The Advanced Film-Forming Hydrator for Silky Texture and NMF Activation
Sodium Polyglutamate, also known as Gamma-Polyglutamic Acid (γ-PGA), is a high-performance cosmetic grade biopolymer produced through microbial fermentation. Renowned for its superior water-locking capabilities—often surpassing traditional Hyaluronic Acid—it creates a breathable, silky film on the skin that significantly boosts Natural Moisturizing Factors (NMF) while providing an ultra-smooth, non-sticky sensory experience.

Shaanxi Huatai Bio-fine Chemical Co. provides premium cosmetic grade Sodium Polyglutamate, characterized by its high purity and exceptional film-forming properties. Our unique advantage lies in the precision fermentation of these active ingredients skincare, which allows us to offer specific molecular weights tailored for deep penetration or surface protection. As the signature choice for “Next-Gen Hydration” and “Silky Finish” lines, our γ-PGA empowers brands to deliver long-lasting moisture that is not only felt but also improves the skin’s biological ability to retain water.
Sodium Polyglutamate is a natural, biodegradable peptide consisting of cross-linked glutamic acid molecules.
It is highly valued for being more effective at water retention than Hyaluronic Acid and for its unique skin-brightening secondary effects.
Our γ-PGA is refined to ensure a zero-odor, zero-color profile for maximum formulation versatility.
Purity: ≥ 95.0% (Powder form).
pH (1% Solution): 5.0 – 7.5.
Heavy Metals: < 10 ppm.
Stability: Excellent stability in aqueous systems; highly compatible with varied electrolyte environments.

Invisible Film-Forming: Creates a micro-porous film on the stratum corneum that locks in moisture while allowing the skin to breathe.
NMF Activation: Stimulates the production of Pyrrolidone Carboxylic Acid (PCA), Lactic Acid, and Urocanic Acid within the skin.
Hyaluronidase Inhibition: Helps maintain the skin’s natural Hyaluronic Acid levels by inhibiting its degradation enzymes.
Superior Water Absorption: Capable of holding up to 5,000 times its weight in water.
Luxury Skin Feel: Provides a “silky” and “velvety” finish without the tackiness often associated with high-molecular-weight HA.
Brightening & Elasticity: Helps improve skin tone and elasticity by optimizing the hydration environment of the dermal matrix.
Recommended Usage: 0.05% – 1.0% (Powder); 1.0% – 5.0% (Liquid solution).
Processing: Highly water-soluble; can be added to the water phase at any temperature below 80°C.
Compatibility: Highly synergistic with Hyaluronic Acid and other polyols.
Our manufacturing facility is ISO 9001/22000 and HALAL certified.
We strictly adhere to COSMOS approved standards, ensuring our biosurfactants and hydrators meet organic cosmetic criteria.
Every batch of our cosmetic grade Sodium Polyglutamate is provided with a full technical dossier, including COA, TDS, and MSDS.
Sodium Polyglutamate + Hyaluronic Acid: The “Ultra-Hydration Duo” for multi-level moisture (Internal HA + External γ-PGA).
Sodium Polyglutamate + Panthenol: To combine intensive hydration with barrier-strengthening repair.
Sodium Polyglutamate + Pro-Xylane: To create high-end “Filling” products that smooth texture while rebuilding volume.
This ingredient is a core component in “Hydrating Primers,” “Silky Essence Toners,” and “Long-Wear Moisture Creams”.
Brands utilizing our high-purity active ingredients skincare have successfully launched “Silky Dew” lines that differentiate themselves from standard HA products.
Scientific studies demonstrate that γ-PGA increases skin elasticity significantly more than HA after 28 days of use.
Internal lab data confirms that formulas containing 0.5% Sodium Polyglutamate maintain skin hydration levels 20% longer than those using 0.5% HA alone.
