Carboxymethyl Cellulose Polymer

Carboxymethyl cellulose (CMC) is an ether derivative of natural cellulose. It is a white or slightly yellow powder. It is a water-soluble anionic surfactant. It is odorless, tasteless, and non-toxic. It has excellent water solubility, viscosity, emulsification, diffusion, enzyme resistance, stability, and environmental friendliness. CMC is widely used in papermaking, textiles, printing and dyeing, petroleum, green agriculture, and polymers.

(I) CMC has good stability

In cold foods such as popsicles and ice cream, using CMC can control the formation of ice crystals, increase the expansion rate, maintain uniform and consistent tissue, resist melting, have a delicate and smooth taste, and whiten the color. In dairy products, whether it is flavored milk, fruit milk or yogurt, it can react with protein within the isoelectric point range of pH value (PH4.6) to form a complex structure, which is beneficial to the stability of the emulsion and improve the impedance of protein.

(II) CMC can be compounded with other stabilizers and emulsifiers.

In food and beverage products, general manufacturers use a variety of stabilizers, such as xanthan gum, guar gum, carrageenan, dextrin, etc., and emulsifiers such as monostearate glyceride, sucrose fatty acid esters, etc. for compounding. It can complement each other's advantages, play a synergistic role, and reduce production costs.

(III) CMC has pseudoplasticity
The viscosity of CMC is reversible at different temperatures. When the temperature rises, the viscosity of the solution decreases, and vice versa. When shear force exists, the viscosity of CMC decreases, and as the shear force increases, the viscosity decreases. These properties enable CMC to reduce the load of equipment and improve the homogenization efficiency during stirring, homogenization, and pipeline transportation, which is unmatched by other stabilizers.

Food industry: CMC is widely used as a thickener, stabilizer and water-retaining agent in the production of ice cream, yogurt, jelly, beverages and other foods. 
Petroleum industry: CMC is used as a fluid loss reducer and rheology control agent in oil drilling mud, which can effectively control the mud properties and ensure the smooth progress of drilling operations. 
Textile industry: CMC is used as a sizing agent and finishing agent for textiles, which can improve the strength, gloss and feel of the fabric. 
Papermaking industry: CMC is used as a sizing agent and surface sizing agent for paper, which can improve the strength, smoothness and printing performance of paper. 
Detergent: CMC is used as a dirt suspending agent and thickener in detergents, which can improve the washing effect and prevent dirt from redeposition. 
Pharmaceutical industry: CMC is used as a binder and disintegrant for tablets, as well as a thickener and suspending agent for drugs. 
Daily chemical industry: CMC is used as a thickener and stabilizer in daily chemical products such as toothpaste and cosmetics.
Other industries:
CMC is also widely used in ceramics, coatings, building materials and other industries.
