Abstract

The invention discloses laundry liquid and a preparation method thereof. The laundry liquid is prepared by the following materials in percentage by mass: 0.1 to 5.0 percent of oleophylic modified polymer, 0.2 to 5.0 percent of carboxylic acid polymer, 1 to 25.0 percent of nonionic surfactant, 1 to 25.0 percent of anionic surfactant, 0.01 to 1.5 percent of enzyme, 0.1 to 15.0 percent of enzyme stabilizer, 0.5 to 8.0 percent of foam control agent, 0.5 to 10 percent of other auxiliary agents and the balance of water. By the preparation method of the laundry liquid, the production time can be reduced by about 30 percent, and the laundry liquid is efficiently produced; and the prepared laundry liquid has high detergency to mud and oil stains and high stain redeposition resistance.

Description

technical field [0001] The invention relates to the technical field of detergents, in particular to a laundry detergent and a preparation method thereof. Background technique [0002] In my country, with the improvement of people's living standards, consumers are increasingly favoring the use of laundry detergent with good solubility. Compared with washing powder, laundry detergent has the characteristics of mildness, easy dissolution, and low energy consumption. Laundry liquid started late in my country, and its market share is still very low, but the laundry liquid market has maintained rapid growth in recent years. At present, the commercially available laundry detergent in my country is still dominated by ordinary laundry detergent, and the active substance content generally does not exceed 25%. In developed countries such as Europe, America and Japan, concentrated laundry detergent is the main product, and the active substance is generally more than 25%. 2 times conce...
