Insights into the Dermal Absorption, Percutaneous Penetration, and Tissue Distribution of Quaternary Ammonium Compounds (QACs): Evidence from Human Skin Wipes and In Vivo Rat Models

values, molecular weights, and chain lengths, with varied correlations among different QAC categories. Fecal excretion was identified as the main elimination route for dermally adsorbed QACs. Exposure assessment emphasized the significance of dermal exposure to QACs.
