Abstract
The present invention is related to a series of polyesters based upon the reaction of succinic acid, dimer alcohol and Guerbet alcohol. The resulting polyester is a high molecular weight product that is well tolerated by the skin and has outstanding emolliency. The Guerbet alcohol, being mono hydroxyl is a capper portion of the polymer, the dimer alcohol is a chain extender having two hydroxyl groups and the succinic acid is a diacid that reacts with the hydroxyl groups on the Guerbet and dimer alcohol to make the polyester.
