Carboxymethyl Cellulose, commonly known as CMC, is a water-soluble polymer derived from cellulose. It is a white to off-white, odorless, and tasteless powder widely recognized for its thickening, suspending, binding, and stabilizing properties. Its unique molecular structure allows it to hydrate rapidly in cold or hot water, forming highly viscous solutions. This characteristic makes it an indispensable additive across numerous industries, enhancing product performance and quality.

NINGBO INNO PHARMCHEM CO.,LTD. is a dedicated supplier of high-quality Carboxymethyl Cellulose, offering various grades tailored to specific industrial needs. Our product adheres to stringent quality standards, ensuring consistency and reliability for our global customers. The chemical formula for CMC is typically represented as (C6H9O4Na)n, with a CAS number of 9004-32-4 and EINECS number 232-674-9. Its appearance is consistently a fine white powder, making it easy to incorporate into diverse formulations.

The performance of CMC in various applications is heavily influenced by its degree of substitution (D.S.) and polymerization degree, which in turn affect its viscosity. We offer CMC with varying viscosity ranges to meet precise application requirements. Typical specifications include a D.S. between 0.65 and 0.9, a pH range of 6.0 to 8.5 in solution, and purity levels generally between 85% and 99%. These parameters are carefully controlled during manufacturing to ensure optimal functionality.

One of the most significant application areas for CMC is the food industry. Food-grade CMC is a popular additive due to its ability to modify viscosity, prevent ice crystal formation in frozen desserts, and stabilize emulsions and suspensions. In dairy products, particularly acidic milk drinks, it is crucial for preventing protein aggregation, condensing, settling, and lamination, ensuring a smooth and uniform texture. When dissolved, it imparts a smooth, pleasant mouthfeel, making beverages more palatable. Its excellent acid resistance provides drinks with remarkable stability over time. It is also extensively used in baked goods, sauces, dressings, and confectionery, including materials for fondant cake making, where it acts as a binder and texturizer.

Beyond food, CMC plays a vital role in the paint and coatings industry. Here, it serves primarily as a thickening agent and stabilizer. As a thickener, it ensures the coating has a consistent, uniform state, achieving the desired viscosity for both preservation and application. This uniform viscosity prevents dripping and ensures smooth application. As a stabilizer, CMC helps prevent the separation and delamination of paint components, which can occur due to temperature fluctuations or prolonged storage. This contributes significantly to the shelf life and performance of paints.

In the formulation of detergents, CMC is included for its anti-redeposition properties. It effectively prevents washed-out dirt and grime particles from settling back onto the fabric surface during the washing cycle. This action is primarily due to the static repulsion between negatively charged soil particles and the negatively charged CMC molecules adsorbed onto the fabric fibers. Even at low concentrations (typically 0.5-2 percent), it yields satisfactory results. Furthermore, adding CMC helps increase the viscosity of liquid detergents, improving their stability and enhancing their overall washing effectiveness.

The toothpaste industry also relies heavily on CMC. It acts as a binder and rheology modifier, giving toothpaste its characteristic smooth body and consistency. It prevents the separation of water from the solid components of the paste, ensuring the toothpaste does not become coarse or separate from its tube shell. CMC's good stability and suitable viscosity make toothpaste more fresh and pleasant to use. Its excellent compatibility with other toothpaste ingredients is also a key advantage. High-purity, toothpaste-grade CMC typically has a good white appearance and favorable rheological properties, facilitating the creation of clear or opaque pastes.

CMC's utility extends to the textile industry, particularly in printing applications. It is used as a printing paste thickener and sizing agent. When used as a printing material for dye-trimming processes, CMC improves the hydrophilic force and osmosis force of the dye material. This leads to more even dye penetration and distribution, significantly reducing chromatism (color variations) and improving the quality and consistency of printed fabrics.
