Embodiment 1

[0028] A plant-derived mosquito repellent, comprising 0.5% hydrogel (selecting gellan gum), 5.0% slow-release agent (selecting hydrogenated castor oil peg60), 5.0% surfactant (selecting Tween-80), and 5.0% ethanol %, Pork Plum Oil Extract, Deionized Water. Among them, the gradients of 2.5%, 5.0%, 10.0%, 15.0%, 20.0%, 25.0%, and 30.0% of the oil extract of Prunus japonicus were selected, and the rest was made of deionized water to make a plant-source mosquito repellent, and the plant-source The mosquito repellent was tested on the mosquito repellent effect on the first day, and the test results are shown in Table 1 below:

[0029] Table 1. The effect of different contents of Baiqiu plum oil extract on the mosquito repellent effect

[0030]

[0031]

[0032] It can be seen from the above table that with the increase of the proportion of plant essential oils in the plant-derived mosquito repellent, the mosquito repellent effect first increases and then remains stable, and ...

Embodiment 2

[0034] A plant-derived mosquito repellent, comprising 0.5% hydrogel (selecting gellan gum), 5.0% slow-release agent (selecting hydrogenated castor oil peg60), 5.0% surfactant (selecting Tween-80), and 5.0% ethanol %, 10.0% plant essential oil (mixture of Prunus plum oil extract and Nepeta oil extract), deionized water 74.5%.

[0035] Among them, taking 10.0% plant essential oil in the plant-source mosquito repellent, and the plant essential oil contains 5-90 parts of pomegranate oil extract, and 10-95 parts of nepeta oil extract as an example to prepare plant-source mosquito repellent repellant. Plant essential oils are formed by combining different numbers of Prunus japonica oil extracts and Nepeta oil extracts, and then made into a plant-derived mosquito repellent, and the mosquito repellent effect of the plant-derived mosquito repellent is tested, and the above test is carried out Result is compared with the first day mosquito repellent effect of the plant source mosquito re...

Embodiment 3

[0041] A plant-derived mosquito repellent, comprising 0.5% hydrogel (selecting gellan gum), 5.0% slow-release agent (selecting hydrogenated castor oil peg60), 5.0% surfactant (selecting Tween-80), and 5.0% ethanol %, 10.0% plant essential oil, 74.5% deionized water.

[0042] Among them, 10.0% of plant essential oils in the plant-derived mosquito repellent, plant essential oils include lotus plum oil extract, nepeta oil extract, litsea cubeba oil extract, clove flower oil extract, thyme oil extract, There are 6 kinds of essential oils in total of laurel oil extracts, and the plant essential oils contain 5-10 parts of Pork Plum Oil Extract, 10-40 parts of Nepeta Oil Extract, 10-25 parts of Litsea Cubeba Oil Extract, Lilac Flower 5-25 parts of oil extract, 5-15 parts of thyme oil extract, and 5-10 parts of laurel oil extract, wherein the sum of the parts of each component is 100 parts as an example to prepare plant-source mosquito repellent agent. The plant source mosquito repe...

Abstract

The invention provides a botanical mosquito repellent, which comprises plant essential oil, hydrogel, a surfactant, a slow release agent, ethanol and deionized water, and the plant essential oil comprises a pachouli oil extract. The invention also provides a preparation method of the botanical mosquito repellent, which comprises the following steps of: adding ethanol into the plant essential oil,stirring uniformly, adding the surfactant and the slow release agent, and stirring uniformly to obtain a mixed solution A; adding deionized water and hydrogel into a container, and heating and stirring to obtain mixed colloid B; and cooling the mixed colloid B to 40-50 DEG C, slowly adding the mixed solution A into the mixed colloid B, and stirring until the mixed solution A and the mixed colloidB are uniformly mixed to obtain the botanical mosquito repellent. The botanical mosquito repellent can overcome the harm of a chemically synthesized mosquito repellent to human beings and the environment, and can be slowly released in the use process, so that the mosquito repellent time is prolonged, and the mosquito repellent effect is improved.

Description

technical field [0001] The invention belongs to the field of sanitary pest prevention and control, and relates to mosquito repellent product technology, in particular to a plant-derived mosquito repellent and a preparation method thereof. Background technique [0002] Mosquitoes are an important class of vector insects. They not only suck human blood, but also carry a variety of pathogenic microorganisms in their bodies, which seriously endanger human safety and health. In the struggle against mosquitoes, people have adopted many methods, for example, insecticides, which are synthesized by chemical methods, are used to kill mosquitoes and have good control effects on mosquitoes in relatively closed spaces, but long-term The use of chemically synthesized insecticides has caused problems such as 3R and the environment; repellents include chemically synthesized and natural ones, which themselves have no insecticidal effect, and can achieve the purpose of repelling mosquitoes by...
