Description
Sodium Polyglutamate is an isomorphism type of polypeptide biopolymers with glutamic acid as a structural unit and connected by amide bond formed through α-amino and γ-carboxyl group. Since each of the structural unit of glutamic acid contains a plurality of hydrophilic groups, a large amount of hydrogen bonds can be formed between the molecular chain and water, which makes Sodium Polyglutamate have a good water absorption and moisture retention. Sodium Polyglutamate with higher molecular weight makes the skin feel smooth. It can promote the accumulation of natural moisturizing ingredients to enhance the water holding capacity of the skin, and works in concert with HA to improve skin elasticity and softness. It can be widely used in various forms of products and formulation such as cream, lotion, essence, facial mask, cleanser, hair products and body care products.
