Abstract

The invention provides a micro-emulsified culicifuge and a preparation method thereof. The culicifuge comprises phthalthrin, allethrin, piperonyl butoxide, salicylic acid, ethyl acetate, peroxyacetic acid, dimethyl phthalate, citronellal, citronella oil, cassia oil, litsea cubeba oil, pine oil, pine needle oil, vetiver oil, ethanol, an emulsifier, a co-emulsifier, an antifreezing agent, an antifoaming agent, and water. The preparation method comprises: adding phthalthrin, allethrin, piperonyl butoxide, salicylic acid, ethyl acetate, peroxyacetic acid, dimethyl phthalate, the antifreezing agent, and the antifoaming agent into water for uniform stirring to obtain a mixed solution I; mixing the left components for uniform stirring to obtain a mixed solution II; and adding the mixed solution I to the mixed solution II while performing stirring to obtain the micro-emulsified culicifuge. The micro-emulsified culicifuge is good in mosquito-repelling effect, long in lasting time, and low in toxicity, is suitable for family use, and particularly suitable for pregnant women and children.

Description

technical field [0001] The invention belongs to the technical field of daily chemical products, and in particular relates to a microemulsion mosquito repellent and a preparation method thereof. Background technique [0002] Mosquitoes are one of the four pests and are carriers of viruses. With the development of society and the continuous improvement of human living standards, people's awareness of health and self-protection is also increasing, and various mosquito repellent products have emerged one after another. At present, there are many mosquito repellent products on the market, mainly concentrated in disc mosquito coils, mosquito coils, aerosol mosquito killers, toilet water, mosquito repellent cream, mosquito repellent spirit, heated mosquito coils, etc. Most of these mosquito repellent products rely on pesticides or chemical ingredients to achieve the mosquito repellent effect, and only a few use natural non-toxic and harmless ingredients to achieve the mosquito rep...
