Abstract: The present invention deals with the certain novel esters derived from a specific 36 carbon diol and fatty acids, which unlike other esters are surprisingly stable to hydrolysis and consequently of interest in high and low pH applications.

Abstract: The invention relates to a series of novel quaternized silicone fluorinated dimethicone copolyol phosphates. This class of compounds are outstandingly mild detergents and emulsifiers that provide breathable barriers when applied to hair and skin. These emulsions allow for delivery of barriers to the skin that allow for the passage of water and air through the barrier, but do not allow for the passage of oils. The compounds of the present invention are prepared by reacting a the aqueous salt a fluoro dimethicone copolyol phosphate disclosed in U.S. Pat. No. 6,087,517 with a 3-chloro-2-hydoxypropyl-quaternary compound.
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.
