Washing powder and soap powder viscosity reduction synergist

Abstract

The invention discloses washing powder and a soap powder viscosity reduction synergist. The soap powder viscosity reduction synergist is characterized by being an amphipathic polymer copolymerized by the following monomers under the action of assistants: (a) 10-90 percent of carbpxyl-containing unsaturated monomer and / or salts thereof; (b) 1-80 percent of polyether-containing chain segment unsaturated monomers; (c) 0-70 percent of hydrophobic group-containing unsaturated monomer; and (d) 0-50 percent of acid diffluent water-soluble unsaturated monomer, wherein the weight percentage summation of all monomers is 100 percent. The invention also discloses a detergent addictive and a detergent with the washing powder and the soap powder viscosity reduction synergist. The soap powder viscosity reduction synergist can play roles of reducing the viscosities of the washing powder and soap powder dusting slurry and improving the washing effect and the synergism, thereby meeting the demand of the current market.

Description

technical field [0001] The invention belongs to the technical field of synthesizing functional polymers in macromolecular chemistry, and in particular relates to a viscosity-reducing synergist for washing powder and soap powder, and a detergent additive and detergent containing the viscosity-reducing synergist. Background technique [0002] Due to the importance of environmental protection, phosphorus-free, concentrated, and soap-based detergents have become the mainstream direction of detergent development, but they are still restricted by some factors. Phosphorus-free detergents perform poorly in terms of decontamination and anti-ash deposition, and need to use more efficient detergent boosters to promote their development; concentrated detergents also have a greater demand for high-efficiency detergent boosters; and soap-based washing Agents, especially soap-based detergents, have the problem of sticky slurry during the powder spraying process, and the washing performance...

This type of detergent builder has some help in reducing the viscosity of ordinary laundry powder slurries, but not significantly; it is even worse in reducing the viscosity of soap-based laundry powder slurries

[0004] Patent CN101144053A describes a dispersant for reducing the viscosity and stabilizing effect of washing powder slurry. The dispersant is obtained by copolymerization of unsaturated organic acid and unsaturated polyether monomer. The viscosity of the slurry increases the stability of the system, but its impact on the washing performance of the detergent is unknown and needs further research

[0005] Patent CN100564504C describes a copolymer prepared by the copolymerization of monomer components containing alkylene imine unsaturated monomers and other monomers as a detergent builder. The copolymer shows good detergent build-up The effect can significantly improve the detergency and anti-repollution of the detergent, but the structure of the copolymer is relatively complex, the cost is high, and the application in the detergent may be limited. At the same time, its effect on the viscosity of the washing powder slurry The impact is unknown, and it cannot be used as a viscosity-reducing synergist for laundry detergent for the time being
