Diethyl-m-toluamide, commonly known as DEET, is a widely used insect repellent that was first developed by the U.S. Department of Agriculture in 1946. It is effective against a broad range of insects, including mosquitoes, ticks, and other biting pests. DEET works by interfering with the insects' ability to detect the chemicals that attract them to humans, such as lactic acid and 1-octen-3-ol, which are present in human sweat and breath.
DEET is available in various formulations, such as liquids, lotions, sprays, and impregnated materials like towelettes or roll-ons. It is typically applied directly to the skin or to clothing and provides protection for several hours. The duration of protection is proportional to the concentration of DEET used, with higher concentrations offering longer-lasting protection. However, there is a plateau effect at concentrations around 50%, where additional increases do not significantly prolong the duration of protection.
The chemical formula for DEET is C12H17NO, and it has a molecular weight of 191.27. It is a colorless to with a mild, non-irritating odor. DEET has a melting point of -45 °C and a boiling point of 288-292 °C. It is poorly soluble in water but readily dissolves in organic solvents such as ethanol, acetone, and xylene.
