US 5,961,964 A · Cosmetic use of cationic free radical polymers

Abstract

The present invention deals with the composition, and application of novel compounds, useful as anti-tangle, and conditioning agents for use in personal care, on hair which has been processed. By processes is meant hair which has been subjected to the process of bleaching, relaxing, permanent waving, and/or coloring. These processes make the hair raspy and degrade the properties of the hair. The properties of these novel compounds remediates the damage done to hair and leaves it more manageable and less raspy. The compounds are truly multi-functional, providing softening conditioning, and gloss to treated hair.

Dependent claims

A process for conditioning hair which comprises contacting the hair with an effective conditioning concentration of a polymer made by the free radical polymerization of:

(a) a vinyl amino compound conforming to the following structure ##STR6## wherein:
R.sup.1 and R.sup.2 are selected from methyl and ethyl;
R.sup.3 is selected from ethyl, methyl and hydrogen;
(b) in the presence of an amine conforming to the following structure;
##STR7## R.sup.4, R.sup.5 and R.sup.6 are independently selected from --(CH.sub.2 CH.sub.2 O).sub.x --(CH.sub.2 CH(CH.sub.3)O).sub.y --(CH.sub.2 CH.sub.2 O).sub.z H and CH.sub.3 ;
x, y and z are independently 0 to 5;
and (c) water, the molecular weight of said polymer ranging from 3,000 to 5,000 AMU and said effective conditioning concentration of polymer ranging from between 0.2% and 50.0% by weight.
