Polyesters based upon dimer acid in personal care
View Patent ↗The present invention is related to the cosmetic utilization of a series of polyesters based upon the reaction of dimer 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 dimer acid is a diacid that reacts with the hydroxyl groups on the Guerbet and dimer alcohol to make the polyester.

15. A process of claim 2 wherein a is 13 and b is 17.
16. A process of claim 2 wherein a is 17 and b is 19.
17. A process of claim 1 wherein said effective conditioning concentration ranges from 0.5% to 5% by weight.
18. A process of claim 1 wherein said effective conditioning concentration ranges from 1.0% to 5% by weight.
