ALLETHRINS

Description

Allethrins are a group of synthetic pyrethroid insecticides derived from chrysanthemum flowers. These compounds are widely used in household and agricultural pest control products due to their effectiveness against flying and crawling insects. Allethrins work by interfering with the sodium channels in insect nerve cells, leading to paralysis and death.

The most common forms include d-allethrin, bioallethrin, and s-bioallethrin. These compounds are generally considered to have low toxicity to mammals when used as directed, but can cause skin irritation and allergic reactions in sensitive individuals. Allethrins break down rapidly when exposed to sunlight and air, reducing environmental persistence.

In skincare and personal care products, allethrins may be found in insect repellents and anti-lice treatments. However, their use in leave-on cosmetic formulations is limited due to potential irritation. When formulating with allethrins, it's crucial to consider concentration limits, product type, and potential interactions with other ingredients. Proper labeling and safety precautions are essential, as allethrins can be harmful if ingested or excessively absorbed through the skin.
