The basic structure of Sodium polyglutamate (PGA) consists of D- and L-glutamic acid monomers which are connected by amid linkages between α-amino and γ-carboxyl groups. Large number of carboxyl along the molecule chain of PGA can form hydrogen bonding in a molecule or between different molecules.
1. Moisturizing skin for longer hours
PGA has very strong hydration ability because of large number of hydrophilic groups along the molecule chain of PGA.
The transepidermal water loss (TEWL) experiment found that the moisturizing effect of PGA-HMW is better than that of hyaluronic acid and collagen
2. Unique smooth skin feeling
PGA-HMW can bring very smooth skin feeling, water-skiing touch feel, and can effectively reduce the viscosity caused by hyaluronic acid.
Skin moisturizing and healthy whitening
1. Healthy whitening
Tyrosinase is a key enzyme for the production of melanin in human skin. Studies found that PGA-LMW can mildly inhibit the function of tyrosinase and delay the formation of pigmentation. Brightening skin more gentle, PGA-LMW can achieve the efficacy of skin healthy brightening.
2.Increasing and Maintanining HA of Skin
Hyaluronic acid (HA) is a natural component in human skin, but hyaluronidase (HAase) also exists in the skin. PGA-LMW can inhibit the activity of HAase, thus improve the stability and content of HA in skin.
