Cosmetics Ingredients Sodium Polyglutamate 92%

What is Sodium Polyglutamate?

Sodium polyglutamate is a product formed when the carboxyl group of the side chain of the glutamate unit of polyglutamic acid ionises to form an anionic carboxylate (COO-), which then combines with a sodium ion. Polyglutamic acid itself is insoluble in water, and must be ionised to be soluble in water. Sodium polyglutamate has excellent water solubility and is a natural moisturising ingredient, and is now widely used as a moisturising raw material for cosmetics.

Benefits:

Long-Lasting Moisturisation

Sodium Polyglutamate is one of the few polymers in nature with a single amino acid structure with a rich branched chain structure that promotes skin absorption. In addition, on the γ-PGA backbone of Sodium Polyglutamate, on average, every 2 to 3 glutamic acid residues, intramolecular hydrogen bonding occurs, reflecting superb hydration ability. Polyglutamic acid has excellent biocompatibility and film-forming properties, which not only effectively isolates and maintains a healthy pH environment in the skin, but also promotes water storage of natural moisturising components within the skin.

Sodium polyglutamate can inhibit the enzyme hyaluronidase and greatly improve the stability of hyaluronic acid. In particular, low molecular weight γ-PGA inhibits hyaluronidase more effectively in the skin. With the increase of γ-PGA, the hyaluronic acid content in the skin increases significantly. Monosodium polyglutamate is the only ingredient known to induce a self-increase in the natural moisturizing factor NMF, which increases by about 130% in the skin, but not in hyaluronic acid or collagen. By promoting the growth of fibroblasts in keratinocytes and increasing the content of NMF, the skin is hydrated from the inside out.

Whitening

Sodium polyglutamate can effectively inhibit the activity of complexing enzymes, reduce melanin production, whiten the skin, and even out skin tone. It has been reported that a complex of monosodium polyglutamate γ-PGA and Vitamin C, in which the carboxyl group of γ-PGA is connected to the hydroxyl group of Vitamin C through ester bonding, improves the stability of Vitamin C, which plays an important role in the skin. In addition, this complex has an inhibitory effect on collagenase.

Improves Skin Elasticity                                                                      

Sodium polyglutamate stimulates the activation of cells, proliferation of NMF in the skin, and functional long-lasting moisturization. According to the results of a study conducted by a Japanese research institute, the amount of natural moisturizing factors in the skin increased significantly after twenty-eight days of using monosodium polyglutamate compared to using hyaluronic acid or sodium PCA salt.

Applications:

In Cosmetics:

Sodium polyglutamate has the effect of increasing hair toughness and reducing hair damage during the dyeing process. Sodium polyglutamate also has a whitening effect, which can significantly inhibit tyrosinase activity, thereby inhibiting the generation of melanin in the skin; Its water-based adhesive is a colorless, odorless, transparent and soft colloid; It has a unique three-dimensional spatial structure, thus possessing strong water absorption and moisturizing ability.

In addition, sodium polyglutamate also has the effect of inhibiting hyaluronidase activity, which can alleviate the degradation of hyaluronic acid in skin connective tissue caused by the activation of hyaluronidase, thereby preventing skin loss of elasticity and wrinkles caused by loose skin connective tissue. Sodium polyglutamate may have a triple effect of whitening, moisturizing, and wrinkle prevention, and it has been widely used in functional cosmetics.

In the Food Field:

The addition of 1000 kDa~1200 kDa sodium polyglutamate dough has a better powder quality effect; The addition of 300 kDa to 400 kDa sodium polyglutamate dough has a good lifting effect and frost resistance. Therefore, high molecular weight polyglutamic acid is also used in food.

Biomedical：

Sodium polyglutamate is water-soluble and has the properties of water absorption, moisture retention, non-toxicity, safety and biodegradability. It can increase the strength of matrix tension, promote cell proliferation and migration, and can be made into artificial skin, trauma dressings, haemostatic agents, drug release carriers, biological adhesives, surgical sutures, and thus used in biomedical fields.
