However, using mouse skin, they did
observe b2% of the dose in the receptor fluid over 24 h following its
application in acetone or dimethylsulfoxide. They did not report on
the percentage of the dose in the wash and skin. In another study by
Baynes et al. (2002), using pig skin in a flow-through cell system, b1%
of the dose (ca. 65 nmol, 102 nmol/cm2) was detected in the receptor
fluid after an 8 h exposure to permethrin. About 50–70% of the dose
was removed by a skin wash (soap/water), 10–20% was in the
stratum corneum (removed by tape-stripping), and 2–5% was in the
tape-stripped skin.
