Sodium Polyglutamate CAS 28829-38-1
Sodium polyglutamate is found in the traditional food natto. It is a sticky amino acid anionic polymer and is usually also called γ -polyglutamic acid. Sodium polyglutamate is a homogeneous polypeptide biopolymer with glutamic acid as the structural unit, forming amide bonds through α -amino and γ -carboxyl groups. Due to the fact that each structural unit of glutamic acid contains multiple hydrophilic groups, a large number of hydrogen bonds can be formed within the polymer chain or between molecules, making polyglutamic acid have excellent water absorption and moisture retention properties, and thus become an outstanding natural moisture retention component. And sodium polyglutamat is widely used in personal care products.

Sodium polyglutamate with a higher molecular weight provides a smooth skin feel. It can promote the accumulation of natural moisturizing factors, enhance the skin's water retention capacity, and work synergistically with HA to improve skin elasticity and softness. Therefore, polyglutamate sodium can be widely applied in various product and cosmetic formulas, such as creams, lotions, essences, masks, cleansers, hair care products, and body care products.
1.Long-lasting moisturizing and smooth skin feel
The side chains of high-molecular-weight polysodium glutamate contain a large number of hydrophilic groups and have a strong water-locking capacity.
High-molecular-weight sodium polyglutamate has a very smooth skin feel, a silky and moist touch, and can effectively reduce the stickiness of hyaluronic acid.
2. Moisturizing and whitening, synergistic effect with HA
Low-molecular-weight polyglutamate sodium can inhibit the activity of HA enzymes in the skin, improve the stability of HA in the skin, and increase the content of HA.
Low-molecular-weight sodium polyglutamate also has the effect of inhibiting tyrosinase activity, achieving a mild whitening effect.
3. Increase the content of natural moisturizing factors in the skin
Ultra-low molecular weight polyglutamate sodium has a relatively low molecular weight, less than 10kDa, and a higher skin penetration rate, making the skin plump and hydrated.
Ultra-low molecular weight polyglutamate sodium can increase the NMF content of the stratum corneum, thereby enhancing the skin's water capacity.
