reported a much higher
percentage of the dose removed by the skin wash. They used an
organic solvent, isopropanol, to wash the skin, whereas we used a
soap and water mixture. Since the pyrethroids are lipophilic, with a
log octanol:water partition coefficient (Log P) 4.5 or greater (Table 1),
it seems reasonable that a wash with an organic solvent would
remove a higher percentage of the dose than a wash with soap and
water
