β¦ Synopsis
A model for estimating in vivo skin permeability coefficients for finite doses is presented. The ratio of the maximum value of the excretion rate to the steady-state flux is a function of the thickness of the applied vehicle and the vehicle-skin partition coefficient. The decay rate of the excretion is a function of skin-vehicle parameters for large doses and, under certain conditions, can even reduce to the total excretory rate constant as the dose is decreased.

A diffusion model to account for the disposition of an arbitrary dose of a (potentially) volatile compound applied to skin from a volatile vehicle is presented. In its most general form, the model allows for variable diffusivity of the permeant in the stratum corneum (SC) and must be solved numerica
