Abstract

The invention discloses a fatty acyl amino acid polyhydroxy ester compound. The fatty acyl amino acid polyhydroxy compound is prepared from 25-50 parts by weight of fatty acyl amino acid and 20-30 parts by weight of a polyhydroxy compound under the action of a catalyst. The structure of the fatty acyl amino acid polyhydroxy ester compound contains an amino acid structure, an amide group brought byamino acid, and a plurality of hydroxyl structures brought by polyol or natural sugar alcohol or saccharides, so the compound provided by the invention has the advantages of lower irritation, lower toxicity, good biodegradability, good affinity to human bodies and the like, has a strong moisturizing function, can provide unique skin feeling, and can also relieve the irritation of other additivesto the skin. The invention also discloses a preparation method of the fatty acyl amino acid polyhydroxy ester compound. According to the preparation method, the raw materials are natural and non-irritant, operation is simple and easy, and the reaction process of dehydration condensation is easy to control.

Description

technical field [0001] The invention relates to the technical field of organic compound synthesis, in particular to a fatty acylamino acid polyhydroxy ester compound and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, people have higher and higher requirements for the functionality, experience, mildness, and safety of cosmetic raw materials. Emulsifiers and hydrophilic ester excipients in the cosmetics field , The variety, quality and quantity of thickeners have developed by leaps and bounds. Although there are many types of cosmetic emulsifiers, hydrophilic ester excipients, and thickeners, the common ones are based on fatty acid esters or fatty alcohol chains as lipophilic groups, which have a strong sticky feeling. When blended in a large amount in cosmetics, the usability and texture of the cosmetics deteriorate. In addition, in the current new cosmetics, there ...
