Carboxymethylcellulose (CMC), most commonly used as its sodium salt ( Sodium Carboxymethyl Cellulose or NaCMC), is a water-soluble polymer derived from natural cellulose. Versatile, anionic, hydrophilic colloid known for its exceptional capabilities as a thickener, stabilizer, binder, and rheology modifier for various industry-specific applications. Due to its non-toxicity and high stability, it is universally utilized across the food (E466), pharmaceutical, personal care, and industrial sectors. Also known as Cellulose Gum, Carmellose Sodium, and E466 (Food Additive) by carboxymethylcellulose manufacturers. We are leading & trusted carboxymethylcellulose suppliers in the United States and worldwide, offering high-quality carboxymethylcellulose grades that meet US quality and safety standards, with reliable lead times and global supply capability.

Controls viscosity and prevents syneresis in beverages, sauces, and dressings. Crucial for inhibiting ice crystal growth in frozen desserts (e.g., ice cream) to ensure a smooth texture
Functions as a binder for tablet and capsule formulations, a disintegrant to aid tablet dissolution, and a suspension stabilizer and viscosity modifier for oral syrups, ophthalmic solutions, and topical gels
Used as a fluid loss control additive and viscosity modifier in water-based drilling muds
Water retention functional agent in cement, plasters, and mortars to improve workability and curing
Temporary binder in the manufacture of ceramics, paper sizing, and Lithium-ion battery anodes
Provides viscosity control and stability in shampoos, body washes, and creams. Acts as a film-former and conditioning agent in hair care and as a binder in toothpastes
High humidity conditions (hygroscopic; absorbs >50% moisture)
Aqueous solution pH range 2–10
Below pH 2 (precipitation)
Above pH 10 (rapid viscosity decrease)
Dry-state sterilization at 160°C for 1 hour
Aqueous solution sterilization by heating/autoclaving
Maintain ambient room temperature
NaCMC is a cold-water soluble polymer, forming a clear, colloidal solution. Solubility and final viscosity depend on the Degree of Substitution (DS) and molecular weight.
As E466, its key role is to control viscosity and stabilize emulsions. In frozen desserts, it is crucial for inhibiting the growth of large, gritty ice crystals, resulting in a smoother mouthfeel.
The primary difference is purity and DS (Degree of Substitution). Food/Pharma grades have higher purity (often > 99.5%) and controlled DS to meet regulatory standards, while Industrial grades are tailored for technical applications like oil drilling or construction.
NaCMC is an important binder material for the anode (negative electrode), typically in Lithium-ion batteries. It helps bind the graphite active material to the current collector foil.
