Application
This product has the functions of strong water lock, firming skin, reducing eye bags, etc. It can be used in the formulation of skin care products, shampoos, hair creams, shaving creams and lipsticks.
The polymer polyglutamic acid has a molecular weight of more than 1 million, which can quickly form a film on the skin surface, at the same time effectively increase the content of natural moisturizing factor (N.M.F) in the skin, reduce the activity of hyaluronidase, and have a long-term moisturizing effect. The high molecular polyglutamic acid has a special feeling of smoothness and smoothness without being greasy. It can be used alone or mixed with hyaluronic acid to improve the sticky feel of hyaluronic acid.
 
Package: 25kg/drum, can also be designed according to customer requirements.
Storage: Store in cool place. Keep container tightly closed in a dry and well-ventilated place.
