Stabilizing agents carboxymethylcellulose sodium

Whatever the type of soil removed, once this soil is detached from the substrate, barriers must be set up to inhibit reattachment or redeposition. The chemicals used to achieve this are known as antiredeposition agents. Surfactants can achieve this by adsorbing onto the detached soil and setting up electrostatic and steric barriers to redeposition. For example, anionic surfactant can adsorb onto a particle to induce a negative charge, and the resultant repulsion of these particles from negatively charged cotton. Nonionic surfactants can adsorb onto the surface of oily soil droplets, form a macroemulsion, and set up steric barriers to redeposition. In practice, water-soluble polymers (e.g., sodium carboxymethylcellulose) are used for antiredeposition, but the mechanisms are electrostatic and steric stabilization. 

Sodium carboxymethylcellulose is readily soluble in water and is insoluble in organic solvents. The material is used as a soil-suspending agent in detergents, suspending agent in latex paints and as an adhesive it is also used as a stabilizer in food products such as ice cream.
