Polyglycerol-2 stearate is much better than that of monoglycerol fatty acid ester, because polyglycerol-2 stearate has more There are many hydrophilic hydroxyl groups, and its hydrophilicity increases with the increase of glycerol polymerization degree. The lipophilicity of polyglycerol-2 stearate emulsifier varies with fatty acid alkyl groups. Therefore, by changing the glycerol polymerization degree , fatty acid types and esterification degrees, a series of HLB values (1-20) can be obtained.
