Carboxymethyl cellulose sodium is a kind of ionic cellulose ether undergoing alkalization of cellulose by etherification chloroacetate, and washing. Cause of Quality differentiation: 1, raw variety, quality and dispersion 2, production equipment, formulation and process of diversification, differentiation 3, the supply organization and the complexity of the supply process

Carboxymethyl cellulose sodium is a product instead of  cellulose carboxymethyl group. According to their molecular weight or degree of substitution can be completely dissolved or insoluble polymer, which can be used as a weak acid cation exchanger for the separation of neutral or basic proteins. Carboxymethyl cellulose can form high viscosity colloid solution, adhesion, thickening, mobility, emulsifying, shaped, water, protective colloid, film forming, acid, salt, suspension characteristics and physiological harm, and therefore are widely used in the production of food, medicine, daily chemical, petroleum, paper, textile, construction and other fields.
