Problems solved by technology

With the continuous improvement of people's quality of life, the requirements for laundry detergent are also constantly increasing, requiring it to have better biocompatibility, less harmful substance residues, lower skin irritation and resistance to high-grade fabrics such as silk. No damage, however, traditional laundry detergent formulations such as CN101993791A, CN101457180A generally use relatively large sulfate or sulfonate anionic surfactants as active substances, and use alkanolamides that may contain nitrosamine carcinogens 6501 is used as a thickener, so it is difficult to meet the above requirements at the same time

Abstract

A mild safe liquid laundry detergent comprises the following raw materials in weight percents: 1.5-5.0% of fatty alcohol-polyoxyethylene ether, 5.0-12.0% of glucoside, 1.5-5.0% of alcohol ether carboxylate, 0.1-1.05 of thickening agent, 0.1-5% of other auxiliaries, and rest being de-ionized water. The mild safe liquid laundry detergent is mild, safe, and suitable for hand wash.

Description

technical field [0001] The invention belongs to a laundry liquid, in particular to a mild and safe laundry liquid and a preparation method thereof. Background technique [0002] Laundry liquid is a personal laundry washing product that has emerged and developed rapidly in recent years. Compared with washing powder, laundry liquid has the advantages of easy dissolution, low energy consumption, and high active substance content. It is the future development direction of laundry detergents. With the continuous improvement of people's quality of life, the requirements for laundry detergent are also constantly increasing, requiring it to have better biocompatibility, less harmful substance residues, lower skin irritation and resistance to high-grade fabrics such as silk. No damage, however, traditional laundry detergent formulations such as CN101993791A, CN101457180A generally use relatively large sulfate or sulfonate anionic surfactants as active substances, and use alkanolamide...
