Abstract
The present invention relates to a series of novel glyceryl phosphobetaine compounds which are exceptional f surface active agents that provide outstanding foam and are very mild to the hair and skin. The compounds, because they contain a pendant ionizable phosphate group and a quaternary amine compound are amphoteric surfactants that is they contain both a positive and negative charge in the same molecule. These combination of properties makes these polymers ideally suited for use in personal care applications.
