Abstract

The present invention relates to an ethyl lauroyl arginate hydrochloride microcapsule and preparation technology thereof. The preparation technology is prepared by: using ethyl lauroyl arginate hydrochloride as core materials; using starch sodium octenyl succinate and cyclodextrin as wall materials, proportionally mixing the wall materials with anticaking agents, dispersants and aqueous phase antioxidants, and homogenizing and spray drying the mixture to obtain ethyl lauroyl arginate hydrochloride microcapsule powder. There is no need to add any organic solvents in the preparation process of the ethyl lauroyl arginate hydrochloride microcapsule, and the function activity of obtained products can be kept; and the ethyl lauroyl arginate hydrochloride microcapsule is characterized by increased solubility at low temperature and greatly improved usability and water solubility. The ethyl lauroyl arginate hydrochloride microcapsule is more conducive to processing, transportation and storage, and is excellent antiseptic materials. The ethyl lauroyl arginate hydrochloride microcapsule produced by the preparation technology is high in yield, and suitable for large-scale preparation to realize the continuous and large-scale production.

Description

technical field [0001] The invention relates to the technical field of production of ethyl lauroyl arginine hydrochloride microcapsules, in particular to a preparation process of ethyl lauroyl arginine hydrochloride microcapsules. Background technique [0002] Lauroyl arginine ethyl ester hydrochloride is a new type of antibacterial agent. The antibacterial properties of lauroyl arginine ethyl ester hydrochloride can reduce the surface tension of microbial cells and the formation of ion polymerization, so that the conductivity of microbial cell membranes and solubility changes, thereby disrupting cell membrane proteins. Disruption of membrane proteins results in the leakage of ions and other cellular components, altering the permeability of the microbial cell, which can inhibit the growth of the microbe, or inactivate it. According to research, ethyl lauroyl arginate hydrochloride has a strong antibacterial effect on Gram-negative and Gram-positive bacteria, yeast and mold....
