The role of polyglutamic acid

Polyglutamic acid, also known as natto gum or polyglutamic acid, is a water-soluble substance. It is a biological polymer obtained by microbial fermentation. It has a good effect on body conditioning, can maintain skin elasticity, has a good beauty and skin care effect, and has a good moisturizing effect. It can play a good role in improving the body's immunity and promoting skin health.

The role of polyglutamic acid

γ-PGA polyglutamic acid is a sticky substance that was first discovered in "natto" - fermented beans. γ-PGA polyglutamic acid is a special anionic natural polymer. It is a homo-polyamide composed of α-amino and γ-carboxyl groups via amide linkage. The molecular weight of γ-PGA ranges from 50,000 to 2 million Daltons. Its moisturizing and water-locking effect is 500 times that of hyaluronic acid.

The main functions of γ-PGA polyglutamic acid in cosmetics

1. Functional long-lasting moisturizing to help skin resist dry environment.

2. Increase skin elasticity and enhance skin's smoothness.

3. Inhibit the production of skin melanin.

4. Maintain healthy pH value of skin.

5. Form a sustained-release delivery system to enable the skin to absorb various skin nutrients in skin care products more efficiently.

6. γ-PGA polyglutamic acid and γ-PGA Hydrogel increase the color fastness of hair after dyeing.

7. γ-PGA polyglutamic acid and γ-PGA Hydrogel increase hair strength and reduce hair split ends and breakage.

8. γ-PGA polyglutamic acid and γ-PGA Hydrogel improve the combing properties of hair.

Origin of γ-polyglutamic acid

Natto is a traditional fermented soybean food often consumed by Japanese people. After fermentation, natto contains more vitamins (B2, B6, B12, E, K2) and easier-to-digest protein than soybeans themselves. In addition, natto also contains a variety of digestive enzymes and special polysaccharides (Levan) that are helpful to health, thrombus-decomposing enzyme (Nattokinase) and γ-polyglutamic acid (γ-PGA), etc. It has an excellent effect on promoting health. In recent years, it has become quite popular to eat natto to improve health.

γ-PGA is the main component of natto's viscous colloid and has the function of promoting mineral absorption. Currently, Japan has included γ-PGA in the list of health ingredients that promote mineral absorption. The special molecular structure of γ-PGA gives it extremely strong moisturizing ability. Adding γ-PGA to cosmetics or skin care products can effectively increase the skin's moisturizing ability and promote skin health. Compared with hyaluronic acid (HA), which is recognized as the most moisturizing agent, the moisturizing effect of γ-PGA is 2-3 times stronger, making it a new generation of biotechnology moisturizing ingredient.
