Abstract
The present invention relates to a series of novel silicone ester quaternary polymers which are substantive to fiber and provide outstanding softening properties to various fibers, hair and skin. The compounds of the present invention are prepared by the esterification of a terminal hydroxyl group which is present on a silicone polymer with monochloroacetic acid, and in a subsequent step, reacting the chloro ester so produced with a tertiary amine to produce the desired quaternary compound.
