Pesticide Science, 1977
AbstractThe new pyrethroid, permethrin, previously shown to have high activity against textile pests, was successfully applied to wool from a conventional dye bath. The stability of permethrin to boiling aqueous conditions and to some textile testing regimes was shown to be satisfactory, although some loss on prolonged boiling did occur.

Pesticide Science, 1986
AbstractThe vapour pressures of the separate isomers of permethrin have been determined over a range of temperatures by two laboratories using different versions of the gas saturation method. A statistical analysis of the sets of data from the two laboratories shows no significant differences for the cis isomers but a small difference in the 20°C ...

Wearing of permethrin treated clothing usually implicates an uptake of permethrin by the user. Aim of our study was to examine the kinetics of internal permethrin exposure in volunteers during and after a single 8h-use of treated clothing as well as factors potentially influencing permethrin uptake.

A new treatment regimen with permethrin in scabies
Italian Journal of Dermatology and Venereology, 2018Topical permethrin, applied once daily, is considered as the most effective treatment in scabies.Eighty-nine adult immunocompetent patients with scabies were treated with 5% permethrin cream: 42 patients were treated with a single application/day (group 1); 47 patients were treated with one application/day for two consecutive days (group 2).

Journal of Apicultural Research, 1989
SummaryA laboratory study was conducted to test the pyrethroid insecticide, permethrin, separately and in combination with piperonyl butoxide (PB) at ratios of 1 part insecticide to 4 and 9 parts PB. Foraging honeybees, Apis mellifera L., were exposed to treated filter paper to determine toxicity and synergistic effects between the binary mixtures ...

The Efficacy of Permethrin Lotion in Pediculosis Capitis
International Journal of Dermatology, 1985ABSTRACT: A clinical trial of the pyrethroid permethrin in 1% lotion was performed on 20 children. Ten were treated for 10 minutes and 10 for 2 hours. All lice washed off the heads of children treated for 2 hours were dead immediately after treatment.

Exposure to permethrin and cancer risk: a systematic review
Critical Reviews in Toxicology, 2018No systematic reviews are available on data from humans on cancer risk from exposure to permethrin, a widely used insecticide for which some animal studies have reported positive findings based on mechanisms that may not be relevant to humans.

Permethrin toxicity in exotic pets
Veterinary Record, 2010Permethrin toxicity in cats has rightly received much attention recently (see, for example, VR , February 27, 2010, vol 166, [p 281][1]). I take this opportunity to remind colleagues that permethrin and other pyrethroids are also poisonous to other pet species, including arachnids, fish and ...
