Polyglutamic Acid Powder Skincare 99%

What is Polyglutamic Acid Powder?

Polyglutamic acid (γ-PGA) is a secondary metabolite produced during the life activities of Bacillus genera such as Bacillus subtilis and Bacillus licheniformis, and was first found in the pods of Bacillus anthracis. It is a naturally occurring anionic polypeptide consisting of D-glutamic acid or L-glutamic acid. It is polymerised by γ-amide bonding between α-amino and γ-carboxylic acid groups, and mostly consists of 500 to 5 000 glutamic acid monomers. Polymers have high stability and high compression resistance. Polyamino acids have been rapidly developed in recent years as a widely studied biodegradable nano drug carrier due to their high structural and functional similarity to natural proteins.

The free carboxyl group in the repeating unit of polyglutamic acid facilitates drug attachment, and this advantage allows polyglutamic acid to be a carrier for polymer-drug conjugates. In addition, γ-PGA can exist as a water-soluble salt in the presence of various cations or as a water-insoluble free acid, so the stability of polyglutamic acid is more excellent. Polyglutamic acid can be used as a carrier for cosmetic active ingredients, and it also has many good effects, such as moisturizing, antioxidants, and thickening.

Benefits:

Moisturising

Due to the special three-dimensional lattice structure of polyglutamic acid, the molecular structure is full of helices and folded structures. This structure encapsulates more nutrients, making it extremely absorbent and moisturising. Polyglutamic acid contains three functional groups with hydration capacity, which in the skin induces the skin's natural production of moisturising factor (nmf). It can absorb more than 5,000 times its mass of water, which significantly improves the skin's moisturising efficacy, reduces water loss, promotes skin elasticity, and keeps the skin moisturised for a longer period. Compared with hyaluronic acid, polyglutamic acid powder has a more complex moisturising mechanism, and its moisturising and water-locking effect is increased by 1000 times. Under experimental conditions, polyglutamic acid can absorb 4,000 times its water, the best up to 5,000 times.

Antioxidant

Polyglutamic acid contains a large number of anionic groups and has a strong ability to chelate cationic metals. It can chelate with metal ions and thus block the interaction of metals with lipids or peroxides. It reduces the production of free radicals and has an antioxidant effect.

Thickening

It has been shown that hybrid systems of polyglutamic acid and hydroxyethyl cellulose (HEC) have a synergistic effect on rheology. There was a significant synergistic viscosity increasing effect when HEC and polyglutamic acid were mixed at different mass ratios. At the same time, the synergistic effect increased and then decreased with the increase of the mass ratio of HEC and γ-PGA, and the overall strain resistance of the solution was enhanced after HEC blended with γ-polyglutamic acid, i.e., the structure of the system after blending was enhanced to a certain extent.

Whitening

Studies have shown that polyglutamic acid has a good inhibitory and regulatory effect on tyrosinase activity. Among them, the low molecular weight polyglutamic acid powder whitening effect is obvious, defense against ultraviolet rays, blocking melanin production, from the root to start whitening and brightening.

Slow Release

Polyglutamic acid powder can inhibit the growth of microorganisms, play an antibacterial effect, slow biodegradability, the skin surface is not easy to breed microorganisms, can be used to build the embedded slow-release system, promote skin absorption, film on the skin surface, isolation of environmental stimuli, reduce skin inflammation.

Applications:

In Agriculture Field:

Polyglutamic acid powder as a fertilizer synergist can promote crop nutrient absorption, increase yield, improve quality, improve crop resistance, and effectively reduce the amount of fertilizer applied. Polyglutamic acid synergists can increase the above and below ground plant growth of rice, the number of solid grains in the ears, and the number of effective ears. Using polyglutamic acid to apply to maize can significantly increase the chlorophyll content, root vigor, and biomass of maize seedlings, and increase the 100-kernel weight and the number of solid grains on the ear, thus increasing the yield.

In Cosmetics:

Polyglutamic acid has moisturising, antioxidant, and thickening properties. Low molecular weight polyglutamic acid can be absorbed by the skin and achieve a deep moisturising effect. High molecular weight polyglutamic acid can form a film on the surface of the skin with a water-locking and moisturising effect. As a cosmetic raw material, polyglutamic acid powder has been added to face masks, morning and evening creams, shampoos, skin care ointments and so on.
