endocyclic oxygen atom; R 2 being hydrogen, an alkali-metal, an alkaline-earth metal or a quaternary ammonium group which is unsubstituted or substituted by alkyl or hydroxyalkyl radicals or derived from amino acids,

(B) at least one organopolysiloxane chosen from:

(i)—organopolysiloxane oils with the exception of linear polydimethylsiloxanes with a viscosity of less than 10 −1 m 2 /s,

(ii)—organopolysiloxane gums,

(iii)—organopolysiloxane resins,

(iv)—organomodified polysiloxanes,

(v)—mixtures of linear polydimethylsiloxanes with a viscosity of less than 10 −1 m 2 /s with one or a number of compound(s) defined under (i), (ii), (iii) and (iv).

The washing compositions can be used as shampoos but also as a shower gel for washing the hair and the skin, in which case they are applied to the wet skin and hair, which are rinsed after application.

When the compositions are used for conditioning the hair, they are applied to the wet hair, after which it can either be dried or, after an exposure time of 1 to 10 minutes, rinsed with water. It is observed that the wet hair disentangles readily.
