Abstract
The present invention is directed to a series of polyester compounds made from the reaction of (a) a difunctional hydroxy compound, specifically polyoxyalkylene glycols, (b) a difunctional carboxylic acid, specifically dimer acid and hydrogenated dimer acid, and (c) a capping carboxylic acid, which only contains one acid group. These compounds are very well suited to the preparation of products for the personal care market.
