What is polyglutamic acid?


Polyglutamic acid (PGlu) is a water-soluble, biodegradable and non-toxic polymer.


Polyglutamic acid is the main component of natto viscous colloid, which has the effect of promoting mineral absorption.


Due to the special molecular structure of polyglutamic acid, it has a strong moisturizing ability. Adding polyglutamic acid to cosmetics or skin care products can effectively increase the moisturizing ability of the skin and promote skin health.


The moisturizing ability of polyglutamic acid is 2-3 times that of hyaluronic acid (HA).
