Is DEET soluble in water?
Aromatic amides have insect repellent effects. N,N-diethyl-meta-toluamide (DEET) (C12 H17 NO) is one of the best insect repellents has been used for many years. DEET is a colorless, odorless liquid that is approximately insoluble in water and soluble in glycerin, ethanol, and isopropyl alcohol.
Is Diethyltoluamide the same as DEET?
N,N-Diethyl-meta-toluamide, also called DEET (/diːt/) or diethyltoluamide, is the most common active ingredient in insect repellents. It is a slightly yellow oil intended to be applied to the skin or to clothing and provides protection against mosquitoes, flies, ticks, fleas, chiggers, leeches and many biting insects.
What is the structure of DEET?
C12H17NODEET / Formula
How does DEET work chemistry?
DEET works to confuse and interfere with the receptors on a mosquito’s antennae, which deters mosquitoes from landing on the skin and biting. These receptors are used to detect body heat, carbon dioxide and skin chemicals when seeking out prey.
Is DEET a plasticizer?
DEET is a plasticizer and can damage certain rubber, plastic, vinyl, or elastic materials such as contact lenses, eyeglass frames and lenses, watch crystals, combs, painted and varnished surfaces, and certain synthetic or treated fabrics. DEET does not damage natural fibers including cotton and wool.
Does DEET evaporate?
DEET is usually applied to the skin, but the active ingredient must evaporate from the surface to work, the repellent activity lasts for a limited time, depending upon the concentration used.
Is Diethyltoluamide safe?
The human health risk assessment concluded that there are no risks of concern because no toxic effects have been identified when used as a dermally applied insect repellent, and there is no dietary or occupational exposure for DEET.
Is Diethyltoluamide toxic?
DEET generally is of low acute toxicity, and, based on the available toxicological data, the Agency believes that the normal use of DEET does not present a health concern to the general U.S. population (the Agency’s human risk assessment has identified no toxicologically significant effects in animal studies.)
What is the density of DEET?
998 kg/m³DEET / Density
What is the problem with DEET?
People that have left DEET products on their skin for extended periods of time have experienced irritation, redness, a rash, and swelling. People that have swallowed products containing DEET have experienced stomach upset, vomiting, and nausea. Very rarely, exposure to DEET has been associated with seizures in people.
Why does DEET melt plastic?
As demonstrated with a plastic cup, DEET can melt plastic because it is a member of the tolune chemical categories, and these chemicals are solvents meaning they melt things, basically.
How long does DEET last surfaces?
Air. DEET will exist as a vapor in ambient air and degrade via hydroxyl- radicals with an estimated half-life of 15 hours.
Does DEET expire?
DEET—a chemical featured in many popular insect repellent brands—is an effective and highly stable ingredient that, like oil-based products, doesn’t expire.
How long does bug spray stay in the air?
The odor of Raid stays in the air for 15-20 minutes, when the room is ventilated. The ventilation is key to letting the Raid chemicals out!
Is Diethyltoluamide safe for dogs?

Does DEET dissolve nylon?
DEET dissolves nylon and waterproof/breathable fabrics.
How does diethyltoluamide work?
Most diethyltoluamide (DEET) formulations employ the agent as a liquid to be applied onto human skin in an effort to repel mosquitoes from feeding on the skin. Topical application and absorption is consequently the most common route of absorption.
What is the toxicity of NDN-diethyl-m-toluamide?
N,N-diethyl-m-toluamide (CAS # 134-62-3) was evaluated for acute oral toxicity. The test substance was administered to male albino Charles River CD rats. Dosages and mortality data are as follows: 0.4 g/kg (0/3); 0.8 g/kg (0/3); 1.6 g/kg (0/3); 3.2 g/kg (1/3); 5.0 g/kg (3/3).
What are the properties of N-N-diethyl-m-toluamide?
This chemical is sensitive to prolonged exposure to moisture. Insoluble in water. N,N-DIETHYL-M-TOLUAMIDE is incompatible with strong acids, strong bases and strong oxidizing agents. It hydrolyzes slowly in the presence of water. It has a solvent effect on most plastics, paints, and varnishes.
What does ND-diethyl-m-toluamide look like?
N,n-diethyl-m-toluamide appears as clear colorless or faintly yellow slightly viscous liquid. Faint pleasant odor. (NTP, 1992)
