  • Uses 1. As major components for a variety of solid, liquid mosquito repellent series. 2. Insect repellent, having unique effects for mosquito controlling . Formulation: 70%, 95% liquid. DEET is an Insect repellent.This compound is a contaminant of emerging concern (CECs). Insect repellent DEET is used as an insect repellent.
  • production method By the Inter-toluene chloride and diethyl amine reaction. Industrial products containing 5%-15% isomer.
  • Description DEET was first developed and patented by the US Army in 1946. It was approved for general public use by the US Environmental Protection Agency (EPA) in 1957 and was reregistered in 1998. It has been estimated that more than 1.8 million kg (~4 million pounds) of DEET are used in the United States every year in more than 225 registered products. DEET is often sold and used in lotions or sprays with concentrations up to 100%. However, the Center for Disease Control recommends only 30–50% DEET to reduce the incidence of vector-borne disease transmission. Registered products must contain at least 95% of the meta-isomer, but small amounts of the more toxic ortho-isomer and the less toxic para-isomer are permitted.
  • Indications DEET is an organic liquid that is an excellent mosquito repellent; stronger preparations of DEET are also effective against stable flies, although little protection is provided against ticks. Commercial preparations are available in aerosol, cream, or lotion form and vary in concentration from 6% to 100%. Because DEET is absorbed into the bloodstream, it should be applied sparingly. Lesser concentrations of DEET should be used whenever possible, with additional applications to the skin if needed. Reports of a toxic encephalopathy and brief seizures have been documented in children after overzealous use. Less serious neurologic side effects include confusion, irritability, and insomnia. Contact dermatitis has been observed with preparations containing higher concentrations of DEET. Use preparations with <20% DEET in children. Avoid mucous membranes, broken skin, and hands of children, because they are often in contact with the mouth. Spray clothing instead of skin whenever possible, but avoid contact with rayon, acetate, or spandex, because these materials may be damaged by DEET.
