Application of CMC Sodium in Detergent

Application of CMC Sodium in Detergent

Natural cellulose is the most widely distributed and abundant polysaccharide in nature. At present, the modification technology of cellulose mainly focuses on etherification and esterification. Carboxymethylation is one of the etherification technologies. Carboxymethyl cellulose (CMC) is obtained by Carboxymethylation of cellulose. Its aqueous solution has the functions of thickening, film formation, adhesion, water retention, colloid protection, emulsification and suspension. It is widely used in petroleum, food, medicine, textile and paper industries, and is one of the most important cellulose ethers.


Sodium carboxymethyl cellulose uses in detergent:


Sodium carboxymethyl cellulose, as an excellent washing suspension and dispersant, can be widely used in phosphate-free detergents, detergents, soaps and other fields. CMC is widely used as a detergent assistant because of its excellent anti-fouling and re-deposition properties.


The concrete principle is that adding the detergent or soap of sodium carboxymethyl cellulose can disperse and suspend the dirt that enters the aqueous solution so that the dirt can be prevented from depositing on the clothes, and the powerful decontamination ability can effectively reduce the washing time and better maintain the cleanliness of the clothes. It can effectively maintain the colour of clothes, and clean clothes will be softer and more comfortable. For the use of detergent with CMC in hard water, the effect will be more obvious.
