Sodium polyglutamate is a product formed by combining with sodium ions after the carboxyl group of the glutamic acid unit side chain of polyglutamic acid is ionized to form an anionic carboxylate (COO-). Polyglutamic acid itself is insoluble in water, and must be ionized to be compatible with water. Sodium polyglutamate has excellent water solubility and is a natural moisturizing ingredient. It is now widely used in cosmetic moisturizing raw materials. This product, sodium gamma-polyglutamate, has the functions of effectively locking water, firming the skin, and reducing eye bags. It can be used in the formulation of skin care products, shampoos, hair creams, shaving creams and lipsticks. This product has good compatibility with other various raw materials, and can be directly added to the water phase during production, which is easy to operate.

Polyglutamic acid is the main component of natto viscous colloid, which has the effect of promoting mineral absorption. At present, Japan has included polyglutamic acid in the list of health care ingredients to promote mineral absorption. The special molecular structure of polyglutamic acid makes it have a strong moisturizing ability. Adding polyglutamic acid to cosmetics or skin care products can effectively increase the moisturizing ability of the skin and promote skin health. Compared with Hyaluronic acid (HA), which is recognized as the most moisturizing agent, the moisturizing effect of polyglutamic acid is 2-3 times higher than its effect. It is a new generation of biotechnology moisturizing ingredients.
Compared with other moisturizing products, polyglutamic acid has many advantages, such as non-toxic to the human body and the environment; biodegradable; good water solubility to obtain an odorless and transparent solution; easy to cross-link to form a hydrogel with excellent performance in the later stage; fully applicable For all skin conditions; only very low concentrations are required for good results, thus lower costs, etc.
In Cosmetic
Polyglutamic acid has the effect of increasing hair toughness and reducing hair damage during hair dyeing. Polyglutamic acid also has a whitening effect, which can significantly inhibit the activity of tyrosinase, thereby inhibiting the production of skin melanin; its water glue is colorless, odorless, transparent and soft colloid; it has a unique three-dimensional structure, so it has super water absorption Moisturizing ability. In addition, polyglutamic acid also has the effect of inhibiting the activity of hyaluronidase, which can alleviate the degradation of hyaluronic acid in the skin connective tissue caused by the activation of hyaluronidase, thereby preventing skin loss caused by loose skin connective tissue. Elasticity and wrinkles. Polyglutamic acid may have triple functions of whitening, moisturizing and anti-wrinkle at the same time, and its application in functional cosmetics will have broad market prospects.
When using it, be aware that ingredients present in cosmetic products containing polyglutamic acid include glutamic acid, sodium glutamate, and ammonium chloride. These three components can cause the viscosity of Carbomer 941 to decrease and destroy its thickening effect. The main functions are sodium ion, chloride ion and glutamate ion. And the greater the ion concentration, the more serious the reduction of carbomer viscosity, but the presence of ions has little effect on the pH of the system.
In Food
Adding 1000 kDa~1200 kDa PGA-Na dough has better farinality effect; adding 300 kDa~400 kDa PGA-Na dough has better pulling effect and frost resistance.
In Biomedical Science
Sodium γ-Polyglutamate is water-soluble and has the characteristics of water absorption, moisturizing, non-toxic, safe, biodegradable, etc. It can increase the tensile strength of the matrix, promote cell proliferation and migration, and can be made into artificial skin, wound dressings, and hemostasis. agents, drug release carriers, bioadhesives, surgical sutures.
