Product introduction：Sodium Polyglutamate (PGA) was first found in the high viscosity wiredrawing contained in natto foods.It is a amino acid anion polymer produced by microbial fermentation, it' s water-soluble, biodegrad-able and of high safety.
The basic structure of PGA consists of D- and L-glutamic acid monomers which are connected by amid linkages between a-amino and v-carboxyl groups. Large number of carboxyl along the molecule chain of PGA can form hydro-gen bonding in a molecule or between different mole-cules. Thus it has high water absorb-ability and mois-ture-retaining capability.
PGA has good biocompatibility and can increase the content of skin natural moisturizing factor (N.M.F). It is a good natural hydrating ingredient. At the same time, PGA-LMW can control tyrosinase function, is a mild skin brightening raw material.
According to the molecular weight, PGA can be divided into many different types, such as PGA-HMW (high molecular weight)（about1000KDa），PGA-LMW（low molecular weight）（about 100KDa），and PGA-Oligo（oligo molecular weight）（about 10KDa）.

The transepidermal water loss (TEWL) experiment found that the moisturizing effect of PGA-HMW is better than that of hyaluronic acid and collagen.
PGA-HMW can bring very smooth skin feeling, water-skiing touch feel, and can effectively reduce the viscosity caused by hyaluronic acid. |
Studies found that ,PGA-LMW can mildly inhibit the function of tyrosinase and brightening skin more gentle, PGA-LMW can achieve the efficacy of skin healthy bright- ening.
PGA-LMW can inhibit the activity of HAase, increasing and maintaining HA of skin |
PGA-oligo can improve the content of N.M.F, and then improve 1the skin's water binding force, promote the production of NMF in inner skin
With low molecular weight, less than 10kDa, PGA-oligo can reach the skin base and make the skin full of water. |
Application
Facial mask, moisturizing lotion, moisturizer, eye cream, shower gel, lotion, body lotion, sunscreen, etc.
Add hyaluronic acid to the finished mask at a ratio of 1:1 to obtain an excellent skin feel and the best moisturizing effect.
