Hair shampoo with N-lauroyl-L-alanine sodium salt or potassium salt as surfactant

Abstract

The invention discloses hair shampoo with N-lauroyl-L-alanine sodium salt or potassium salt as a surfactant, which comprises the following components by mass: 70%-80% of water; 10%-20% of a surfactant of N-lauroyl-L-alanine sodium salt or potassium salt; 1.0%-5.0% of a foaming agent of sodium methyl cocoyl taurate; a proper amount of an acidic component of citric acid for keeping a product PH value of 5.5-6.5; 1%-2% of silicone resin of polydimethylsiloxane, vinyl polydimethylsiloxane cross-linked polymer; 0.5%-1.0% of a thickening agent of hydroxypropyl dimethyl cellulose; 0.5%-1.0% of hydroxyethyl cellulose; 0.5%-1.0% of hydroxypropyl cellulose; 0.5%-1.5% of sodium chloride; 0.5%-1.5% of water retaining agents of panthenol, fatty alcohol or nut oil; 0.3%-0.5% of preservatives of urea formaldehyde or Iodopropynyl butylcarbamate or isothiazolinone and sodium benzoate; and 0.3%-0.5% of essence. The invention has the following advantages of: strong decontamination capability, very good compatibility, green and environmental protection, less skin irritation, and low cost.

Description

technical field [0001] The invention relates to a hair shampoo, in particular to a hair shampoo containing N-lauroyl-L-alanine sodium salt or potassium salt as a surfactant, and belongs to the technical field of shampoo products. Background technique [0002] In shampoo, surfactants are needed. Although common surfactants are widely used in production and life because of their good characteristics, their biodegradability and ecological compatibility are poor, which will cause harm to the ecological environment. . As people pay more and more attention to the safety, mildness and environmental protection requirements of various products, the research and development of multifunctional and high-quality environmentally friendly surfactants has become the main direction of the surfactant industry. [0003] Amino acid surfactants are surfactants based on biological substances. Because of the amino acid skeleton in the molecule, they not only have the properties of other series of...

AI Technical Summary

Problems solved by technology

[0004] There are more than 200 kinds of amino acids, and currently only a dozen basic amino acids can be used to synthesize N-acyl amino acid surfactants. Now the amino acids and their salts are commonly used in the synthesis of N-lauroyl amino acid surfactants for cosmetics. As long as there are sarcosine, glutamic acid, serine, lysine, leucine, etc., its application and research reached a climax in the 1970s. At present, this type of product has been widely used abroad, and the more influential ones are Hamposyl from the United States, Medialan from Germany, and Amisoft from Japan are still immature in production in my country, and the demand is mainly dependent on imports, which are expensive and restrict the development of domestic shampoos, etc.
