DEET:
DEET is a widely used insecticide, which can neutralize the tannic acid injected into the human body after mosquito bites, which is slightly irritating to the skin, so it is best to spray it on clothing to avoid direct contact with the skin. And this ingredient may damage nerves when used in large quantities. Frequent use of DEET may cause toxic reactions, so be sure to pay attention to the frequency and concentration when using it, and try to avoid long-term drinking and repeated use.
The working principle of DEET is to form a vaporous barrier around the skin by volatilization, which can interfere with the induction of volatiles on the human body by the chemical sensors of the mosquito antennae, thereby causing discomfort to mosquitoes and making people avoid mosquito bites.
Mosquito repellent:
Mosquito repellent, also known as ethyl butyl acetylaminopropionate, IR3535, and Yimening, is a plasticizer and a broad-spectrum, high-efficiency and low-toxic insect repellent. The chemical properties of repellent ester are stable and can be used in different climatic conditions. At the same time, it has high thermal stability and high sweat resistance. Mosquitoes are relatively weak.
The principle of mosquito repellent repellent is that mosquitoes use the olfactory system to find the target with the smell emitted by the human body, such as exhaled gas and the smell of the skin, and the role of mosquito repellent is in the human body. The surface forms a barrier, thereby isolating the emission of human body odor, paralyzing the olfactory system of mosquitoes, and interfering with the induction of odor by mosquitoes, thereby achieving the effect of repelling mosquitoes.
