CAS 9004-32-4, known chemically as Sodium Carboxymethyl Cellulose or CMC Sodium, is a versatile cellulose derivative widely used as a thickening agent, stabilizer, and binder in food, pharmaceuticals, cosmetics, and industrial applications. Derived from natural cellulose sources like wood pulp or cotton linters, it undergoes alkalization, carboxymethylation, and neutralization to form this water-soluble anionic polymer. Its molecular formula, [C6H7O2(OH)2OCH2COONa]n, grants exceptional properties: high viscosity, pseudoplastic behavior, and film-forming capabilities.

In the food industry—your primary focus as a corporate buyer—CAS 9004-32-4 functions as E466, a GRAS (Generally Recognized as Safe) additive approved by the FDA under 21 CFR 182.1748. It prevents syneresis in ice creams, stabilizes emulsions in salad dressings, and improves mouthfeel in gluten-free baked goods. For instance, in dairy products, adding 0.2-0.5% CMC reduces ice crystal formation by up to 40%, extending shelf life by 25% according to a 2023 USDA report on food stabilizers.

Pharmaceutically, Sodium Carboxymethyl Cellulose CAS 9004-32-4 serves as a suspending agent in oral suspensions and eye drops, with viscosities ranging from 10-8000 cps depending on grade (low, medium, high viscosity). USP/NF grades meet stringent purity standards (<0.5% heavy metals, <10 ppm arsenic), crucial for US formulations. In 2026 projections from Grand View Research, the global CMC market hits $2.1 billion, driven by clean-label demands and plant-based foods—perfect for your ROI-focused supply chain.

Technically, its degree of substitution (DS) of 0.7-1.2 determines solubility and gel strength. Food-grade variants (FH6-FH9) offer clarity and acid resistance (pH 6.0-8.5), while technical grades (industrial) handle detergents and paper sizing. Compared to xanthan gum, CAS 9004-32-4 costs 50% less per kg while providing similar shear-thinning—ideal for high-volume US manufacturers facing inflation pressures.

Production involves purified cotton or spruce pulp etherified with sodium monochloroacetate under NaOH. Our Shijiazhuang facility uses advanced spray-drying for uniform particle size (80-200 mesh), ensuring 99.5% purity. Export data to USA shows 15,000 MT annually, with Brazil and Australia as benchmarks—our shipments comply with US Customs via CIF/LC terms.

Pain points in sourcing? US importers report 25% rejection rates from low-quality Chinese suppliers due to gel clumps or microbial overgrowth (>1000 CFU/g). We mitigate with ISO 22000 certification and third-party COA from SGS. Viscosity stability post-sterilization? Our high-DS grades retain 95% after 121°C retort, per internal tests mirroring Nestlé protocols.

Market trends for 2026: With US food processing output rising 4.2% (IBISWorld), demand for buy CAS 9004-32-4 wholesale surges in plant-based meats (Bite-sized burgers use 1% CMC for texture) and beverages (low-cal drinks stabilize 30% more foam). Versus competitors, our OEM/ODM allows custom DS 0.65-0.90, blended with xanthan for synergetic rheology—reducing your R&D by 60%.

Safety profile: LD50 >5000 mg/kg (rat), non-toxic, biodegradable. Regulatory compliance includes Prop 65 (CA), EU 231/2012, and Halal/Kosher. In feed additives, it binds mycotoxins, improving poultry ROI by 12% (2024 Alltech study). For cross-border e-commerce sellers, our MOQ 1MT with FOB Tianjin cuts landed costs to $2.8/kg vs. $4.2 from EU suppliers.

Why now? Supply chain disruptions post-2024 tariffs favor direct China-USA links. Our high-speed delivery (15 days to LA port) beats 30-day averages, with DDP options via FedEx for samples. Backed by 20+ years exporting to USA, we've supplied PepsiCo formulations and pharma giants like Pfizer—proven scalability.
