Moisturing cosmetic Material Polyglutamic Acid Powder
Basic Information
Polyglutamic Acid Powder also called Gamma PGA,its chemical name is L-Glu-(L-Glu)n-L-Glu,it is a water-soluble polyamino acid produced by microbial fermentation in nature.
Polyglutamic acid has good water solubility, strong adsorption, and can be degraded. The degradation product is pollution-free glutamic acid, which is an excellent environmentally friendly polymer material.
Polyglutamic Acid is divided into cosmetic grade, food grade, water treatment grade, and Agricultural grade.Our company mainly produce food and cosmetic grade, which is a white powder with a molecular weight of 20000 to 2 million Dalton.

Polyglutamic Acid Advantage
High Security
Polyglutamic Acid Powder is produced through fermentation, which is natural, highly soluble, and extremely safe
Strong moisturizing and hydrating properties.
The moisturizing ability is at least 2-4 times that of hyaluronic acid, and even up to 500 times higher
Low viscosity
Polyglutamic Acid has low viscosity and is more easily absorbed by the skin

Polyglutamic Acid powder Features & Benefits
Ultra‑powerful humectant: holds 4–10× more moisture than HA, with up to 4,000–5,000× capacity compared to water weight
Dermal barrier enhancement: seals skin moisture and boosts natural moisturizing factor (NMF) production-lactic acid, pyrrolidone, urocanic aci
Anti‑wrinkle & elasticity: deeply hydrates to plump fine lines; superior to HA in smoothing effect
Hyaluronidase inhibition: slows degradation of natural HA in skin
Biodegradable & non‑toxic: derived from Bacillus fermentation, eco‑friendly
Variable molecular weight: tailor for surface hydration (high MW) or deeper penetration & antioxidant support (low MW) .
Application
Polyglutamic Acid Powder can be widely use in food,cosmetic,agricultural etc field:
Food Field
Increase calcium and mineral absorption, antioxidant properties, extend food shelf life, and enhance food taste
Cosmetics Field
Polyglutamic Acid has moisturizing, whitening, and soothing effects on the skin
Agriculture Field
It can be used as a nutrient for increasing plant yield, with good water retention, promoting plant production, and maintaining soil mineral balance

FAQ
Q1: Recommended usage concentration in cosmetics?
Suggested 0.3–3% in aqueous formulations. High MW for surface hydration; blend with low MW for deeper effect .
Q2: Can it combine with HA or vitamin C?
Yes-PGA enhances HA retention and works synergistically with vit C & niacinamide
Q3: Is it safe for sensitive skin?
Non‑irritating; patch test recommended. Low allergy reports
Q4: What MW suits serums vs creams?
Low MW (5k Da) penetrates better; high MW (700–1000 k Da) excels at surface film
Q5: Storage and shelf life?
Keep sealed, < 25 °C, away from light; 24 months.
