ABSTRACT:
The present invention relates to a series of novel silicone proteins which are high substantive to fiber and hair. The compounds contain both a silicone portion and protein portion in a covalent bone one molecule. Since the compounds of the present invention are high molecular weight silicone polymers, they have a high degree of oxidative stability, even at elevated temperatures and are nonirritating to skin and eyes. The proteins of the present invention plate out on and form a film on the surface of hair skin and textile fibers. In addition, these compounds are non volatile and exhibit a inverse cloud point. These combination of properties makes these polymers ideally suited for use in personal care applications.
The compounds of the invention having a pendant amphoteric group is represented by the following formula; ##STR1## wherein R is ##STR2## a is an integer from 0 to 200; b is an integer from 0 to 200;
