Abstract
The present invention is directed to a series of glycerin based polymers that have been designed to have very specific substitution patterns, herein referred to as regiospecific substitution (RSS). The attachment of terminal mono-functional silicone polymers engineered polyesters of glycerin results in heretofore unrecognized products. The unique properties include lower surface tension, better spreadability and a dry skin feel, all of which cannot be attained without the use of a terminal silicone. Incorporation of silicone into the terminal position requires a very specific synthesis regime to establish the sought after regiospecificity.
