(57) [Summary] [Objective] To provide a surfactant capable of producing a completely solubilized product or a stable emulsion in the food, cosmetic, pharmaceutical and industrial fields. [Structure] Low molecular weight polyglycerin reactant by liquid chromatography using a column packed with an alkaline earth metal salt of a gel-type cation exchange resin having a polystyrene skeleton having a cross-linking degree of more than 8% and not more than 12% The polyglycerin fatty acid ester obtained by the first step of removing the reaction product to obtain polyglycerin and the second step including the subsequent esterification with a fatty acid is suitable for the production of a completely solubilized product or a stable emulsion. Now, it is possible to manufacture products that were previously impossible. |
