e: zoe at 0311chem.com 1, a main physical and chemical properties, the CMC is a linear ion-polymer material, pure white or slightly yellow, fibrous powder, non-toxic, tasteless and soluble in hot and cold water to become transparent solution viscosity, Natural Rubber and general syntheic did not have many advantages, which are widely used in food processing, beverages, textiles, paper making, Oil drilling, daily chemicals, paint, tobacco, building materials, ceramics, Coil, detergents, and other industrial and unique thickener, binder, emulsifier, aquasorb, dispersion, suspensions, puffing sexual fixing agent, retarders in all sectors play their role, commonly known as the "industrial MSG" two, the use of a small amount of water infiltrating it, and then add water, stirring as necessary preparation concentration of the solution. For other ingredients, excipients and will be the best blending of CMC, in the solution of high-speed stirring gradually input can be fast dissolving. We should also be careful in high-temperature, the viscosity will reduce the temperature rise, as CMC easily absorb moisture users attention to packaging intact, Moistened products to avoid dissolution.
