Embodiment 1

[0058] Embodiment 1, the comparison of the mosquito repellent time of compositions 1~2

[0059] 1. Source of components

[0060] The wheat protein used in the following examples is RUCIKAGOLDENELF from Shanghai Huihai Biotechnology Co., Ltd., which is wheat protein extracted from wheat grain endosperm, and the average molecular weight of protein fragments is 32000 Daltons.

[0061] The mosquito repellent used in the following examples is Imonin, purchased from Merck IR3535.

[0062] 2. Preparation of Composition 1 and Composition 2

[0063] Measure ethanol and Yimonin, add to deionized water, mix, so that the final concentrations of ethanol and Yimonin are respectively 45% (w / w) of ethanol and 6% (w / w) of Yimonin to obtain the combination Object 1.

[0064] Measure ethanol and Yimonin, add to deionized water, weigh wheat protein, mix, so that the final concentrations of ethanol, Yimonin, and wheat protein are respectively 45% (w / w) of ethanol and 6% of Yimonin. (w / w), 0.95...

Embodiment 2

[0080] Embodiment 2, the comparison of the mosquito repellent time of compositions 3-6

[0081] 1. Prepare compositions 3-6

[0082] Measure ethanol and Immonine, add to deionized water, mix, so that the final concentrations of ethanol and Immonine are respectively 48.56% of ethanol and 4.65% of Immonine to obtain composition 3.

[0083] Measure ethanol and Yimonin, weigh citric acid and sodium citrate, add them to deionized water, and mix well, so that the final concentrations of ethanol, Yimonin, citric acid, and sodium citrate are respectively 48.56% of ethanol and Yimonin. Ning 4.65%, citric acid 0.05% (w / w), sodium citrate 0.55% (w / w), the composition 4 was obtained.

[0084] Measure ethanol and Imonin, weigh wheat protein, citric acid, and sodium citrate, add them to deionized water, and mix well, so that the final concentrations of ethanol, Imonin, wheat protein, citric acid, and sodium citrate are respectively Composition 5 was obtained with 45% ethanol, 6% Immonin, ...

Embodiment 3

[0104] Embodiment 3, the preparation of aqueous solution

Abstract

The invention relates to a long-acting insect repellent composition, a preparation method and applications thereof, wherein the insect repellent composition uses ethanol, dimethyl phthalate and wheatprotein as main active components, and can substantially prolong the mosquito repellent time of the mosquito repellent product.

Description

technical field [0001] The invention belongs to the field of insect control, more specifically, the invention relates to a long-acting insect repellent composition, its preparation method and its application. Background technique [0002] Many vector insects can spread diseases, cause skin diseases or seriously harass humans, and then affect people's lives. The use of insect repellents is an important means of protection. The working principle of the repellent is roughly as follows: When the mosquito is identifying the receptor, the repellent can interfere or hinder the mosquito's tactile organs and chemoreceptors, making it change the flight route and away from the original target. [0003] Among the anti-mosquito repellents, DEET was once considered to be an ideal product because of its long use time and wide application range. However, in recent years, studies have successively found that it has some toxicological risks, such as possible allergy to children, and neurolog...
