Problems solved by technology

[0003] However, the slow release of natural flavors can be achieved through microcapsule technology, and the use of oil-soluble antibacterial natural flavors can achieve certain antibacterial and bactericidal functions, but the microcapsule material itself as a carrier of flavors cannot be antibacterial and bactericidal, so the inhibition of natural antibacterial flavors Bacteria, bactericidal performance will be greatly reduced, can not be well played
In addition, in the existing production technology of essence microcapsules, a large amount of surfactant needs to be added, which not only increases the processing cost of essence microcapsules, but also may cause adverse effects such as skin allergies to users, which will hinder the production of essence microcapsules. to promote

[0029] see figure 1 , the preparation method of self-emulsifying internal and external double-effect antibacterial essence microcapsules of one embodiment comprises the following steps:

[0030] S110: dissolving the chitosan quaternary ammonium salt in water to obtain an aqueous chitosan quaternary ammonium salt solution.

[0031] By dissolving the chitosan quaternary ammonium salt in water, an aqueous chitosan quaternary ammonium salt solution can be obtained based on the water solubility of the chitosan quaternary ammonium salt itself.

[0032] S120: adding the oil-soluble antibacterial natural essence into the chitosan quaternary ammonium salt solution, and performing an emulsification operation to obtain a first emulsion.

[0033] Because the chitosan quaternary ammonium salt is a good emulsifier, when the oil-soluble antibacterial natural essence was added to the chitosan quaternary ammonium salt, the oil-soluble antibacterial natural essence was used as the oil phase co...

Abstract

The invention discloses a preparation method of a self-emulsifying internal and external double-effect antibacterial essence microcapsule. The preparation method comprises the following steps: respectively preparing a chitosan quaternary ammonium salt aqueous solution and a sodium polyacrylate aqueous solution, respectively adding oil-soluble antibacterial natural essence into the chitosan quaternary ammonium salt aqueous solution and the sodium polyacrylate aqueous solution, obtaining a first emulsion and a second emulsion, mixing the first emulsion with the second emulsion, adding a crosslinking agent, and obtaining the self-emulsifying internal and external double-effect antibacterial essence microcapsule. According to the preparation method of the self-emulsifying internal and externaldouble-effect antibacterial essence microcapsule, by optimizing a formulation of a capsule wall, the capsule wall of the essence microcapsule is prepared without adding an additional surfactant, so that the production cost of the essence microcapsule is reduced, the capsule wall and the capsule core of the essence microcapsule are endowed with an antibacterial function, and the antibacterial properties of the essence microcapsule are enhanced; moreover, a skin allergic phenomenon of a user is effectively reduced because no additional small molecule surfactant is added.

Description

technical field [0001] The invention relates to an essence microcapsule, in particular to a self-emulsifying, internally and externally double-effect antibacterial essence microcapsule and a preparation method thereof. Background technique [0002] Along with improving day by day of people's living standard, the addition of fragrance of various articles for use in daily life has become more and more commonplace phenomenon. Since most of the essences have a fast volatilization speed, long-term fragrance addition is particularly important. Microencapsulation technology is a good way to solve long-term fragrance addition. The essence is encapsulated in microcapsules, and through a certain release mechanism Slowly release the aroma to achieve long-lasting fragrance effect. Many flavors, especially natural flavors, also have a good bactericidal function. Combining flavoring with antibacterial and bactericidal functions is very important in public places such as medical care, kin...
