Abstract

The invention relates to a synthetic method of polyglycerol-10 oleate. The synthetic method sequentially comprises the following steps: (1) carrying out polymerization reaction on glycerol under catalysis of a combined catalyst A to obtain polyglycerol-10, wherein the combined catalyst A is prepared from 5-55% of NaOH, 5-55% of KOH, 5-15% of MgO and 5-25% of Al2O3; and (2) carrying out esterification reaction on polyglycerol-10 and oleic acid under catalysis of a combined catalyst B to obtain the polyglycerol-10 oleate, wherein the combined catalyst B is prepared from 5-35% of NaOH, 25-85% of KOH, 5-15% of MgO and 5-25% of Al2O3. According to the synthetic method provided by the invention, the glycerol polymerization reaction and esterification reaction efficiencies can be greatly enhanced, so that polyglycerol-10 oleate is efficiently synthesized. The yield can be improved, and the product purity is improved.

Description

technical field [0001] The invention relates to the technical field of surfactants, in particular to a method for synthesizing polyglycerol-10 oleate. Background technique [0002] In cosmetic raw materials, consumers are extremely concerned about the surfactant ingredients. Some surfactants are more irritating to the skin, especially to sensitive skin. [0003] In particular, the skin of children and infants is different from that of adults, mainly in several aspects: First, the skin metabolism of children and infants is very vigorous, but the skin is thinner, which is sensitive to environmental factors such as dryness, cold, humidity, and alkalinity. , acid and other chemical stimuli are sensitive, and their resistance is weak; secondly, the skin weight of children and infants accounts for a higher proportion of body weight, and the skin barrier function is not as perfect as that of adults, so the skin permeability is higher than that of adults. The skin absorption rate ...
