Preparation method of amino acid surfactant

Abstract

The invention relates to a preparation method of a production of an amino acid surfactant, in particular to a preparation method of a high-purity N-acyl amino acid surfactant, and belongs to the technical field of surfactant preparation. According to the preparation method, crystallization and recrystallization are conducted without an organic solvent, the characteristics that the N-acyl amino acid surfactant is easy to foam, and reaction by-products sodium chloride and the like are not likely to foam are fully utilized, and the components of active matter of the surfactant generate foam through a foam generating device, so that the purpose of separating the surfactant from impurities is achieved, the product with the high purity is obtained, and the environment and health problems caused by conducting crystallization and recrystallization with the organic solvent previously are solved.

Description

technical field

[0001] The invention relates to a preparation method of an amino acid surfactant product, in particular to a preparation method of a high-purity N-acyl amino acid surfactant, and belongs to the technical field of surfactant preparation. Background technique

[0002] N-acyl amino acid series products are anionic surfactants with excellent performance formed by the condensation of amino acids, which are extremely gentle on the skin and will not cause allergies and phototoxicity; have excellent adaptability to hard water; have good biodegradability and safety , can be decomposed into amino acids and fatty acids in the human body for absorption and utilization; it has good cleaning power and foaming power, is non-toxic and harmless to the human body, has no peculiar smell, is soft and non-irritating, and can stabilize the activity of enzymes. It is a high-grade shampoo and The main raw material of the shower gel can be firmly adsorbed on the hair and skin, increa...
