Whether you're formulating a luxury serum, a hydrating mask, or a professional hair-care line, UCHEM offers a molecular-weight and functional match.

Eye-Drop Grade — Purity Beyond Pharmacopoeia Standards

UCHEM's eye-drop grade HA exceeds European Pharmacopoeia benchmarks in the parameters that matter most:

The 700-fold lower endotoxin and 6-fold lower protein levels speak to a fermentation-and-purification process refined over decades — critical for ophthalmic and wound-care applications where patient safety is paramount.

Injection Grade — Meeting the Most Demanding Standard

For intra-articular, intraocular, and dermal-filler applications, UCHEM provides injection-grade HA powder with:

• Purity ≥ 99%
• Endotoxin ≤ 0.05 IU/mg (actual: 0.0005–0.0006 IU/mg)
• Residual ethanol ≤ 5,000 ppm
• Available in MW range 800–2,000 kDa
• Customizable viscosity and format (solution / lyophilized powder)
• Sterile vial packaging

This grade meets the stringent requirements of ISO 13485 medical-device quality systems and is backed by UCHEM's FDA DMF Type II (No. 036068) filing — a critical prerequisite for any injection-grade ingredient entering the U.S. market.

Cross-Linked HA — The Filler Industry's Backbone

UCHEM's BDDE cross-linked HA products offer:

• Cross-linking degree: 6–8%, customizable
• Available as both powder and pre-formed gel
• Homogeneous gel (single cross-link) and dual-phase (particle + free HA) architectures
• Tiered particle sizes for shallow-to-deep tissue layers (100 μm → 1,000 μm)
• In-body residence time: 6–18 months
• Non-animal fermentation origin — no BDDE-residue concerns at controlled cross-link levels

For dermal-filler manufacturers seeking a reliable, certifiable raw-material partner, this is a production-ready solution.

Food Grade — Approved for Global Nutraceutical Markets

UCHEM's food-grade HA (content ≥ 87%, MW up to 4 MDa) complies with China's 2021 new-food-ingredient approval for Sodium Hyaluronate, with established usage limits across dairy, beverages, confectionery, and frozen desserts. Combined with ISO 22000 / HACCP / FSSC 22000 / Halal certifications, this grade is positioned for international nutraceutical and functional-food launches — joint-health capsules, beauty drinks, oral HA tablets, and more.

Certification Matrix: Compliance Without Compromise

This certification breadth — spanning pharma, food, cosmetic, and regulatory registrations — means one supplier, one audit trail, multiple product grades, dramatically simplifying your compliance workload.

Customization: Not Just a Promise, a Process

UCHEM doesn't just sell catalog products. Their engineering team works with clients on:

• Molecular-weight targeting — specific MW windows for proprietary formulations
• Derivatization tuning — acetylation degree, cationization level, cross-link density
• Packaging formats — from 100 g lab samples to 25 kg industrial drums, sterile vials for injection grades
• Multi-HA blend design — 4D/9D cocktails tailored to your product's hydration strategy

For brands developing next-generation formulations, this level of raw-material partnership is invaluable.
