Description and Uses
Yellow-brown to brown liquid, which sometimes tends to crystallize at room temperature (technical grade).
Permethrin, a pyrethroid insecticide with little mammalian toxicity, has been marketed as a tick repellent. Permethrin is the only synthetic pyrethroid that is used worldwide for head lice. The spray formulation is the most widely available form. Once applied to clothing, it is stable through several wash cycles. It is also suitable for treating sleeping bags, tents, and fabric used for insect screening. A liquid concentrate has been used to impregnate fabric for as long as the life of the garment. Permethrin is particularly helpful in the prevention of tick and chigger bites. These crawling arthropods must travel across the treated fabric, whereas flying insects tend to be attracted directly to exposed skin. The combination of a DEET-containing repellent and permethrin-treated clothing is generally highly ffective against a wide range of biting arthropods.
For the treatment of infestation with Sarcoptes scabiei (scabies); antihyperlipidemic; cholesterol sequestrant.
