Abstract

The invention relates to a laundry detergent. The laundry detergent comprises an A component, a B component and a C component, wherein the A component consists of sodium laureth sulfate, C12-16 alkylglucoside, sodium lauryl sulfate, cocoalkanoylamido propyl betaine, linoleamidopropyl ethyldimonium ethosulfate, octadecadienamide DEA, methylparaben and water; the B component consists of protease, sodium chloride, ethylene diamine tetraacetic acid and citric acid; and the C component consists of methylisothiazolinone and an essence. According to the laundry detergent, the protease is compatiblewith laurinol sodium sulfovinate and cocoalkanoylamido propyl betaine for use, so that the laundry detergent is little in thrill, soluble in water, more in foams and high in detersive power.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to a laundry detergent and a preparation method thereof. Background technique [0002] The main component of laundry detergent is a non-ionic surfactant, its structure includes a hydrophilic end and an lipophilic end, wherein the lipophilic end combines with the stain, and then separates the stain from the fabric through physical movement (such as hand rubbing, machine movement); at the same time, the surface The active agent reduces the tension of the water, so that the water can reach the surface of the fabric, so that the active ingredients can play a role; the technical content of the laundry detergent is higher, and it is convenient to add various active ingredients. After washing, the clothes will be fluffy, soft, smooth and shiny, and have The efficacy of sterilization and long-lasting fragrance, low comprehensive cost of use, are widely accepted by people. ...
