Abstract

The invention relates to an environment-friendly high-efficiency laundry detergent and a preparation method thereof. At present, the dirt-removing power of the laundry detergent is improved generally by increase the content of surfactant in components, but the emission amount of active substances in the discharge process of the laundry detergent can be increased to cause environment burden. The environment-friendly high-efficiency laundry detergent comprises the following components in percentage by weight: 2-8% of fatty alcohol-polyoxyethylene ether sulfate, 2-6% of fatty alcohol-polyoxyethylene ether, 1-3% of anion dimeric surfactant, 0.5-3% of organic amine, 0.5-4% of potassium hydroxide, 0.5-2% of sodium citrate, 0,05-0.5% of essence and the balance of water. The laundry detergent adopts a green and natural anion bimeric surfactant' compared with the traditional surfactant, the green and natural anion bimeric surfactant has the advantages that synthetic raw materials are natural regenerable resources, the the synthetic process is green, environment-friendly and safe, biodegradability is good, and performances are excellent, the dirt-removing power of the laundry detergent can be obviously improved after a small amount of anion bimeric surfactant is added.

Description

technical field [0001] The invention relates to a laundry detergent, in particular to an environment-friendly and high-efficiency laundry detergent and a preparation method thereof. Background technique [0002] With the development of society, technology and economy, and the improvement of people's living consumption level, the demand for detergents is increasing, and the development speed of detergents is very fast. In 1985, the total amount of washing products in my country was only 1 million tons, and in 2011 it reached 8.51 million tons. The rapid growth of detergent consumption has exacerbated the resulting environmental pollution. In recent years, the Chinese government has continuously advocated development concepts such as green, environmental protection, energy conservation, and emission reduction. The concepts of green environmental protection, energy conservation, and emission reduction have been deeply rooted in the hearts of the people. It is an effective wa...
