  • The penetrating speeds of organic solvents into the nude mouse skin were measured by in vitro methods(diffusion cell methods) and in vivo methods(measuring internal residues of the organic solvents). The results were as follows: 1. The penetrating speeds of toluene, m-xylene, MEK, MIBK, ethanol, IPA and 2-bromopropane into the skin were $0.4832mg/cm^2/h$, $0.1738mg/cm^2/h$, $1.124mg/cm^2/h$, $0.6627mg/cm^2/h$, $1.747mg/cm^2/h$, $1.359mg/cm^2/h$, and 2-bromopropane $4.165mg/cm^2/h$ respectively. 2. The penetrating speeds of the mixtures of two, toluene and m-xylene, the mixture of three, IPA, ethyl acetate, and MIBK, the mixture of five, toluene, m-xylene, IPA, ethyl acetate, and MIBK were $0.172mg/cm^2/h$, $1.431mg/cm^2/h$, and $2.983mg/cm^2/h$ respectively. 3. The absorption speeds of 2-bromopropane and styrene which were measured by in vivo processes were $3.12mg/cm^2/h$ and $1.44mg/cm^2/h$ respectively. The absorption speed of 2-bromopropane mesured in vivo was 74.9% of that measured by in vitro methods, $4.165mg/cm^2/h$.
