Abstract
Sorption of ethanol and water into stratum corneum, delipidized stratum corneum, and triolein as a simple model lipid was investigated. Optima in ethanol sorption and flux are related to dehydration of keratins. There was no optimum for solubility in triolein; a linear cosolvency is observed with ethanol:triolein mixtures. A model is proposed which qualitatively predicts the key features of ethanol-enhanced skin permeation on the basis of these solubility phenomena and a constant diffusion coefficient.
