Poly-γ-Glutamic Acid γ-PGA 25513-46-6

What is Poly-γ-Glutamic Acid?

Natto is a traditional fermented soybean food that Japanese people often eat. After fermentation, natto contains more vitamins (B2, B6, B12, E, K2) and more digestible protein than soybean itself. In addition, natto also contains a variety of digestive enzymes and special health benefits. Polysaccharides (Levan), thrombolytic enzymes (Nattokinase), and Poly-γ-glutamic acid (γ-PGA), etc., have excellent effects on promoting health. In recent years, the consumption of natto is quite popular to promote health.

γ-PGA is the main component of natto viscous colloid, which can promote mineral absorption. 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 moisturizing ability of the skin and promote skin health. Compared with Hyaluronic acid (HA), which is recognized as the most moisturizing ability, the moisturizing effect of γ-PGA is 2-3 times more than its effect. It is a new generation of bio-tech moisturizing ingredients.

Function of Poly-γ-Glutamic Acid

1.Active component for lasting moisturizing and resistance to dry conditions of human skin.
2.Poly-γ-Glutamic Acid can increase the elasticity of human skin and keeping it tight and smooth.
3.Poly-γ-Glutamic Acid can inhibit the formation of melanin remarkably.
4.Poly-γ-Glutamic Acid can keep pH balance of human skin.
5.Poly-γ-Glutamic Acid can form a slow-release delivery system and therefore improving the absorption capacity of nutrients in cosmetics.

Application of Poly-γ-Glutamic Acid in cosmetic field

With the improvement of the economic level, people's quality of life is also improving, and more women are pursuing skin care. They are no longer limited to these chemicals in the past, but are pursuing more natural and healthier skin care products. Scientists are also working hard to find a better natural cosmetic ingredient -- Poly-γ-Glutamic Acid.

    The wide application of γ-PGA (Poly-γ-Glutamic Acid) in the cosmetics field is not only better than the quality and performance, there is also a more direct and important reason is that the use of γ-PGA is safer than hyaluronic acid, that is, γ-PGA The cost-effectiveness is obviously better, based on the following: It is well known that hyaluronic acid is mainly made from chicken combs extracted from chickens and poultry; while collagen is made from cattle, sheep, and pig tissues. Therefore, these two products are made from Made from animal raw materials, all belong to animal collagen. Because its production process is more complicated and the raw materials are more expensive, the cost is high and the price is high. And γ-PGA is made of gluten acid and glucose as raw materials and fermented by natto bacteria of the recognized safety level (GRAS), so it belongs to plant collagen. Its safety to the human body has been obtained in many countries such as the United States, Japan, Canada, etc. The health supervision department of China confirmed that γ-PGA is indeed a very safe raw material for “non-animal” skin care and cosmetics. Consumers can use it with confidence.

    The effects of Poly-γ-Glutamic Acid in cosmetics:

1. Efficient moisturizing: γ-PGA can not only form a water reticulum on the surface of the skin, reduce the loss of water molecules, but also penetrate into the inner layer to increase the content of natural moisturizing factors to achieve the purpose of efficient water retention, and under smart conditioning, Make the skin's moisture content reach a full state.

2. Long-lasting moisturizing, proliferation of NMF in the skin

3. Increase skin elasticity, good touch

4. Whitening effect of Poly-γ-Glutamic Acid: inhibit melanin, whiten skin

5. Isolation protection

6. Slow-release effect: inhibit the growth of microorganisms, play an antibacterial effect, slow biodegradability, and it is not easy to breed microorganisms on the skin surface

7. Anti-aging

8. Maintain the PH value of skin health

9. With high stability, non-toxic and harmless, non-irritating to the human body

10. Protect and moisturize hair, good combing
