Abstract

The present invention relates to the technical fields of facial masks and a preparation method thereof, and particularly to a gamma-polyglutamic acid wound-protecting dressing. The gamma-polyglutamicacid wound-protecting dressing contains 0.05-0.1 wt% of gamma-polyglutamic acid. The gamma-polyglutamic acid is added into the facial mask dressing, can effectively increase moisturizing ability of the skin and promotes skin health; and in addition, a certain amount of the gamma-polyglutamic acid is added into the facial masks, can kill bacteria on the surface of the skin, promotes healing of skinwounds and plays a wet heating function during a facial mask applying process, and further promotes skin health.

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...
