Sodium Polyglutamate
A moisturizing biopolymer offered in multiple molecular-weight grades for long-lasting hydration and HA synergy.
Sodium polyglutamate (PGA) is a water-soluble high molecule polymer produced by microbial fermentation. There are a large quantity of hydrogen bonds between and within the molecules of PGA contributing to the excellent moisturizing capability of the material. Using PGA and HA together can greatly increase the action time of HA and bring about smoother skin feeling by decreasing the sticky feeling of HA.
