General Information:
CAS NO.: 52645-53-1
Molecular Formula: C21H20Cl2O3
Molecular Mass: 391.2877
Appearance: Yellow to brown liquid
EINECS: 258-067-9
Permethrin mass fraction : more than 95%
Functions :
1: Permethrin is an insecticide used to prevent infestation with Sarcoptes scabiei .
A pyrethroid insecticide commonly used in the treatment of lice infestations and scabies.
2: It is a yellow to light orange-brown, low melt-ing solid or viscous liquid.
3: Permethrin acts on the nerve cell membrane to disrupt the sodium channel current by which
the polarization of the membrane is regulated. Delayed repolarization and paralysis of the pests
are the consequences of this disturbance.
Route of elimination :
Permethrin is rapidly metabolized by ester hydrolysis to inactive metabolites which are excreted primarily in the urine.
Insecticide
In agriculture, to protect crops (a drawback is that it is lethal to bees)
In agriculture, to kill livestock parasites
For industrial and domestic insect control
In the textile industry, to prevent insect attack of woollen products
In aviation, the WHO, IHR and ICAO require arriving aircraft be disinsected prior to embarkation, departure, descent, or deplaning in certain countries. Aircraft disinsection with permethrin-based products is recommended only prior to embarkation. Prior to departure (after boarding), at the top of descent or on arrival, d-phenothrin-based (1R-trans phenothrin) aircraft insecticides are recommended.
Permethrin is available for topical use as a cream or lotion.
For treatment of scabies。
For treatment of head lice: Apply to hair, scalp, and neck after shampooing.
Leave in for 10 minutes and rinse. Avoid contact with eyes.
