PVP has anti fouling and re precipitation properties and can be used to prepare transparent liquids or heavy fouling detergents. Adding PVP to detergents has a good anti discoloration effect and can enhance cleaning ability. When washing fabrics, it can prevent synthetic detergents from irritating the skin, especially synthetic fibers. This performance is more outstanding than carboxymethyl cellulose (CMC) detergents. PVP can be compounded with borax as an effective ingredient in the formulation of phenolic disinfectant cleaning agents. The detergent composed of PVP and hydrogen peroxide has the functions of bleaching and killing bacteria.
