4 Pharmacology and Biochemistry
4.1 Absorption, Distribution and Excretion

The penetration of methyl benzoate ... through excised guinea pig dorsal skin was measured using diffusion cells. The permeability coefficient (Kp) /was/ 20.3 +/- 5.8x10-2 cm/hr ... indicating significant steady-state dermal penetration. Permeability was increased by removal of the stratum corneum by tape stripping and delipidization using a chloroform-methanol mixture. Penetration was decreased by the addition of 1-methanol plus 15% ethanol.
