Problems solved by technology

Detergents containing peroxides must be washed at a temperature higher than 60°C in order to fully exert the effect of peroxides. Experiments have shown that only a small part of the peroxides will play a role in washing at temperatures lower than 60°C. Function, in order to achieve the expected bleaching effect, the formulation engineer will increase the amount of peroxide added in the formulation, which will inevitably increase the cost of the formulation

Abstract

The invention discloses a detergent composition containing a low-temperature bleaching and activation system, which is prepared from the following components in percentage by mass: 0.05-6.0% of activation agent synergist, 0.1-10.0% of activation agent, 0.1-20.0% of peroxide, 1.0-30.0% of anionic surfactant, 0.5-15.0% of nonionic surfactant, 0.5-30.0% of soft water assistant, 1.0-30.0% of other assistants and the balance of filler. According to the invention, the novel activation synergist is added into the detergent composition, so that the activation efficiency of the conventional activation agent is greatly enhanced; and the detergent composition has favorable bleaching and washing effect at a low washing temperature.

Description

technical field [0001] The invention relates to a detergent composition, which belongs to the technical field of daily chemical washing products, in particular to a detergent composition with good bleaching and washing effect under low-temperature washing. Background technique [0002] Peroxide bleach has a good removal effect on colored dirt and is safe and environmentally friendly. This technology has been widely used in Europe, America, Japan, and South Korea. In recent years, washing products containing peroxide bleaches have also appeared in China. As more and more consumers realize the advantages of peroxide bleaching technology, detergents containing peroxides have been developed to a certain extent. [0003] The extreme temperature dependence of peroxide bleaches is a common problem in the industry. Detergents containing peroxides must be washed at a temperature higher than 60°C in order to fully exert the effect of peroxides. Experiments have shown that only a smal...
