Abstract

Abstract New amphoteric compounds which contain two basic groups, at least one of which is a quaternary ammonium group, and an anionic group of the carboxylic type and one or two lipophile chains. These compounds have excellent cationic characteristics while being less, and in some cases nonirritating to the mucous membrane of the eye.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 186 words
A cosmetic composition for hair comprising in aqueous solution 1 to 10% by weight of at least one compound corresponding to the following formula: [A.sup.+-- CH.sub.2 CONH -- (CH.sub.2).sub.n -- B] X.sup.- in which: n is a whole number equal to 2 or 3 A represents a radical of the formula: ##STR45## in which R 1 is a radical selected from the group consisting of: methyl, cetyl and a radical derived from copra fatty acid having 6 - 18 carbon atoms; R 2 and R 3 are selected from the group consisting of: alkyl and hydroxy-alkyl radicals having 1 to 3 carbon atoms; B is a radical selected from the group consisting of: ##STR46## in which R 4 is selected from the group consisting of alkyl and hydroxy alkyl radicals having 1 - 3 carbon atoms and a radical derived from copra fatty acid having 6 - 18 carbon atoms; R 5 is a lower alkyl radical having from 1 to 3 carbon atoms, and M represents an alkali metal selected from the group consisting of potassium and sodium, and X - is a chloride ion.
Claim 2
Dependent Claim 186 words
A cosmetic composition for hair comprising in aqueous solution 1 to 10% by weight of at least one compound corresponding to the following formula: [A.sup.+-- CH.sub.2 CONH -- (CH.sub.2).sub.n -- B] X.sup.- in which: n is a whole number equal to 2 or 3 A represents a radical of the formula: ##STR45## in which R 1 is a radical selected from the group consisting of: methyl, cetyl and a radical derived from copra fatty acid having 6 - 18 carbon atoms; R 2 and R 3 are selected from the group consisting of: alkyl and hydroxy-alkyl radicals having 1 to 3 carbon atoms; B is a radical selected from the group consisting of: ##STR46## in which R 4 is selected from the group consisting of alkyl and hydroxy alkyl radicals having 1 - 3 carbon atoms and a radical derived from copra fatty acid having 6 - 18 carbon atoms; R 5 is a lower alkyl radical having from 1 to 3 carbon atoms, and M represents an alkali metal selected from the group consisting of potassium and sodium, and X - is a chloride ion.
