Carboxymethyl Cellulose CAS#9000-11-7
Carboxymethyl cellulose (CMC) is a key cellulose ether and a water-soluble anionic polymer produced by chemical modification of natural fibers. It dissolves readily in both cold and hot water and exhibits valuable physicochemical properties, including excellent emulsifying and dispersing abilities, resistance to degradation, and physiological inertness, making it a widely used natural polymer derivative.

Product Usage
CMC serves as an effective thickener and stabilizer, enhancing food texture and mouthfeel by increasing viscosity—for example, providing a smooth texture in ice cream and preventing whey separation in yogurt. It also works synergistically with proteins and starches to prevent ingredient separation and extend shelf life. In low-fat foods, CMC can replace fat, mimicking the creamy texture of full-fat products.
Company Profile
