N,N-DIETHYL-M-TOLUAMIDE CAS 134-62-3

1. Core application: Human insect repellent products (mainstream uses)

Diethyltoluamide DEET is the core active ingredient in commercially available human mosquito repellent products. By forming an "odor barrier" on the surface of the skin or clothing, diethyltoluamide blocks insects from passing on volatile substances in human sweat and breathing, thereby preventing bites. Common product forms include:

Direct application/spraying type Mosquito repellent flower water, mosquito repellent spray, mosquito repellent lotion, mosquito repellent ointment, etc., usually contain 5% to 30% concentration of deet (the concentration of children's products is mostly less than 10%), which can provide continuous protection for 2 to 8 hours and can repel mosquitoes (especially Anopedes and Aedes mosquitoes that spread malaria and dengue fever), flies, fleas, lice, ticks and many other blood-sucking insects.

Portable protective types: Mosquito repellent wristbands (which adsorb deet in a carrier and release it slowly), mosquito repellent stickers (attached to the surface of clothing/skin through gel or sticker carriers), suitable for outdoor and travel scenarios, emphasizing convenience.

2. Animal deworming field

Diethyltoluamide DEET is also registered for deworming protection of animals, especially pets and livestock, and is mainly used for:

Pet protection: Add to pet-specific mosquito repellent sprays, insect repellent collars, and insect repellent drops to help cats, dogs and other pets avoid being bitten by mosquitoes, fleas and ticks, and reduce the risk of skin diseases or parasitic diseases.

Livestock protection: Partially used in deworming products for livestock such as cattle and sheep, diethyltoluamide deet reduces the impact of mosquito bites on the growth of domestic animals, and decreases the stress response or disease spread caused by bites.

3. Addition of daily necessities functions

To enhance the "mosquito repellent property" of products, diethyltoluamide is added in small amounts as a functional ingredient to specific daily items, such as:

Textile category: Mosquito-proof clothing (such as outdoor quick-drying clothes, children's pajamas), by attaching diethyltoluamide to the fabric fibers, a long-lasting mosquito-proof layer is formed, which can still maintain a certain repellent effect after washing.

Skin care products/cleaning supplies: Some outdoor-specific skin care products (such as sunscreen and mosquito repellent two-in-one products) and summer-specific shampoos will add low-concentration deET to meet the needs of both skin care and mosquito prevention (must comply with relevant safety standards).

4. Special scenario protection

In scenarios with a high concentration of mosquitoes and a high risk of disease transmission, Diethyltoluamide DEET is an important protective auxiliary ingredient, for example:

Outdoor operations/exploration: High-concentration (such as 30%-50%) mosquito repellent products used by forestry, geological exploration, and field researchers need to deal with complex mosquito environments.

Public health prevention and control: In areas with a high incidence of vector-borne infectious diseases such as viruses, diethyltoluamide products are one of the personal protective measures recommended by disease control departments, helping to reduce the transmission routes of viruses.
