How does DEET work?

How does DEET work?

DEET works to confuse and interfere with the receptors on a mosquito’s antennae, which deters mosquitoes from landing on the skin and biting. These receptors are used to detect body heat, carbon dioxide and skin chemicals when seeking out prey.

What is the chemical makeup of DEET?

4.1 CHEMICAL IDENTITY DEET is the chemical, N,N-diethyl-meta-toluamide, ortho and para isomers are present at low concentrations. DEET is an N,N-disubstituted aromatic carbonamide, which is used as an active ingredient in insect repellents. DEET was registered for commercial use by the general public in 1957.

What is DEET reaction?

People that have left DEET products on their skin for extended periods of time have experienced irritation, redness, a rash, and swelling. People that have swallowed products containing DEET have experienced stomach upset, vomiting, and nausea. Very rarely, exposure to DEET has been associated with seizures in people.

How does N N diethyl meta toluamide work?

DEET is designed for direct application to people’s skin to repel insects. Rather than killing them, DEET works by making it hard for these biting bugs to smell us. After it was developed by the U.S. Army in 1946, DEET was registered for use by the general public in 1957.

What is DEET soluble in?

N,N-diethyl-meta-toluamide (DEET) (C12 H17 NO) is one of the best insect repellents has been used for many years. DEET is a colorless, odorless liquid that is approximately insoluble in water and soluble in glycerin, ethanol, and isopropyl alcohol.

Why does DEET melt plastic?

As demonstrated with a plastic cup, DEET can melt plastic because it is a member of the tolune chemical categories, and these chemicals are solvents meaning they melt things, basically.
