Abstract
Cosmetic compositions containing in an aqueous medium an alkylgalactoside uronate and a synthetic hydrocarbon oil and their use in the treatment or washing of keratinous materials. The alkylgalactoside uronate is based on formula (I): ##STR1## R.sub.1 is a C.sub.8 -C.sub.22 alkyl; R is (i) or (ii): >CH--CH(OH)--CO.sub.2 R.sub.2 (i) --CH(OH)--CH--CO.sub.2 R.sub.2 (ii) with the carbon carrying the hydroxyl group being linked to the endocyclic oxygen atom; R.sub.2 is hydrogen, an alkaline metal, an alkaline-earth metal or a quaternary ammonium group.
Claims18
Cosmetic composition comprising, in a cosmetically acceptable aqueous medium:
- (A) between 0.5 and 30% by weight of at least one anionic surfactant of alkylgalactoside uronate type of formula:
- ##STR9## in which:
- R.sub.1 denotes a linear or branched C.sub.8 -C.sub.22 alkyl radical
- R denotes a group
- (i) CH--CH(OH)--CO.sub.2 R.sub.2 or
- (ii) --CH(OH)--CH--CO.sub.2 R.sub.2, in which the carbon carrying the hydroxyl group is connected to the endocyclic oxygen atom;
- R.sub.2 denotes a hydrogen, an alkali metal or an alkaline-earth metal or a quaternary ammonium group which is unsubstituted or substituted by alkyls or hydroxyalkyls;
- and
- (B) between 0.1 and 20% by weight of at least one synthetic hydrocarbon oil selected from the group consisting of:
- hydrogenated and non-hydrogenated polyisobutenes;
- and
- hydrogenated and non-hydrogenated polydecenes.
