CMC (Sodium Carboxymethyl Cellulose)
CMC (Sodium carboxymethyl cellulose), CAS NO. is: 9004-32-4, also known as Sodium CMC, CMC Na, is an organic substance, a carboxymethylated derivative of cellulose, and the most important ionic cellulose gum. The obtained anionic polymer compound is a white fibrous or granular powder, odorless, tasteless, hygroscopic, and easily dispersed in water.
Applications:
In the food industry, Sodium carboxymethyl cellulose has a thickening and emulsifying effect and can be used to stabilize yogurt drinks; it has a water-retaining effect and can play a role in tissue improvement, and is used in meat products, bread, steamed buns and other foods. Sodium CMC has It has a certain gelling effect and can be used to make jelly and jam; it has film-forming properties and can be used to extend the shelf life of fruits and vegetables. CMC powder is also used in the production of ice cream, clarification of wine, and thickening of food flavorings.
CMC Na is widely used in the petroleum industry as well-drilling mud treatment agents, synthetic detergents, organic detergent builders, and used in textile printing and dyeing, daily chemical products, pharmaceutical industry, ceramic industry, industrial pastes, paper industry, etc. It is used as a flocculant in water treatment, used in wastewater sludge treatment.
