Abstract
The present invention is aimed at a series of novel glycerin polyesters that provide desired aesthetics and structure in cosmetic formulation. These glycerin polymers are synthesized by polycondensation polymerization, in the presence of a monofunctional monomer or terminal group. By carefully choosing the groups the properties can be dramatically altered. The mono-functional alcohols, being only able to react in one position, can only be located on the polymer chain ends. This provides very unique polymer structure and morphology. These regiospecific polyesters will have very unique physical properties and have a wide variety of solubilities. Furthermore, by the incorporation of a co-monomer will produce a copolymer with drastically different solubilities and aesthetics.
