[0002] Sodium lauroyl sarcosinate is an anionic surfactant, which is colorless to slightly yellow transparent liquid, has good foaming performance, rich and stable foam, good decontamination and antistatic ability, high tolerance to hard water and electrolyte, and can be matched with other anionic surfactants and nonionic surfactants to enhance various functions. Sodium lauroyl sarcosinate is a protein-like substance, which has good softening effect on skin and hair, can form a protective film on skin and hair, reduce the damage of irritating ingredients in cleaning agent formula to skin and hair, has weak degreasing effect, does not damage skin, has no friction feeling of soap during cleaning, and has mild bactericidal effect. It is widely used in hand washing liquid, shower gel, shampoo, foam shaving product, oral cleaning product, facial cleanser, soap-based facial cleanser, facial cleanser and the like.

[0003] The production process of sodium lauroyl sarcosinate mainly includes steps such as condensation reaction, acidification reaction and neutralization reaction. In the condensation reaction, the sarcosinate sodium aqueous solution and the reaction solvent are added into the reaction kettle, then the lauroyl chloride and the sodium hydroxide aqueous solution are added, and after 2-5 hours of reaction, the lauroyl sarcosinate crude product is obtained. When the lauroyl sarcosinate crude product is discharged, the reaction kettle for condensation reaction stops working, and only after the discharge is completed, the next feeding and condensation reaction can be carried out, so that the condensation reaction cannot be continuously and uninterruptedly carried out, and the production efficiency is affected. Therefore, the existing technology has the problem of discontinuous production. UTILITY MODEL CONTENTS
