What is Insect Repellent Deet?
Dissolving DEET in ethanol, although it has better anti-mosquito and bactericidal functions, but because ethanol has considerable degreasing and volatility, it will dissolve the normal keratin of the skin and lose water on the skin surface. In addition, the mosquito-repellent solution can also be made into an oil formulation for application to prevent mosquitoes. For example, the publication number CN1391800A discloses the use of zinc stearate, magnesium stearate, glycerin, polyethylene glycol and water to make a mosquito-repellent method .
DEET was developed by the United States in 1956 and is widely used worldwide because of its broad-spectrum insect repellent effect and good repellent effect. However, DEET crude oil generally has shortcomings such as greasy, burning and bad smell when applied to the skin, and even allergic reactions such as rashes and peeling. Therefore, it needs to be processed into different application states (formulations) for safe use.
Insect Repellent Deet Use
- The PTFE surface treatment film can be resistant to Deet penetration, can maintain a long-lasting waterproof effect, enhance the function of clothing, and make it more durable and more widely applicable.
- Deet has excellent mosquito repellent performance and can endow PVC with excellent mosquito repellent performance. The cobalt ions in cobalt stearate can react with the amine groups in cyclohexylamine and Insect Repellent Deet to form stable compounds and reduce It reduces the volatilization of cyclohexylamine and Insect Repellent Deet, and can improve the compatibility and dispersibility of cobalt stearate in PVC.
- Cyclohexylamine and Deet can also absorb the hydrogen chloride gas generated during the use of PVC, solve the environmental pollution problem caused by hydrogen chloride, and can reduce the corrosion of hydrogen chloride on the processing mold and increase the service life of the mold.

Use of DEET and Precautions
DEET has high overall safety and low toxicity. Existing studies believe that DEET has no carcinogenic, teratogenic and developmental effects. The US Centers for Disease Control and Prevention (CDC) recommends that pregnant and breastfeeding women use DEET (equivalent to non-pregnant adults) to avoid mosquito bites and reduce the risk of infectious diseases. At the same time, the American Academy of Pediatrics (AAP) recommends that infants over 2 months of age use 10%-30% DEET, which is safe and effective. It is not suitable for infants under 2 months of age.
The content of DEET on the market is between 5% and 99%, and studies have found that the content of 10% to 30% has similar effects in repelling mosquitoes. However, different concentrations of DEET have different effective times. 10% provide about 2 hours of protection time, and 24% provide up to 5 hours of protection time. In addition, swimming, sweating, wiping and raining can shorten the protection time of DEET. In this case, a higher concentration of DEET can be selected.
It should be noted that more than 30% DEET does not significantly increase the protection time. On the contrary, skin and mucous membrane irritation such as rashes and blisters may occur, and it may also have potential neurotoxicity.
DEET should be applied to exposed skin and clothing. In order not to spray into the eyes, it is recommended to apply it to the palm of the hand first, rub it with your hands and then apply a thin layer to the face. Wash hands after use to prevent accidental ingestion and eye contact. If you accidentally spray into your eyes, rinse slowly with clean water for 5-10 minutes. If you wear contact lenses, you need to wash them for 5 minutes and take them out immediately.
It is not necessary to use DEET frequently every day. It is recommended that infants and young children over 2 months do not use it more than once a day.
DEET should not be used on wounds or damaged skin (such as eczema). It is not suitable to be used in a confined environment because of the risk of inhalation from the respiratory tract. It must be kept away from open flames, smoking and high-temperature heat sources.
If you use sunscreen and DEET at the same time, you should use sunscreen first, then DEET, and you should not use a mixture of the two, which will increase the risk of exposure to excessive DEET. When DEET is no longer needed, wash the coated skin with soap and water.
Since DEET is also a plasticizer, it may damage mosquito nets, synthetic fibers, leather, plastic glasses frames and watches to a certain extent, but does not damage natural fibers such as cotton and wool. Daily need to properly protect related products.
