Functions
1.  Remarkably potent hydrating compound, ten times more hydrating than hyaluronic acid and far more elastic than    collagen. Long-lasting moisturizing that helps the skin resist dryness.
2.  Improvement of skin elasticity and smoothness
3.  Inhibition of melanin
4.  Maintenance of a healthy pH
5.  Slow-release transport system that enables the skin to absorb all nutrients

Application
Used in products for anti-wrinkle, anti-aging, moisturizing, sunscreen, detoxification and other products.

Use Level   0.05-1.00%

γ-PGA hydrogel
γ-PGA can be made into hydrogels, which show an outstanding water absorption up to approximately 5000 times of its weight, is excellent for agricultural and environmental applications.
