Polyglycerol-2 stearate CAS 12694-22-3

As one of the glycerol fatty acid ester series emulsifiers, the emulsification performance of polyglycerol-2 stearate is much better than that of single glycerol fatty acid ester, because polyglycerol-2 stearate has more hydrophilic hydroxyl group, and its hydrophilicity increases with the increase of glycerol polymerization degree. The lipophilicity of polyglycerin-2 stearate emulsifiers varies with the alkyl group of fatty acids, so a series of HLB values (1-20) can be obtained by changing the degree of glycerol polymerization, the type of fatty acids and the degree of esterification.
