Novel brightening agent and washing powder composition with same

Abstract

The invention discloses a novel brightening agent and a washing powder composition with the same, and relates to the technical field of daily chemical washing products. The novel brightening agent isobtained by drying slurry, and the slurry is prepared from 0.1-10.0% of a coloring agent, 1.0-30.0% of a binder, 5.0-40.0% of an additive and 60.0-80.0% of process water. The washing powder composition is prepared from, by mass percentage, 1.0-30.0% of a surfactant, 20.0-85.0% of an auxiliary agent and 0.1-10.0% of the novel brightening agent. The brightening agent has the advantages that the disintegration speed is high, the coloring agent can be quickly dispersed in a solution, a fabric is uniformly colored in the washing process, and the fabric is prevented from being partially excessivelycolored. The washing powder composition has the advantages that under the low-temperature condition, the fabric has a brightened effect after being washed once, meanwhile, the brightening effect on the fabric is uniform, and the excessive coloring phenomenon cannot occur after washing is conducted multiple times; the fabric cannot be damaged in the brightening process by using brightening washingpowder, and the treated fabric can also show a good brightened effect without ultraviolet light rays.

Description

technical field [0001] The invention relates to the technical field of daily chemical cleaning products, in particular to a novel whitening agent and a washing powder composition containing the whitening agent. Background technique [0002] After the fabric has been used for a period of time, it often turns dark yellow due to old oxidation, stain erosion and other reasons. In order to whiten fabrics, people usually use the following methods for treatment: [0003] 1. Chemical bleaching method. The mechanism of this method is to fade the color of the fabric surface by redox reaction with pigment stains, so as to achieve the effect of whitening the fabric. Chemical bleaching method has different degrees of bleaching and fading of colored fabrics. , but also has a damaging effect on silk, fur and other fabrics; [0004] 2. Fluorescent whitening agent whitening method. Fluorescent whitening agent is an organic compound that can absorb ultraviolet light and excite blue or blue-...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to solve the problems in the existing fabric whitening process that the colored fabrics are easy to fade, the fabric is easy to be damaged, the whitening effect of single washing is not obvious, the coloring is too much after multiple washings, and the color of the fabric is not brightened under the light without ultraviolet light. The problem of reducing the whitening effect of fabrics, providing a new technical solution for fabric whitening
