Abstract

A method of imparting improved conditioning properties to hair comprising treating the hair with a clear conditioning composition comprising an amidoamine salt, said amidoamine salt comprising an amidoamine compound having the general structural formula: ##STR1## neutralized with a suitable acid, wherein R.sub.1 is a fatty acid chain having about 11 to about 21 carbon atoms, R.sub.2 is an alkylene group having two to about four carbon atoms, R.sub.3 is hydrogen, methyl, ethyl or a hydroxyalkylene group having one to about three carbon atoms, R.sub.4 is methyl, ethyl or a hydroxyalkylene group having one to about three carbon atoms, and Y is a heterocyclic nitrogen-containing moiety, like morpholine or pyridine; and a silicone compound having at least one quaternary ammonium moiety.

Dependent claims

A clear hair conditioning composition comprising:

(a) about 0.4% to about 15% by weight of an amidoamine salt, wherein the amidoamine salt comprises:
(i) an amidoamine compound having a general structure:
##STR20## or a mixture thereof, wherein R.sub.1 is a fatty acid chain containing from about 11 to about 21 carbon atoms;
R.sub.2 is an alkylene group containing from two to about four carbon atoms;
R.sub.3 is hydrogen, a methyl group, an ethyl group or a hydroxyalkylene group containing from one to about three carbon atoms;
R.sub.4 is a methyl group, an ethyl group or a hydroxyalkylene group containing from one to about three carbon atoms;
and Y is an organic heterocyclic nitrogen-containing moiety, and
(ii) a sufficient amount of a suitable acid to neutralize the amidoamine compound and provide a composition pH of about 4 to about 7;
(b) about 0.1% to about 5% by weight of a silicone compound having at least one quaternary ammonium moiety;
and
(c) an aqueous carrier,
wherein the amidoamine compound is present in a sufficient amount to provide a clear composition, and
wherein the amidoamine compound and the silicone compound are present in a weight ratio of amidoamine compound to silicone compound of at least about 2.8 to 1.
