Carboxymethyl cellulose (CMC) is a non-toxic and odourless white flocculent powder. It is stable and soluble in water. Its aqueous solution is a neutral or alkaline transparent viscous liquid, soluble in other water-soluble colloids and resins, and insoluble in organic solvents such as ethanol. CMC can be used as adhesives, thickeners, detergents, suspensions, emulsifiers, dispersants, stabilizers, sizing agents, etc. Sodium carboxymethyl cellulose (CMC) is the most productive, widely used and convenient product of cellulose ethers, commonly known as "industrial monosodium glutamate".
Use of CMC in detergent:
Carboxymethylcellulose CMC is a kind of surfactant with hydrophilic and hydrophobic groups, and it is an effective anti adsorption adsorbent. CMC has good thickening, dispersing and emulsifying effect after dissolving in water. It can adsorb oil particles in the oil, disperse oil suspension in water, disperse oil suspension in water, and hydrophilic film on the surface of the washed products, and prevent direct contact with the washed products. Therefore, it can use of CMC in detergent effect. Better, with a large market.
Especially when the detergent active substance, the adsorption capacity of CMC is more. CMC has a large number of negative charges and generates electrostatic repulsion force, which makes the suspended particles in oil disperse well in water. Anti-adsorbent phase with CMS, gum, polyvinylpyrrolidone, etc.
