CMC for detergents

CMC for detergents

Sodium carboxymethyl cellulose (CMC) is a surfactant with hydrophilic and hydrophobic groups, serving as a highly efficient anti-sorbent adsorbent. CMC exhibits excellent thickening, dispersing, and emulsifying effects when dissolved in water. It can adsorb oil particles in oil, disperse oil suspensions in water, disperse suspended matter in oil in water, and form a hydrophilic film on the surface of the objects being washed, preventing direct contact.

  • DESCRIPTION

  • CMC is primarily used to prevent dirt washed off by detergents from re-depositing on fabrics. Adding CMC to detergent production effectively thickens washing sizes or soaps and stabilizes the structure of the constituents. In detergents, CMC can serve as an anti-dirt redeposition agent, especially effective for hydrophobic synthetic fiber fabrics compared to carboxymethyl fiber.

Petroleum grade CMC serves as a water-soluble colloid in the drilling mud system, composing the drilling fluid. It exhibits a high water loss control capability, functioning as a filtrate reducer. At lower dosages, it effectively controls water loss while maintaining the mud's other properties. The mud cake formed is of high quality, firm, and tough. Moreover, CMC demonstrates excellent temperature resistance and superior salt resistance. It retains its ability to reduce water loss and maintain a certain rheological behavior even at specific salt concentrations. In both brine and aqueous solutions, the viscosity remains almost unchanged. This makes it particularly suitable for the demands of offshore drilling and deep wells.
