Dialyse it for 48hours against distilled water and freeze-dry if a solid is required.
Carboxymethyl cellulose (CMC) is tackifier, at room temperature, it is non-toxic tasteless white flocculent powder, it is stable and soluble in water, aqueous solution is neutral or alkaline transparent viscous liquid, it is soluble in other water-soluble gums and resins, it is insoluble in organic solvents such as ethanol. Carboxymethyl cellulose is the substituted product of cellulosic carboxymethyl group. According to their molecular weight or degree of substitution, it can be completely dissolved or insoluble polymer, the latter can be used as the weak acid cation of exchanger to separate neutral or basic proteins.
Carboxymethyl cellulose can form highly viscous colloidal solution with adhesive, thickening, flowing, emulsifying, shaping, water, protective colloid, film forming, acid, salt, suspensions and other characteristics, and it is physiologically harmless, so it is widely used in the food, pharmaceutical, cosmetic, oil, paper, textiles, construction and other areas of production.
It is used in cigarette adhesive, fabric sizing, footwear paste meal, home slimy. It is used in interior painting architectural, building lines melamine, thickening mortar, concrete enhancement. It is used in refractory fiber, ceramic production molding bond. It is used in oil drilling, exploration address slurry thickening, reducing water loss, quality paper surface sizing. It can be used as soap and washing powder detergent active additives, as well as other industrial production on the dispersion, emulsification, stability, suspension, film, paper, polishing and the like. Quality product can be used for toothpaste, medicine, food and other industrial sectors.
CMC can significantly increase the viscosity of the solution as thickener, dispersion, emulsification, suspension, protective colloid and so on when it is dissolved in water, and it is physiologically harmless, it is widely used in the food, pharmaceutical, cosmetic, oil, paper, textiles, construction and other areas of production.
Use warm water or cold water when preparing the solution, and stir till it completely melts. The amout of added water depends on variety and the use of multiple requirements.
High viscosity sodium carboxymethyl cellulose (HV-CMC) is a white or slightly yellow fibrous powder, hygroscopic, odorless, tasteless, non-toxic, easy to ferment, insoluble in acids, alcohols and organic solvents, easily dispersed to form colloidal solution in water. It is reacted by the acid and fibrous cotton, it is mainly used for water-based drilling fluids tackifier, it has certain role of fluid loss, it has strong salt and temperature resistance especially.
