Abstract

The invention discloses ergothioneine-lipid complex gel and a preparation method therefor and belongs to the technical field of macromolecular materials. The complex gel disclosed by the invention isprepared from the following raw materials in parts by weight: 1 part of ergothioneine, 8-20 parts of phospholipid, 0.2-1.5 parts of polyol ester, 10-20 parts of carbomer, 60-150 parts of glycerine, 10-50 parts of propylene glycol, 5-20 parts of N-trimethyl chitosan and 0.1-0.2 part of Kathon. According to the ergothioneine-lipid complex gel and the preparation method therefor, through adding the polyol ester and carrying out heated refluxing, the polyol ester promotes the phospholipid to coat the active substance ergothioneine, and the stable ergothioneine-lipid complex is formed through interaction among the polyol ester, the phospholipid and the ergothioneine; the ergothioneine is stably coated, so that the obtained end product can be used for effectively resisting destruction to oxidation resistance of the ergothioneine caused by an acidic environment of skin, and the skin retention level in 24 hours can reach 389micrograms/cm<2>; and the preparation process is simple and easy in operation, so that the ergothioneine-lipid complex gel has a broad market application prospect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an ergothioneine lipid complex gel and a preparation method thereof. Background technique [0002] Ergothioneine is a natural small molecular amino acid with a chemical name of 2-mercapto-L-histidine trimethyl inner salt, which has significant antioxidant, anti-ultraviolet (UV) and gamma-ray-induced damage, cell protection, etc. A variety of functions, it is a natural antioxidant. Ergothioneine is abundant in certain mushroom species, red beans, black beans, red meat, liver, kidney, and various grains, but is present in very small amounts in most organisms. It can only be produced by edible fungi, blue-green algae Microorganisms such as bacteria, mycobacteria, and non-yeast fungi synthesize ergothioneine, and humans and other mammals consume ergothioneine only through the diet. Compared with common oxidants (such as glutathione, ascorbic acid, etc.), ergot...
