Aogubio Supply A natural high-molecular weight amino acid polymer CAS 25513-46-6 Polyglutamate Acid for skin

Basic Information:

Polyglutamate (γ-PGA), also known as natto gum, polyglutamate, is a water-soluble peptide extracted from fermented soybeans.γ-PGA is a widely used raw material, mainly used in cosmetics, pharmaceutical, and industrial fields.Because it is a water-soluble, biodegradable, toxicity-free, using a microbial fermentation system of biological polymers.The polyglutamate developed by our company has the functions of water conservation and fertilizer preservation, disease resistance, stress resistance, heavy stubble prevention, quality improvement and production increase. It can quickly integrate, activate a large number of medium and trace elements in the soil, improve the absorption rate of mineral elements, and achieve the effect of saving fertilizer and increasing efficiency. Polyglutamate is rich in stimulating microbial metabolites and water-promoting factors. The product is organic and inorganic nutrient complex, which can maintain a balanced supply of nutrients.

How Does Polyglutamic Acid Benefit Your Skin?

Polyglutamic acid is an outstanding performer when it comes to hydration. This substance can hold 5000 times its weight in water and is a more powerful humectant than hyaluronic acid. It is capable of attracting more moisture than hyaluronic acid. The more hydrated our skin, the more elastic it is. This makes PGA an excellent anti-aging ingredient as it keeps our skin plump and smooth. Another interesting skin benefit that is turning up in research is polyglutamic acid’s ability to inhibit our body from breaking down its natural hyaluronic acid. PGA also provides wound-healing benefits due to its ability to retain moisture and has been used for wound healing and adhesives for many years.


(I) Application of polyglutamic acid in fertilizer

Polyglutamate ecological fertilizer additives made by microbial fermentation can reach the molecular weight of 3 million, the added efficiency fertilizer can be increased from 30-35% to 40-50%, fertilizer utilization rate by 8%, crops by 10-25%, and rhizome crops by 30-60%.Statistics show that there are 3 million tons of various polyglutamate efficiency fertilizers every year, equivalent to the use area of 60 million mu.Polyglutamate is formed by glutamate monomer by amide bond polymerization of a homo amino acid, it is a biological polymer material, by monosodium glutamate and glucose and other raw materials prepared by fermentation of the third generation of amino acid, adsorption, etc, add compound fertilizer, compound fertilizer, organic fertilizer, urea, water-soluble fertilizer to reduce fertilizer nutrient loss, improve the utilization rate of fertilizer, regulating plant growth, is a new generation of fertilizer synergist.It has significant application effect in rice, wheat, corn, peanut, sweet potato, yam, vegetables, fruit trees and other plants, which can significantly improve the crop yield by 10% -25%, and increase the yield of root crops by more than 30%.

The mechanism of polyglutamate in promoting plant growth has three stages:

Stage 1: Polyglutamate has strong water retention, which can reduce water loss and drought resistance; it is a trace element and can improve the microbial structure of the soil.

Stage 2: Polyglutamate is used as a biological stimulus and signaling material.It can increase the efficiency of plant photosynthesis; it can increase plant resistance.The simplest thing to be said is that the worse the environment, the better the effect, at this time its stress resistance will be reflected incisively and vividly.

Stage 3: Into the amino acid is directly absorbed.

(II) Application of γ-PGA in the cosmetic field

γ-PGA moisturizing water lock works 500 times better than hyaluronic acid.In addition to the better than quality performance, there is a more direct and important reason that the use of γ-PGA is safer than hyaluronic acid. γ-PGA can be used as a fairly safe “non-animal” skin care, cosmetics, raw material.Special molecular structure, make it has a strong moisturizing ability, can effectively increase the moisturizing ability of the skin, promote skin health, its super moisturizing ability is better than hyaluronic acid and collagen, for a new generation of biotechnology moisturizing ingredients.-PGA can not only form a water mesh membrane on the surface skin, reduce the loss of water molecules, but also penetrate deep into the inner layer, improve the content of natural moisturizing factors, so as to achieve the purpose of efficient water conservation, and make the water content of the skin reach a full state.

Using a facial mask supplemented with polyglutamate was found:

10 seconds, the skin feels smooth, and polyglutamate instantly dives into the skin and locks the water.

1-2 days, facial skin is obviously moist and smooth, touch is tender.

7-9 days, skin is full of elasticity, tight skin, white skin begins to change.

15-16 days, pouch shrink, loose skin becomes tight, fine corners of the eyes become light, color spots imperceptibly become light.

At 1 month, skin is tender and full of elasticity
For other moisturizing ingredients, we also can provide Hyaluronic Acid, Allantoin, Ceramide, Collagen, D Panthenol, Sodium Pyrrolidone Carboxylate…

Comparing Polyglutamic Acid and Hyaluronic Acid

The question many skincare lovers are asking is: Is polyglutamic acid better than hyaluronic acid? The research is ongoing but it’s certainly an ingredient that is gaining popularity and appearing in more skincare products. Hyaluronic acid is well known for its ability to attract and retain water. This is what makes it a hero hydrator. But polyglutamic acid holds five times more moisture than hyaluronic acid. This may seem like a big difference, but what does it really boil down to?

Hyaluronic acid performs differently as a hydrator because there are different sized hyaluronic acid molecules. The smaller the molecule, the better it can be absorbed by our skin. PGA is a larger molecule that can’t be absorbed by our skin so it remains on the surface. This isn’t necessarily a negative quality, though. PGA forms a film on the surface of our skin and keeps it looking glassy and plump. In my opinion, the different properties don’t necessarily make one ingredient better than the other in skincare products. The reality is the two combined could be a powerful skincare duo.

XI’AN AOGU BIOTECH CO.,LTD is devoted into the research and innovation in natural nutritional supplements ingredients. Our own factory and lab with the strict quality control system to ensure quality stability and real price of Polyglutamate Acid.
