WebThe modified Potts-Guy equation is based on results obtained in vitro. Traditional PBPK models have often not included a skin compartment. In order to evaluate dermal exposure, the investigators cited above modified PBPK models by adding skin compartments. There are several ways that the skin can be represented in a PBPK model. WebThis equation was based on molecular weight (MW) and the octanolwater partition coefficient (log P). To identify a mathematical model predictive of the mostly unexplored skin penetration of fragrance chemicals, the Potts-Guy equation was tested here by correlating the published, measured Kp for 20 such compounds with predicted Kp values.
