Carboxymethyl cellulose (CMC) is a tackier, non-toxic and tasteless white flocculent powder at room temperature, stable performance, easy to dissolve in water, its aqueous solution is neutral or alkaline transparent viscous liquid, soluble in other water-soluble adhesives and resins, insoluble in ethanol and other organic solvents. Carboxymethyl cellulose is a carboxymethyl group substitution product of cellulose. Depending on its molecular weight or degree of substitution, it can be a completely dissolved or insoluble polymer, the latter can be used as a weak acid type cation exchanger for the separation of neutral or basic proteins.
Carboxymethyl cellulose can form high viscosity colloids, solutions, adhesion, thickening, flow, emulsification and dispersion, shape, water retention, protection of colloids, film forming, acid resistance, salt resistance, turbidity and other characteristics, and physiological harmless, so it is widely used in food, medicine, daily chemical, petroleum, paper making, textile, construction and other fields of production.
