Problems solved by technology

DEET, mosquito repellent, icaridin (Icaridine) and menthol are all mosquito repellent ingredients certified by the US Centers for Disease Control and Prevention (CDC) and the US Environmental Protection Agency (EPA), among which icaridin and menthol have shown higher safety and repellent activity, but most of the repellents on the market are single agents, and the duration of effect is not very long. Therefore, it is necessary to develop a long-acting, compound mosquito repellent agent becomes the main purpose of the present invention

Embodiment 1

[0018] Embodiment 1: the synthesis of active ingredient Menthadiol

[0019] Weigh 3.5g of lemon eucalyptus essential oil into a 100mL round bottom flask, then add 6.5mmol oxalic acid and 30mL water, react at 50°C, monitor the reaction by gas chromatography, stop the reaction after 72h, and cool to room temperature. After extraction with ethyl acetate, the organic phase was washed with saturated aqueous sodium bicarbonate solution and saturated brine respectively, dried over anhydrous sodium sulfate, and the solvent was spin-dried to obtain the parent drug of menthadiol.

[0020] Of course, the method for obtaining menthadiol is not limited to this method, and it can also be obtained by other methods, and can also be a commercially available menthadiol product.

Embodiment 2

[0021] Example 2: 10% Menthadiol Mosquito Repellent Liquid

[0022] Take 10g of menthadiol, 20.0g of double decohol, add water to make up to 100.0g, and mix well.

Embodiment 3

[0023] Example 3: 10% Icaridin Mosquito Repellent Liquid

[0024] Take 10.0g of icaridin, 20.0g of double-dealcohol, add water to make up to 100.0g, and mix well.

Abstract

The invention discloses efficient compound mosquito repellent liquid, which is prepared from active ingredients of piperitenol and icaridin, wherein the piperitenol is obtained by using naturally extracted eucingyptus essential oil as raw materials under the acid catalysis effect. The efficient compound mosquito repellent liquid has the advantages that through the mutual mixing and proportioning of the piperitenol and the icaridin; the mutual conflict cannot occur; after the compounding of the piperitenol and the icaridin, the compound ingredients have longer effective mosquito repellent timethan the single piperitenol or the icaridin; the synergistic interaction can be realized.

Description

technical field [0001] The invention relates to a mosquito repellent product, in particular to a mosquito repellent composition compounded with menthol and icaridin. Background technique [0002] Mosquitoes have become a serious public health problem in various countries. According to the survey of WHO (World Health Organization), mosquitoes are the animal that kills the most human beings, up to 725,000 people every year. In 2015, the number of deaths due to mosquitoes climbed to 830,000. Mosquitoes are the vector of infectious diseases, especially in tropical areas, many infectious diseases are often transmitted to humans through mosquitoes, seriously endangering human health. At present, the prevention and control means of mosquito harm mainly adopt chemical insecticides and mosquito repellents. However, the extensive use of pesticides is likely to cause problems such as drug resistance and environmental pollution. And repellent is not to kill mosquitoes directly, main...
