Applications:
1. Microcrystalline Cellulose MCC
High alpha-cellulose + viscosity 408 cm³/g = high yield, stable flow properties for pharma tableting excipients.
2. Carboxymethyl Cellulose CMC / HPMC
Cotton linter base reduces pre-treatment time. Cleaner etherification vs wood pulp. Used in food, pharma, detergents.
3. Cellulose Acetate & Ethers
Low hemicellulose content improves filtration and optical clarity for acetate plastics and specialty films.
4. Specialty Paper & Filtration
Long fiber length from cotton linters gives strength + purity for battery separators, cigarette paper, lab filters.

Why Cotton Linter Cellulose vs. Wood Pulp
1. Higher alpha-cellulose: 98.6% vs 92-95% for wood. Less chemical waste.
2. Cleaner reaction: Lower lignin/hemicellulose = fewer purification steps for CMC/HPMC.
3. Consistency: Cotton linter gives tighter batch-to-batch viscosity than wood pulp.
4. EU Stock: EU warehouse cuts lead time and carbon footprint for EU buyers.
Request COA & Samples
Pharma and food buyers need to test before contract. We provide:
1. Full COA with batch traceability
2. 1-2 bale samples for lab/R&D trials
FAQ:
What is cotton linter cellulose?
Cotton linter cellulose is purified cellulose from cotton seed fibers. It has 98%+ alpha-cellulose and is preferred for pharma-grade MCC and CMC vs wood-based cellulose.
Can you supply for food grade CMC?
Yes. Our 98.6% alpha-cellulose cotton linter meets FCC/EU food grade requirements. COA includes heavy metals + microbiology on request.
Minimum order quantity?
MOQ is 1 truckload ∼22 MT from EU warehouse. Long-term contracts for 2000+ MT/month available.
