Sodium carboxymethyl cellulose (Carboxymethyl cellulose sodium,CMC-Na) is a polymer compound, with a variety of special functions and excellent industrial performance, widely used in cosmetics, food, pharmaceutical industry, textile, paper, oil exploration and other fields.

sodium carboxymethyl cellulose was originally developed by the United States a water absorbent chemical additives, used for thickening, emulsification, moisture, stability, enhanced adhesion and other properties. Sodium carboxymethyl cellulose is widely used in cosmetics, food, pharmaceutical industry, textile, paper making, oil exploitation and other fields due to its good support, water solubility, gelation and adsorption capacity. It is a widely used functional additive.

In the field of cosmetics, sodium carboxymethylcellulose is useful as an emulsifier, a thickener, a binder, and the like. CMC-Na has the advantages of strong affinity with the skin, no irritation to the skin, and low toxicity. CMC-Na can also be used in products such as eye shadow, powder and lipstick in cosmetics, because it can increase the dispersion and adhesion of pigments.

In the food field, sodium carboxymethyl cellulose can be used for thickening, suspending, emulsifying, stabilizing, increasing viscosity, reducing taste, etc. CMC-Na are widely used in food additives, food improvers, food preservation and other fields. CMC-Na can increase the stability of agricultural products during processing and transportation, extend the shelf life, and reduce food waste and starch use.

In the pharmaceutical industry, sodium carboxymethyl cellulose is mainly used for thickening preparations, stabilizing emulsions, flavoring preparations, and regeneration capabilities. CMC-Na can increase the water solubility of the drug, improve the efficacy and absorption, and make the drug more stable and easy to use. In addition, the CMC-Na has a wealth of pharmacological research and clinical application value, can be used for the treatment and prevention of a variety of diseases.

In the textile industry, sodium carboxymethyl cellulose can be used as fiber thickening, anti-linting, call dyeing, anti-static and improve fiber auxiliaries. CMC-Na are mostly used as thickeners and regulators in textile industry applications. Specific applications of CMC-Na include anti-linting, dyeing and printing, fabric processing, adhesion enhancement and molding production.

In the paper industry, sodium carboxymethyl cellulose is mainly used for modulating fiber suspension, paper making liquid, recycled fiber, thickening, improving paper strength, improving smoothness and surface gloss. CMC-Na, the physical properties of the paper can be greatly improved, such as strength, stretch, water resistance, etc., and the appearance of the paper can also be improved.
