Abstract
Cosmetic compositions for treating the hair, nails and skin are described which contain, in a solvent medium, at least one amphoteric polymer of betainised dialkylaminoalkyl (meth)acrylate or dialkylaminoalkyl(meth)acrylamide, containing at least units of the formula: ##STR1## in which R.sub.1 denotes a hydrogen atom or a methyl group, R.sub.2 denotes an alkylene group having 1 to 4 carbon atoms, Y denotes O or NH and R.sub.3 and R.sub.4 independently of one another denote hydrogen or alkyl having 1 to 4 carbon atoms, and at least one cationic derivative.
Claims21
A composition for the treatment of hair to improve the liveliness, shine, body, stiffness, and combout properties of the hair and to impart softness to the hair, said composition comprising, in a solvent medium, at least one amphoteric polymer of betainised dialkylaminoalkyl (meth) acrylate or dialkylaminoalkyl (meth) acrylamide containing units of the formula:
- ##STR16## in which R.sub.1 denotes a hydrogen atom or a methyl group, R.sub.2 denotes an alkylene group having 1 to 4 carbon atoms, Y denotes O or NH and R.sub.3 and R.sub.4 independently denote a hydrogen atom or an alkyl radical having 1 to 4 carbon atoms and at least one cationic surface-active agent selected from the group consisting of quaternary ammonium salts, an alkylamine acetate, alkylamine hydrochloride, an alkylamidodiethylamine that is soluble on neutralisation, a fatty diamine giving rise to a soluble salt, a condensation product of a fatty acid with hydroxyethylethylenediamine, an ethylhydroxymethylalkyloxazoline and a cationic protein hydrolysate.
A shampoo composition for the hair which comprsies, in a solvent medium, an amount of about 3 to 50% of a surface-active agent, at least one amphoteric polymer of betainised dialkylaminoalkyl (meth)acrylate or dialkylaminoalkyl (meth)acrylamide containing units of the formula:
- ##STR20## in which R.sub.1 denotes a hydrogen atom or a methyl group, R.sub.2 denotes an alkylene group having 1 to 4 carbon atoms, Y denotes O or NH and R.sub.3 and R.sub.4 independently denote a hydrogen atom or an alkyl radical having 1 to 4 carbon atoms;
- and
- at least one cationic surface-active agent selected from the group consisting of quaternary ammonium salts, an alkylamine acetate, alkylamine hydrochloride, an alkylamidodiethylamine that is soluble on neutralisation, a fatty diamine giving rise to a soluble salt, a condensation product of a fatty acid with hydroxyethylethylenediamine, an ethylhydroxymethylakyloxazoline and a cationic protein hydrolysate.
A composition for conditioning the hair which comprises, in a solvent medium, at least one amphoteric polymer of betainised dialkylaminoalkyl (meth)acrylate or dialkylaminoalkyl (meth)acrylamide, containing units of the formula:
- ##STR21## in which R.sub.1 denotes a hydrogen atom or a methyl group, R.sub.2 denotes an alkylene group having 1 to 4 carbon atoms, Y denotes O or NH and R.sub.3 and R.sub.4 independently denote a hydrogen atom or an alkyl radical having 1 to 4 carbon atoms;
- and
- at least one cationic surface-active agent selected from the group consisting of quaternary ammonium salts, an alkylamine acetate, alkylamine hydrochloride, an alkylamidodiethylamine that is soluble on neutralization, a fatty diamine giving rise to a soluble salt, a condensation product of a fatty acid with hydroxyethylethylenediamine, an ethylhydroxymethylalkyloxazoline and a cationic protein hydrolysate.
