Abstract
The present invention relates to a series of novel silicone phosphobetaines which are high foaming low irritation surface active agents that are substantive to fiber and hair. The compounds, because they contain a pendant ionizable phosphate group and a quatarnary amine compound are amphoterics that is they contain both a positive and negative charge in the same 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. In addition, these compounds are non volatile and nonirritating. These combination of properties makes these polymers ideally suited for use in personal care applications.
