With the development of economy and the emphasis on personal hygiene, detergent products have been upgraded and extended, from detergent cream to detergent powder to detergent liquid. Detergent products are widely used in daily life, and they have been one of the necessities of people’s daily purchase. Whether it is conventional detergent products or the concentrated detergent liquid that is being used more widely now, CMC always plays an important role in the industry.
Why is CMC difficult to replace? Because CMC is a surfactant with hydrophilic groups and hydrophobic groups, and is a highly effective anti-adsorption adsorbent. When it is dissolved in water, it has good thickening, dispersing and emulsifying effects. It can absorb oil particles in oil, disperse the oil suspension and suspended matter in the oil in water so that it will be washed. The surface of the object is formed into a hydrophilic film and prevents direct contact with the object to be washed. It can also make the washing liquid have a certain viscosity, so that the solution state remains stable. Therefore, CMC is still a very important component in detergent powder and detergent liquid.
The role of CMC in detergent liquid is mainly to apply its properties of emulsification and protective colloids. The anions generated during the washing process can simultaneously make the surface of the laundry and the dirt particles negatively charged, so that the dirt particles are in the water phase. Phase separation, it repels the surface of the solid-phase laundry (the same charge repels), so it can prevent dirt from re-depositing on the laundry, keep white fabrics white, and colored fabrics bright in color.
In addition, CMC is an affordable chemical additive compared to other stabilizers and emulsifiers with lower price and stable characteristics. More importantly, CMC is a kind of green chemical product, with no pollution to environment, and no harm to human body.
