Abstract
Description
technical field
[0001] The invention relates to the technical field of facial masks and preparation thereof, in particular to a gamma-polyglutamic acid wound-protecting dressing. Background technique
[0002] γ-polyglutamic acid (γ-PGA) is a water-soluble, biodegradable, non-toxic polymer material. It is the main component of the viscous colloid of natto, a natural traditional fermented food. Homogeneous polypeptides polymerized by amide bonds can be produced on a large scale through microbial fermentation and can be naturally degraded. It is a safe and environmentally friendly biopolymer. γ-PGAγ-polyglutamic acid is a special anionic natural polymer, which is composed of amide linkage between α-amino and γ-caboxyl The molecular weight of the homopolyamide (homo-polyamide) γ-PGA ranges from 50,000 to 2 million Daltons. Since γ-PGA is the main component of natto viscous colloid, it has the effect of promoting mineral absorption. , Japan has included γ-PGA in its list of hea...
