Abstract

The invention discloses an environment-friendly composite laundry detergent and a preparation method thereof, and belongs to the technical field of daily chemicals. The composite laundry detergent isprepared from the following components in percentage by mass: 5 to 20% of allyl alcohol polyoxyethylene ether sulfate; 3% to 15% of dialkylated chitosan sulfate; 5% to 20% of a nonionic surfactant; 9%to 15% of a Chinese honey locust fruit extract; 2% to 5% of lemon essence; 0.9% to 1.5% of sodium silicate; 1% to 2.5% of a re-deposition resistant agent; 0.25% to 1.75% of a chelating agent; and thebalance being deionized water. The provided laundry detergent contains a specific anionic surfactant, and has the advantages of good low-temperature washing performance, low foam, easiness in rinsing, low irritation, biodegradability and the like.

Description

technical field [0001] The invention relates to an environment-friendly composite laundry liquid and a preparation method thereof, belonging to the technical field of daily chemicals. Background technique [0002] In recent years, the product structure of my country's washing products industry has been continuously optimized, and the proportion of liquid detergents has continued to rise, among which laundry detergent has the fastest development. In view of the increasingly prominent problems of resources and the environment, my country's light industry development plan proposes to adhere to the principle of ecological development, strengthen energy conservation, emission reduction and comprehensive utilization of resources, and devote itself to the technical research of formulas for low-foaming, easy-rinsing, energy-saving and water-saving detergents. [0003] The anionic surfactants used in traditional laundry detergents are mostly alkoxylate sulfate ester salts, but these ...
