Problems solved by technology

[0005] The researchers of the present invention have found through a large number of studies that individual plant essential oils often have a "fence effect" as an antibacterial agent, that is, they may have a strong antibacterial effect on a certain species of microorganisms, but may have a strong antibacterial effect on another certain species of microorganisms. There is no better antibacterial effect; on the other hand, even through compound technology, compound plant essential oils often produce an antibacterial effect of 1+1 less than 2
In short, natural plant essential oil antibacterial agents still have relatively large limitations, mainly due to limited antibacterial ability, low bactericidal rate, and no broad-spectrum long-term effect.

Abstract

The invention discloses a compound antimicrobial composition containing microcapsules and a preparation method and application of the compound antimicrobial composition. The method includes the steps of firstly, homogenizing and evenly mixing folium artemisiae argyi essential oil, pogostemon cablin essential oil, fennel fruit essential oil and emulgator to obtain emulsified liquid I; secondly, dissolving tremella heteropolysaccharide and pectin in water, adding the emulsified liquid I to the mixture at the temperature of 45-50 DEG C, and evenly mixing the mixture to obtain emulsified liquid II; thirdly, dissolving polyamino acid in water, and dropwise adding the emulsified liquid II at the temperature of 65-75 DEG C in the stirring state; fourthly, continuing to conduct heat preservation and heating after the emulsified liquid II is dropwise added; fifthly, lowering the temperature to 40-45 DEG C, adding polyhydric alcohol, stabilizer and bispyrithione dispersion liquid, and conducting even stirring to obtain the compound antimicrobial composition containing microcapsules. The compound antimicrobial composition has the advantages of having the broad-spectrum antibacterial capacity and being high in antibacterial property and stability, and the like, and the market application potential is large.

Description

technical field [0001] The invention relates to the technical field of daily chemicals, in particular to a composite antibacterial composition containing microcapsules, a preparation method and application thereof. Background technique [0002] Antibacterial agents (Anti-bacterial agents) refer to substances or products that can keep the growth or reproduction of certain microorganisms (bacteria, fungi, yeast, algae, viruses, etc.) below the necessary level within a certain period of time. Antibacterial agents are generally divided into inorganic antibacterial agents, organic antibacterial agents and natural antibacterial agents. [0003] In the field of daily chemicals, the antibacterial agents used are mainly organic antibacterial agents, the main varieties are anilides, imidazoles, thiazoles, isothiazolone derivatives, quaternary ammonium salts, biguanides, phenols, etc. However, these antimicrobials are often toxic, harmful or risky substances. Especially in products t...
