Oligoester

摘要

Novel polyglycerol oligoesters derived from reaction of polyglycerol with a mixture of mono and diacids and also combinations of these novel polyglycerol oligoesters with known polyol monoesters, particularly known polyglycerol monoesters are disclosed. The use of these novel polyglycerol oligoesters and combination of esters as emulsifiers, solubilisers and/or thickeners especially in personal care formulations is also disclosed.

1. A polyglycerol oligoester prepared by reacting reactants consisting essentially of:
i) a polyglycerol having from 3 to 20 glycerol units; ii) a dicarboxylic acid or cyclic anhydride of such dicarboxylic acid having from 4 to 22 carbon atoms; and iii) a linear, saturated monocarboxylic acid having from 4 to 24 carbon atoms; in a molar ratio from 1.5:1.0:0.5 to 2.5:1:1.2; wherein the polyglycerol oligoester has an HLB in the range of between 13 to 16.
