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.

Application:
N,N-Diethyl-m-toluamide (DEET), with CAS number 134-62-3, is a versatile chemical widely utilized across various applications due to its effectiveness as an insect repellent. Here are some key applications of DEET as a raw material:
1. Personal Insect Repellents: DEET is a primary ingredient in numerous consumer insect repellent products. These include sprays, lotions, gels, and wipes designed for direct application to the skin and clothing. These products are used to protect individuals from insect bites, particularly in areas where insects are a health concern or during outdoor activities.
2. Outdoor Gear and Clothing Treatment: DEET is used to treat outdoor gear and clothing, such as tents, sleeping bags, and hiking apparel. This application helps provide a barrier against insects and enhances the effectiveness of insect repellent strategies during camping or other outdoor adventures.
3. Military and Occupational Use: DEET is extensively used by military personnel and workers in professions such as forestry, agriculture, and construction, where exposure to biting insects is common. It helps in maintaining operational efficiency and preventing insect-borne diseases in high-risk environments.
4. Public Health Initiatives: DEET-based repellents are often included in public health campaigns aimed at controlling vector-borne diseases. In regions where insect-borne diseases are prevalent, DEET products are distributed as part of disease prevention strategies to protect communities and reduce the spread of illnesses.
5. Household and Industrial Applications: DEET is also utilized in certain household and industrial products designed to deter insects from specific areas. This includes products like insect repellent candles and mats that are used to create insect-free zones in indoor and outdoor spaces.
