Laboratory Method to Determine the Retention of Liquids on the Surface of Hands.

摘要

The purpose of the report is to present data collected in three laboratory trials designed to quantify the amount of liquid deposited onto the surface of hands. The information is needed to calculate dermal exposure using the film thickness model developed in Volume 7 of the Methods for Assessing Consumer Exposure to Chemical Substances series (EPA 560/5-85-007). The study focuses on retention on hands of three nonaqueous liquids, bath oil, cooking oil, and mineral oil. For each subject-liquid combination, three different methods of liquid application, or testing, were employed: initial wipe, secondary wipe, and immersion. The amount ofliquid retained on the hands of the four subjects was measured immediately after the application and also after subsequent partial and full removals by a dry cloth designed to remove liquid from the hands.
