Sodium carboxymethyl cellulose(9004-32-4) is a water-soluble polymer. As a solution in water, it has thixotropic properties. It is useful in helping to hold the components of pyrotechnic compositions in aqucous suspension (e.g., in the making of black match). It is also an especially effective binder that can be used in small amounts in compositions, where the binder can intcrfere with the intended effect (e.g., in strobe compositions). However, its sodium content obviously precludes its use in most color compositions. Sodium carboxymethyl-cellulose is manufactured from cellulose by various process that replace some of the hydrogen atoms in the hydroxyl[OH] groups of the cellulose molecule with acidic carboxymethyl [-CH2CO.OH] groups,which are neutralized to form the corresponding sodium salt. Sodium carboxymethyl cellulose is white when pure; industrial grade material may be grayish-white or cream granules or powder.
1, Uniform molecular weight distribution.
2, High resistance to acid.
3, High resistance to salt.
4, High D.S, High transparency, low free fibers.
5, Low gel.
1, Thickening: Increasing viscosity, and enhance the stability of food products.
2, Water retention: CMC is a water binder, helps to increase shelf life of food.
3, Stability: stabilize protein, emulsification, prevent precipitation stratification, delay oil-water stratification.
4, Metabolic inertia: As a food additive is not metabolized and does not provide calories, fat, orprotein in the food.
