Polyglutamic Acid Powder

Premium Polyglutamic Acid Powder 99% Purity – Ultra-Hydrating Natural Fermentation Solution for Advanced Cosmetic Formulations

Pharmaceutical grade Polyglutamic Acid Powder (99% purity) from controlled natural fermentation from Xi'an Yanxi Biotech. This super-fine white powder soaks up to 1000 times its weight in water and it offers 72 hours of continuous skin moisturization against hyaluronic acid. This product is fully vegan certified, with heavy metals content <10 ppm and ash content <5%. It is ISO 22000, HACCP, Kosher and Halal certified for global cosmetic and personal care applications. We guarantee a reliable supply and delivery of in-stock orders within 1-3 days from our integrated production facilities.

What Makes Our Polyglutamic Acid Powder Unique?

It is a biopolymer produced by fermentation of Bacillus subtilis and is made up of long-chain polypeptides of gamma-linked glutamic acid units. The molecular framework forms a permeable moisture coating on skin surfaces that is not occlusively heavy, unlike conventional humectants.

With 99% test purity there is consistent batch to batch performance in formulation. Each particle is passed thru an 80-mesh screen to give consistent dispersion in water based systems. The loss on drying is maintained at 5% to prevent degradation from moisture during storage.

Total plate count less than 1000 cfu/g and yeast and mould less than 100 cfu/g. These microbiological limitations are consistent with the high cosmetic safety criteria for leave-on products and facial masks.

Technical Specifications & Quality Parameters

Superior Hydration Technology for Cosmetic Applications

This naturally fermented polymer binds moisture thru numerous carboxyl groups along its peptide backbone. The water retention ratio is up to 1000: 1, forming a non-oily protective film to keep the skin moisturised for 72 hours after application.

Clinical tests indicate that it holds moisture 5X better than sodium hyaluronate at equal amounts. Its non-ionic nature inhibits electrostatic interaction with cationic surfactants usually seen in emulsions and serums.

Formulators add 0.5-2% concentrations for skin serums, 1-3% for sleeping masks and 0.3-1% for hair conditioners. The powder dissolves easily in deionised water at 40-50°C within 20 min with gentle stirring to give clear viscous solutions.

Certified Quality Standards for Global Compliance

Xi'an Yanxi Biotech conforms to ISO 22000 food safety management and HACCP hazard analysis. Each production batch is tested for heavy metals, microbes and residual solvents by a third party SGS.

Orthodox Union Kosher Certification and Islamic Food and Nutrition Council Halal Certification are assurances of adherence to religious dietary regulations. These certifications will make our products more marketable to Middle Eastern and Jewish consumers.

FDA registration number allows for simple customs clearance of North American imports. Each shipment is accompanied by COA (Certificate of Analysis) and MSDS (Material Safety Data Sheet) for full traceability documentation.

Versatile Formulation Integration Across Product Categories

Anti-Aging Serums: Works synergistically with peptides and vitamin C derivatives. Its polypeptide structure resembles that of the skin’s natural moisturising elements and promotes hydration of the dermis, allowing the active substances to penetrate.

Sheet Masks & Hydrogels: Disperses uniformly in essence solutions at room temperature. The film-forming characteristic inhibits quick evaporation from the mask substrates and increases contact time for active delivery.

Hair Care Systems: Protects hair cuticles by creating a covering around damaged keratin components. Especially useful in leave-in conditioners for chemically treated hair requiring moisture balance restoration.

Post-Procedure Recovery: Gentle, non-irritating product for sensitive skin, post-laser and post-peel. The biopolymer promotes faster barrier restoration without the inflammation seen with synthetic polymers.

Packaging & Shipping

Standard packaging is 1kg aluminium foil bags with nitrogen flushing, 5kg carton boxes with double polyethylene lining, and 25kg fibre drums with food-grade inner coating. Containers are sealed moisture-proof to guarantee powder flowability throughout transit.

We manage express shipment with DHL, FedEx and UPS for samples and small orders. Bulk cargoes are sent by sea in chilled containers for tropical route destinations. The average transport time for air freight is 7-10 days and 25-35 days for ocean cargo.

Custom labelling and private branding is available on orders above 100kg. Documentation: Commercial invoice, packing list, phytosanitary certificate and non-GMO declaration as required by destination country legislation.

FAQ

Q: What specific quality standards does this powder meet for international markets?

A: Our product complies with EU Cosmetic Regulation 1223/2009, US FDA 21 CFR Part 700, and China NMPA cosmetic ingredient standards. Heavy metal limits follow USP <232> and <233> guidelines with ICP-MS verification.

Q: What is the lead time for bulk orders?

A: In-stock quantities ship within 1-3 business days. Custom production batches require 15-20 days from PO confirmation. We maintain 10-ton safety stock to accommodate urgent requests and seasonal demand spikes.

Q: How should formulators handle pH sensitivity?

A: The polymer maintains structural integrity in pH 5.0-7.0 range. For formulations requiring pH above 7.5, consider adding at the final cooling stage below 40°C to minimize degradation. Buffer systems with citric acid or lactic acid provide optimal stability.

Q: Is this suitable for vegan and cruelty-free certifications?

A: Yes, the fermentation process uses plant-based glucose substrates without animal-derived components. We provide Vegan Society trademark licensing documentation and Leaping Bunny program compliance statements.

Q: What causes batch-to-batch viscosity variations?

A: Molecular weight distribution naturally varies ±10% between fermentation cycles despite controlled conditions. We standardize batches by blending to achieve consistent 1% solution viscosity of 50-200 cP at 25°C.
