Function:
Polyglutamic acid is a biopolymer with excellent moisturizing ability.
For the skin, polyglutamic acid can provide certain nutrition for skin cells. It is polymerized from glutamic acid, an amino acid that can participate in physiological processes such as protein synthesis during skin metabolism and help maintain the normal function of skin cells.
Application:
Skin care products: It is widely used in various skin care products, such as moisturizers, lotions, essences, facial masks, etc.
Fertilizer synergist: It is added to fertilizers as a fertilizer synergist. It can improve the utilization rate of fertilizers and reduce fertilizer loss.
Food additives – thickeners and humectants: It can be used as a thickener and humectant in food.
