Sodium carboxymethyl cellulose
CAS NO 9004-32-4
Alias：CMC
Molecular formula：C6H7O2(OH)2CH2COONa
Molecular weight：0
Structural formula：
1.Performance and use
The properties of carboxymethyl cellulose sodium are as follows: 1. Moisture absorption characteristics. Its degree of moisture absorption is related to atmospheric temperature and relative humidity. When it reaches equilibrium, it no longer absorbs moisture. CMC aqueous solution has excellent properties such as adhesion, thickening, emulsification, suspension, film formation, colloidal protection, moisture retention, resistance to enzymatic hydrolysis, and metabolic inertness. When CMC aqueous solution encounters tin, silver, aluminum lead, iron, copper, and certain heavy metals, precipitation reactions occur; When CMC aqueous solution coexists with calcium, magnesium, and salt, no precipitation occurs, but the viscosity of CMC aqueous solution is reduced. When CMC aqueous solution encounters acid, acidic CMC precipitates. But acid resistant CMC has a certain resistance to acidic solutions.
Sodium carboxymethyl cellulose can be used as a thickener, stabilizer, and emulsifier. The specific application areas are as follows: 1. The application of CMC in food. Edible CMC has characteristics such as thickening, emulsification, shaping, water retention, and stability. Adding CMC to food can reduce production costs, improve food quality, enhance food taste, and extend the shelf life of food. It is an ideal food additive for the food industry and can be widely used in the production of various solid and liquid beverages, canned foods, candies, pastries, meat products, biscuits, instant noodles, rolls, quick cooked foods, frozen snack foods, as well as soy milk, yogurt, peanut milk, fruit tea, fruit juice and other foods. CMC has different uses and dosages in different foods. 2. The use of CMC in the pharmaceutical industry: It can be used in the pharmaceutical industry.
