Mosquito Repellent N,N-Diethyl-m-toluamide Deet CAS 134-62-3



N,N-Diethyl-m-toluamide (DEET) is a widely used broad-spectrum insect repellent. The following sections provide an overview of DEET from five perspectives: basic information, mechanism of action, application areas, safety and regulation, and market status:


Basic Information


Chemical Name: N,N-Diethyl-m-toluamide (or N,N-Diethyl-3-methylbenzamide).

CAS Number: 134-62-3.

Molecular Formula: C₁₂H₁₇NO.

Molecular Weight: 191.27.

Physical Properties: Typically a pale yellow to amber-colored transparent liquid, insoluble in water, but soluble in organic solvents such as ethanol and acetone.


Mode of Action


DEET interferes with insect olfactory receptors, blocking their perception of chemical signals such as human sweat and exhaled gases, thereby reducing insects' desire to attack humans. Its efficacy has been validated by numerous experiments and demonstrates significant repellent effects against various biting insects including mosquitoes, ticks, fleas, mites, and horseflies.

DEET Application:


1. Personal protection:

* As the core ingredient in mosquito repellent lotions, perfumes, and soaps, it can be applied directly to the skin or clothing to provide protection for several hours to several days.

* Suitable for outdoor activities, travel, military operations, and other scenarios, it effectively prevents diseases transmitted by mosquito bites (such as malaria, dengue fever, and Zika virus).


2. Industrial and Agricultural Applications:

*Used in the formulation of aerosol-based lotions and creams for mosquito repellent products to meet specific industry requirements.

*In the agricultural sector, it can be used as an adjuvant in combination with other pesticides to enhance insect repellent efficacy (however, caution is advised against mixing with carbamate pesticides to prevent increased toxicity).



DEET Advantage:


The core advantage of N,N-Diethyl-m-toluamide (DEET) lies in its highly effective repellency against various disease-carrying insects, providing reliable protection to reduce the risk of infection from vector-borne diseases, and demonstrating high safety when used as directed. The following is a detailed explanation of its advantages:


1. Highly effective at repelling a wide range of disease-carrying insects

DEET is one of the few compounds capable of repelling multiple types of biting insects, including mosquitoes, ticks, fleas, mites, and horseflies. Its mechanism of action involves interfering with the insects' olfactory receptors, blocking their perception of chemical signals such as human sweat and exhaled gases, thereby reducing their tendency to attack.


2. Versatile application forms and convenient use

DEET can be formulated into various forms such as sprays, lotions, and wipes, and can be directly applied to the skin or clothing surface. It is suitable for outdoor activities, travel, military operations, and other scenarios. Its protective duration increases with concentration (e.g., 20%-30% concentration provides protection for several hours to several days), allowing users to flexibly choose based on their needs.
