❌ Problem: "Our current supplier’s cellulose clumps in water-based systems."

Formulators in paint, coatings, and adhesives report that traditional hydroxyethyl cellulose (HEC) and HPMC often fail to disperse evenly, leading to defects, rework, and customer complaints.

✅ Our Solution: Hydrolyzed cellulose with pre-treated surface chemistry for instant wetting.

Our proprietary hydrolysis process modifies cellulose fibers at a molecular level, ensuring rapid dissolution without agglomeration. Tested by BASF and AkzoNobel in high-shear mixing environments.

❌ Problem: "We’re paying premium prices for inconsistent viscosity."

Construction chemical manufacturers in Southeast Asia and the Middle East struggle with batch-to-batch viscosity variations, forcing them to overdose additives — driving up costs and reducing shelf life.

✅ Our Solution: Precision hydrolysis for controlled molecular weight distribution.

Our patent-pending hydrolysis technique ensures ±2% viscosity consistency across batches, eliminating the need for costly viscosity adjusters.

❌ Problem: "Certifications are a nightmare — FDA, Halal, Kosher, you name it."

Pharma and food-grade buyers face lengthy, expensive certification processes, often requiring multiple retests and supplier audits.

✅ Our Solution: Pre-certified options for food, pharma, and cosmetics.

We offer FDA GRAS, Halal, Kosher, and USP/NF grades — ready for immediate integration. Our EU and US labs handle all testing, saving you 4–6 weeks.

140,000 m² facility with 90,000 m² of production space, including ISO 9001:2015 certified labs.

All processes adhere to ISO 9001, REACH, and FDA 21 CFR Part 170 standards. Annual third-party audits ensure compliance.

✅ Vertical Integration:

• Own pulp sourcing (sustainable wood sources in China).
• In-house hydrolysis reactors with real-time analytics.
• On-site packaging for 25kg bags, 500kg FIBCs, and bulk.

🚀 Speed to Market:

• Prototyping in 7–10 days (vs. industry average of 3–4 weeks).
• Production lead time: 14 days for standard grades; 21 days for custom.
• Just-in-Time (JIT) inventory reduces storage costs by 30%.

📝 Requirements Gathering

Submit your RFQ via our contact form or email. We’ll schedule a technical consultation within 24 hours.

⚙️ Prototype Development

Our lab produces a 7–10 day prototype based on your specs. We provide free samples (250g–1kg) and data sheets.

🔍 Pilot Batch Testing

If the prototype meets your needs, we move to a pilot batch (50–500kg). Includes third-party lab validation if required.

🏭 Full Production

Once approved, we lock in your custom hydrolysis profile and initiate bulk production (lead time: 14–21 days).

📦 Quality Inspection & Delivery

Every batch undergoes HPLC, viscosity, and microbial testing. We provide certificate of analysis (COA) and arrange logistics.

🔹 What’s the difference between hydrolyzed cellulose and regular cellulose?

Hydrolyzed cellulose undergoes a controlled hydrolysis process that modifies its molecular structure, making it:

• Faster dissolving (cold water solubility).
• More stable (reduced syneresis).
• Easier to disperse (no clumping).

Regular cellulose requires heat or high shear to dissolve, which is impractical for many industrial applications.

🔹 Can you match a competitor’s sample?

Absolutely. Send us a 250g sample of your current supplier’s product, and our lab will analyze viscosity, pH, and particle size. We’ll then tailor our hydrolysis to match your needs — often at 10–20% lower cost.

🔹 What’s your minimum order quantity (MOQ)?

Our MOQ is 50kg for standard grades. For custom hydrolysis profiles, the MOQ is 200kg. We also offer trial kits (1–5kg) for R&D purposes.

🔹 How do you handle international shipping and customs?

We partner with DHL, FedEx, and Kuehne+Nagel for door-to-door delivery. All documentation (commercial invoice, packing list, COA) is prepared in advance to expedite customs clearance. Lead times:

• EU: 7–10 days.
• USA: 10–14 days.
• Southeast Asia: 5–7 days.

🔹 Do you offer long-term contracts or volume discounts?

Yes. For annual contracts of 5+ tons, we offer 5–10% volume discounts. We also provide price locks for 6–12 months to hedge against raw material volatility.

🔹 What’s your return policy?

If the product doesn’t meet your specifications, we offer a full refund or replacement within 30 days of delivery. No hidden fees.

🔹 How do I get started?
