Bath lotion with N-lauroyl-L-alanine sodium salt or potassium salt as surfactant

Abstract

The invention discloses bath lotion with N-lauroyl-L-alanine sodium salt or potassium salt as a surfactant, which comprises the following components by mass: 10%-20% of N-lauroyl-L-alanine sodium salt or potassium salt; 1.0%-5.0% of potassium cocoyl glutamate; 1.0%-3.0% of sodium lauroamphoacetate; 1.0%-5.0% of cocoalkyl-betaine; 1.0%-3.0% of 50% sodium pyrrolidonecarboxylate solution; 1.0%-2.0% of glycerol monolaurate; 70%-80% of water; 0.1%-0.5% of hydrolyzed hyaluronic acid; 1.0%-3.0% of phenoxyethanol, benzoic acid, dehydroacetic acid (and) ethylhexylglycerin; 1.0%-3.0% of propylene glycol, water (and) nettle extract; 1.0%-2.0% of perfume; a proper amount of citric acid for keeping a DI-I value of the product being 5.5-6.5. 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 shower gel, in particular to a shower gel containing N-lauroyl-L-alanine sodium or potassium salt as a surfactant, belonging to the technical field of shampoos. Background technique [0002] Surfactants are needed in shower gels. Although ordinary surfactants have good characteristics and are widely used in production and life, their biodegradability and ecological compatibility are poor, which will harm the ecological environment. As people pay more and more attention to the safety, mildness and environmental protection requirements of various products, 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. Due to the amino acid skeleton in the molecule, in addition to the performance of other series of surfactants, they also have other unique functions,...

AI Technical Summary

Problems solved by technology

[0004] There are more than 200 kinds of amino acids, and 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 immature in production in my country, and the demand is mainly dependent on imports, which are expensive and restrict the development of domestic shower gels.
