Sodium CarboxyMethylCellulose(CMC)
Sodium CarboxyMethylCellulose is an important cellulose ether, It is obtained by chemical modification of natural fiber and is a polyanion compound with good water-solubility, easily soluble in both cold and hot water, Sodium CarboxyMethylCellulose has many unusual and valuable physical and chemical characteristics such as emulsifying disparity, solid disparity, resistance to decay, being physiologically harmless etc. and is widely used as a natural macromolecular derivate.
Sodium Carboxymethyl Cellulose | Cellulose Gum
Brief introduction
Sodium Carboxymethyl Cellulose (Cellulose Gum or CMC) is extracted from wood pulp and pure cotton cellulose. Sodium Carboxymethyl Cellulose can be divided into industrial grade and food grade. The industrial-grade Sodium Carboxymethyl Cellulose can be further divided into technical-grade and semi-purified Sodium Carboxymethyl Cellulose. And the technical-grade Sodium Carboxymethyl Cellulose (or crude CMC) generally has purity less than 80%; the semi-purified Sodium Carboxymethyl Cellulose has purity ranging from 80% to 95%; the purified Sodium Carboxymethyl Cellulose has purity more than 99.5%. Only purified Sodium Carboxymethyl Cellulose is safe to eat. SidleyCel Sodium Carboxymethyl Cellulose can fully meet FCC IV standards, with quality and stability.

SidleyCel® CMC has benefits like good acid resistance, salt tolerance, high transparency, less free cellulose and gel particles, fast dissolution and good fluidity.
- CMC can prevent the protein in yoghurt from coagulating and delamination.
- CMC can make water, fat and protein well mixed, dispersed and emulsified in ice cream, avoid ice crystals, improve taste and keep uniformity of final products.
- CMC can ensure the stability of acid drinks and extend its shelf life due to its good degree of substitution.
- CMC itself has no calorific value and is a good choice for manufacturing low-calorie foods.
