6 вещей, которые вам нужно знать о ДЭТА

DEETCAS 134-62-3, short for N, N-diethyl-m-toluamide, is a widely known insect repellent that has been a must-have for outdoor activities for decades. Effective against a variety of biting insects, including mosquitoes and ticks, it is a must-have for camping, hiking, and other outdoor adventures. However, with the widespread use of DEET, questions have been raised about its safety and potential health effects. Here, we will explore six basic aspects of DEET, from its composition to safe use guidelines.

What is DEET?

Definition and Chemical Composition
DEET（CAS 134-62-3） is a synthetic chemical compound that is primarily used as an insect repellent. Its molecular formula is C12H17NO2, and it works by interfering with the ability of insects to detect human odor. By masking our natural odor, DEET can effectively repel pesky bugs.

How DEET Works as an Insect Repellent
DEET works by targeting receptors that insects use to locate their hosts. By inhibiting these receptors, DEET makes it difficult for insects to find humans, thereby providing protection against bites and reducing the risk of insect-borne diseases.

Safety of DEET

Overview of Regulatory Approvals (e.g., EPA, CDC)
DEET has been extensively tested and reviewed by regulatory agencies. The EPA has determined that DEET is safe for adults and children over two months of age at concentrations up to 30%.

Recommended Concentrations for Safe Use
Most commercial DEET products are available in concentrations ranging from 5% to 100%. For recreational outdoor activities, products with DEET concentrations of 10% to 30% are generally sufficient. Higher concentrations are not necessarily more effective and may carry a greater risk of skin irritation.

Potential Health Effects

A. Short-term Exposure
Skin Irritation and Allergic Reactions: Some users may experience skin irritation or allergic reactions, especially with prolonged contact. Patch testing on a small area of ​​skin is recommended prior to full application.

Eye Irritation: DEET can cause severe eye irritation if it comes into contact with the eyes. Users should be careful to avoid applying it to the face or near the eyes.

Effects of Inhalation: While generally safe when used properly, inhaling large amounts of DEET vapor can cause respiratory irritation. Always use in a well-ventilated area.

B. Long-term exposure
Potential systemic effects on the body: Research on long-term exposure to DEET is limited but suggests that excessive use may cause systemic effects, especially in sensitive populations.

Long-term use study results: Studies examining long-term use of DEET indicate few adverse effects, but ongoing monitoring is recommended, especially for frequent users.

Vulnerable populations (children, pregnant women): Particular caution is recommended for children and pregnant women. CDC recommends that DEET be used with older children and pregnant women consult a healthcare provider before use.

Myths and Myths

Common Myths About DEET Toxicity
There are many misconceptions about the safety of DEET. A common myth is that DEET is highly toxic and should be avoided at all costs. However, health authorities consider DEET to be safe when used properly.

Comparison with other repellents (e.g. natural alternatives)
While natural repellents such as citronella or eucalyptus oil are popular, they generally provide shorter protection than DEET. Understanding their effectiveness can help users make an informed choice based on their activity level and environment.

Guidelines for Safe Use

To maximize safety when using DEET, always follow these recommendations:

Apply only to exposed skin and clothing.
Avoid application to the areas around the eyes and mouth.
Wash applied skin when you return indoors.
What to avoid (e.g., use on broken skin, avoid ingestion)

Avoid applying DEET to broken or irritated skin, and make sure it does not come into contact with mucous membranes. Ingesting DEET can cause serious health problems, so keep it out of the reach of children.

Always read and follow the instructions on the product label as it contains important information about concentration, usage, and safety precautions.
