Overview	The emulsifying properties of polyglycerol -2 oleate are much superior to those of monoglycerides, the reason is that polyglycerol esters have more hydrophilic hydroxyl groups; And its hydrophilicity increases with the increase of the degree of polymerization of glycerol, and the lipophilicity varies with the different fatty acid alkyl groups, so by changing the degree of polymerization of polyglycerol (2-10 Poly), fatty acid types (oleic acid, stearic acid, lauric acid, octanodecanoic acid, lactic acid) and esterification degree, can get a series of HLB value (1~20), from lipophilic to hydrophilic polyglycerol ester products with different properties, to be suitable for various special uses.
preparation	preparation method of polyglycerol -2 oleate:(1) after the fatty acid mixture containing oleic acid and urea are dissolved in an organic solvent, cooling is performed to separate and remove the precipitated crystals. (2) the fatty acid mixture in the partially dissolved organic solvent solution is recrystallized and filtered to obtain crystals. (3) the obtained crystals were subjected to acid hydrolysis to obtain refined oleic acid. Glycidol is added to the purified oleic acid, or the Oleic acid is esterified with polyglycerol, or the oleic acid and polyglycerol are subjected to a dehydration reaction.
