Biosurfactant microemulsion production system for cosmetics, food, chemical engineering and agriculture

Abstract

The invention relates to a biosurfactant microemulsion production system for cosmetics, food, chemical engineering and agriculture. The biosurfactant microemulsion production system comprises a fermentation kettle for producing the biosurfactant by virtue of microbial fermentation, a fermentation liquor purifier for purifying and separating the fermentation liquor in the fermentation kettle and a biosurfactant storage tank for storing the purified biosurfactant, a cosurfactant storage tank, an alkaline liquor storage tank, a water phase storage tank and an oil phase storage tank which are used for storing a cosurfactant, an alkaline liquor, a water phase and an oil phase, respectively, and a surfactant mixed liquor preparation kettle and a microemulsion reaction kettle. The biosurfactant microemulsion production system for cosmetics, food, chemical engineering and agriculture provided in the above technical scheme is capable of quickly producing the microemulsion of the biosurfactant by performing purification and microemulsion on the fermentation liquor.

Description

technical field [0001] The invention relates to the field of emulsifier production, in particular to a production system of biosurfactant microemulsion for cosmetics, food, chemical industry and agriculture. Background technique [0002] Microemulsions are transparent or translucent spontaneously formed thermodynamically stable systems, and there are two types: oil-in-water and water-in-oil. The formation of microemulsion is spontaneous and does not require external energy. It is a thermodynamically very stable system, so it is widely used in petrochemical, cosmetics, food and other fields. Among them, microemulsions prepared by biosurfactants are often used in high-end cosmetics, which are more stable, high in safety, and good in skin absorption. The preparation method of this type of microemulsion is: mix biosurfactant (lipopeptide biosurfactant), co-surfactant (C3-C5 alcohol) and alkali (sodium hydroxide) to prepare surfactant mixture , prepare the water phase (generall...

AI Technical Summary

Problems solved by technology

The preparation method of this type of microemulsion is: mix biosurfactant (lipopeptide biosurfactant), co-surfactant (C3-C5 alcohol) and alkali (sodium hydroxide) to prepare surfactant mixture , prepare the water phase (generally brine), prepare the oil phase (generally alkanes, cycloalkanes, aromatic hydrocarbons); add the prepared surfactant mixture into the water phase and mix evenly, then add the oil phase drop by drop to the above solution, and keep stirring evenly until the solution is from turbid to clear, that is, a microemulsion composed of biosurfactants is obtained. Since the oil phase needs to be used drop by drop, the production rate of the microemulsion is at the bottom, which seriously affects product production rate
