Problems solved by technology

[0005] 1) Since the chemical composition of this type of product is unevenly distributed, it must be fully shaken before use;
[0006] 2) Part of the sprayed medicine liquid is emulsion, which affects the use effect of the product;
[0007] 3) After the thick milky canned medicinal liquid goes through the process of filling the propellant, the high-pressure and fast-filling propellant will simulate the secondary stirring of the emulsion, causing some products to break and affect the stability of the product;

Abstract

The invention provides a microemulsion oil-in-water insect aerosol, comprising the following components by weight percent: 0.25-0.55 percent of Es-bioallethrin, 0.2-0.35 percent of permethrin, 0.15-0.3 percent of kerosene, 3.5-5.2 percent of surface active agent, 0.1-0.3 percent of weakly alkaline preservative, 50-56 percent of deionized water and 38-45 percent of dimethyl ether. The microemulsion oil-in-water insect aerosol has the characteristics of high efficiency, low toxicity, safe use, no pungent smell, no environmental pollution, no trace leaving after use, and the like.

Description

technical field [0001] The invention relates to an insecticidal aerosol, in particular to a microemulsion oil-in-water type insecticidal aerosol. Background technique [0002] The insecticidal aerosols produced in my country rank among the top in the world in terms of the number of varieties and the output, but a considerable part of the insecticidal aerosol products are similar and belong to low-level redundant construction. The good news is that in recent years, some companies have researched and developed insecticidal aerosol products with their own characteristics, such as water-based insecticidal aerosols, odorless aerosols and bactericidal insecticidal aerosols. The rapid emergence of content products is a good proof. [0003] The development of insecticidal aerosol products adapts to the socio-economic level and consumer demand, and its varieties also change in different stages of social development. In fact, the output, structure, and function of insecticide aeroso...
