Embodiment 1

[0027] A high-efficiency color-protecting laundry detergent is characterized in that it is formed by uniformly mixing the following components:

[0028]

[0029] Among them: the multi-component surfactant is a mixture of anionic surfactant and nonionic surfactant at a mass ratio of 1:1, and the anionic surfactant is sequentially selected from sulfonate-type surfactants, sulfuric acid-type surfactants and carboxylic acid-type surfactants. Surfactant; non-ionic surfactants are sequentially selected from fatty alcohol polyoxyethylene ether and modified ethoxylated species;

[0030] The color-protecting agent is poly-4-vinylpyridine nitrogen oxide. The physical and chemical properties of the color-protecting agent are as follows: degree of oxidation ≥ 90%, active ingredient 33%-37%, Gardner chromaticity 6-13, viscosity 40cps-80cps, pH Value 4.0~5.0;

[0031] Chelating agent selects sodium citrate for use;

[0032] The fluorescent whitening agent is selected from the stilbene ...

Embodiment 2

[0054] A high-efficiency color-protecting laundry detergent is characterized in that it is formed by uniformly mixing the following components:

[0055]

[0056]

[0057] Wherein: multi-element surfactant selects the mixing of anionic surfactant and nonionic surfactant with mass fraction 1:3, and the selection material of anionic surfactant and nonionic surfactant is all the same with embodiment 1;

[0058] The selected materials and preparation methods of other components are the same as in Example 1.

Embodiment 3

[0060] A high-efficiency color-protecting laundry detergent is characterized in that it is formed by uniformly mixing the following components:

[0061]

[0062] Wherein: multi-element surfactant selects the mixing of anionic surfactant and nonionic surfactant with mass fraction 3:1, and the selection material of anionic surfactant and nonionic surfactant is all the same with embodiment 1;

[0063] The selected materials and preparation methods of other components are the same as in Example 1.

Abstract

The invention mainly relates to the field of washing compositions with a surface active compound as a base material, specifically to a highly-efficient color-protecting liquid laundry detergent and apreparation method thereof. The highly-efficient color-protecting liquid laundry detergent is characterized by being prepared from the following components by uniform mixing in terms of mass percent concentration (%): 15% to 30% of a multi-element surfactant, 0.1% to 3% of a color-protecting agent, 1% to 5% of a chelating agent, 0% to 5% of a fluorescent whitening agent, 0.1% to 1% of a preservative, 0.1% to 1% of an essence and 0.1% to 1% of a thickening agent, with the balance being water. The highly-efficient color-protecting liquid laundry detergent provided by the invention has good washing effect, reduces the loss of fabric color, and prevents colors from crossing in fabric washing.

Description

technical field [0001] The invention relates to the field of cleaning compositions mainly based on surface active compounds, in particular to a high-efficiency color-protecting laundry detergent and a preparation method thereof. Background technique [0002] With the improvement of living standards, consumers have more and more demands for laundry detergent. In addition to the basic washing function, they also expect it to protect and care for fabrics. In daily washing, colored fabrics often fade, and white and dark fabrics are mixed with colors. The most effective way is to add a color-protecting agent that can protect the color into the laundry detergent formula. There are two types of commonly used color-retaining agents, non-ionic and cationic, but the color-retaining effect of non-ionic color-retaining agents is limited, and most cationic color-retaining agents have compatibility problems with anionic surfactants and fluorescent whitening agents.
