Karboksymetylcellulose

Karboksymetylcellulose (CMC) is a water-soluble cellulose derivative that is widely used in various industries due to its thickening, stabilizing, and emulsifying properties. It is produced by the alkaline treatment of cellulose, which introduces carboxymethyl groups onto the cellulose backbone. This modification enhances the solubility of CMC in water, making it suitable for applications in aqueous systems.

CMC is commonly used as a thickener and stabilizer in the food industry. It is often used in sauces, dressings, and beverages to improve texture and stability. In the pharmaceutical industry, CMC is used as a binder, disintegrant, and stabilizer in tablet formulations. It is also employed in the cosmetics industry as a thickener and stabilizer in creams, lotions, and gels.

In the oil and gas industry, CMC is used as a drilling fluid additive to improve rheological properties and reduce filtration. It is also used in the paper industry as a retention aid to improve the retention of fillers and pigments on the paper surface. Additionally, CMC is used in the textile industry as a sizing agent to improve the strength and durability of fabrics.

CMC is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food and pharmaceutical applications. However, it is important to note that the safety of CMC can vary depending on the specific application and the concentration used. Therefore, it is essential to follow proper safety guidelines and regulations when using CMC in various industries.
