Detailed Description

Physical and chemical properties: 1. Appearance: White free flowing powder; 2. Viscosity: 100-4000mPas; 3. Purity: 95%-99.5% 4. Degree of substitution: 0.60-1.0; 5. Moisture: 8.0%max; 6. PH value (1% aqueous soln): 6.0-8.5. Used in food industry has a good effect in thickening, stability, retaining water and so on. CMC is used in food science as a viscosity modifier or thickener, and to stabilize emulsions in various products including ice cream. As a food additive, it has E number E466. It is also a constituent of many non-food products, such as K-Y Jelly, toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing and various paper products. It is used primarily because it has high viscosity, is non-toxic, and is non-allergenic. In laundry detergents it is used as a soil suspension polymer designed to deposit onto cotton and other cellulosic fabrics creating a negatively charged barrier to soils in the wash solution. CMC is used as a lubricant in non-volatile eye drops (artificial tears). Sometimes it is methyl cellulose (MC) which is used, but its non-polar methyl groups (-CH3) do not add any solubility or chemical reactivity to the base cellulose.
