Solubility of CMC Carboxymethyl cellulose is mainly based on the composition.
Carboxymethyl cellulose CMC is a water-soluble material and it also soluble in either hot or cold water. It is insoluble in organic solvents but will dissolve in miscible solvents as ethanol or acetone. Its viscosity will not increase with temperature.
It 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. It is the substituted product of cellulosic carboxymethyl group. According to their molecular weight or degree of substitution,solubility of CMC Carboxymethyl cellulose completely changess and 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
Carboxymethyl cellulose (CMC) is not only valued for its solubility but also for its versatility in forming colloidal solutions that exhibit a range of functional properties. These properties include adhesive, thickening, and emulsifying capabilities, making CMC an essential ingredient in various industrial applications. In the food industry, for instance, CMC is used to stabilize and thicken products such as ice cream, sauces, and dressings, ensuring consistent texture and preventing separation. Its ability to form films also makes it useful in packaging applications where it acts as a protective barrier.
Moreover, the compatibility of CMC with other water-soluble gums and resins enhances its utility across different formulations. This compatibility allows for the customization of viscosity and texture in products, catering to specific needs in industries like cosmetics, where CMC is used to create smooth, spreadable creams and lotions. In the pharmaceutical sector, CMC’s non-toxic and inert nature makes it a reliable excipient in drug formulations, where it aids in controlling the release of active ingredients. Additionally, its role in the oil industry includes enhancing the efficiency of drilling fluids by providing the necessary rheological properties for effective drilling operations.
