| N,N-Diethyl-3-methylbenzamide Usage And Synthesis |
| Outline | N,N-Diethyl-3-methylbenzamide, with the chemical name diethyl toluamide, is a broad-spectrum insect repellent, having repellent effect upon a variety of biting insects in various environments , can be used to drive thorn flies, midges, black flies, chiggers, deer flies, fleas, gnats, horse flies, mosquitoes, sand flies, gnats, flies and stable flat lice. N,N-Diethyl-3-methylbenzamide is a development by the US Department of Agriculture during the World War II and has the patent, the product is designated as a repellent products for the use in the US Army in 1946. In 1957 the United States Environmental Protection Agency started civil application as an insect repellent registration, initially as a pesticide on the farm, and later the United States Government applied for its use in times of war, especially war in Vietnam and Southeast Asia, the United States Environmental Protection Agency statistics, every year nearly 40 percent of Americans use N,N-Diethyl-3-methylbenzamide -containing insect repellent, there are about 200 million people worldwide usage for over 40 years by more than 20,000 units of the research studies prove that N,N-Diethyl-3-methylbenzamide is the most secure and effective broad-spectrum repellent. World Health Organization has recommended the use of repellent products containing N,N-Diethyl-3-methylbenzamide to protect against insect vectors. Often mixed with other pesticides, but when it is mixed with an amino acid salts, pesticides toxicity will increase. |
| US Morflex one-step synthesis |
US Morflex founded in 1927, located in Greensboro, United States, is the world's largest manufacturer of N,N-Diethyl-3-methylbenzamide . It owns 40 years of production and sales of N,N-Diethyl-3-methylbenzamide history, providing 60 percent of global consumption. Users include Johnson, Bayer and other famous enterprises, Morflex repellent cream formulation has cosmetic properties, non-irritating to human skin, more even applied than alcohol formula , more comfortable, no dry and tight and not greasy sense after the use of alcohol formula, specially formulated to lock N,N-Diethyl-3-methylbenzamide in sweat, friction, etc., can maintain long-lasting efficacy. Its production methods can be called "one step synthesis" , the advantage of "one step synthesis" is that it does not produce chemical synthesis additions - phosphoric acid, hydrochloric acid, amine hydrochloride or benzene. Phosphoric acid can cause greasy products, and other impurities are either irritating to the skin, or harmful to the human body. The multi-step synthesis methods currently used in the country can not avoid these harmful chemicals addenda. The above information is edited by the Chemicalbook of Tian Ye. |
| Insect repellent effects of various products |
The product containing chemical drug N,N-Diethyl-3-methylbenzamide owns best effects. Preferably, the time it can provide protection is proportional to the concentration of N,N-Diethyl-3-methylbenzamide products. For using products with N,N-Diethyl-3-methylbenzamide concentration at 23.8%, 20%, 6.6% and 4.8% , the protection times of the participants for the first time the average time being bitten are 302 minutes, 234 minutes, 112 minutes, 88 minutes, respectively . The average time of plant protection products as follows: 2% soybean oil products for 95 minutes; citronella oil product containing different concentrations of 3 to 20 minutes; the average protection time containing eucalyptus oil repellent latest listing of 120 minute. Many consumers believe that there is repellent function of the "Skin Bath Oil", provide protection only 10 minutes. Products contains a chemical component (Merck insecticide product IR3535) , the average protection time is only 23 minutes. |
| Pregnant women should us N,N-Diethyl-3-methylbenzamide insect repellents with caution | N,N-Diethyl-3-methylbenzamide has potential risks to humans, especially pregnant women: after contacted with the skin, N,N-Diethyl-3-methylbenzamide -containing insect repellent products will penetrate into the blood, it is possible through the blood into the placenta, even umbilical cord, which may result in teratogenic. Pregnant women should avoid using N,N-Diethyl-3-methylbenzamide containing insect repellent products, pregnant women can choose to wear light-colored long-sleeved shirt and trousers, or using products containing natural ingredients repellent to prevent mosquito bites. If necessary, using insect repellent containing N,N-Diethyl-3-methylbenzamide products should also be with the lowest concentration and effective insect repellent components as possible. |
