Abstract: Very little permeation work has addressed the breakthrough of a complex mixture such as a commercial pesticide formulation through protective glove materials. To evaluate the factors that affect the breakthrough time of the pesticide active ingredient, the ASTM permeation cell system was used with two thicknesses of butyl rubber, three common pesticide commercial formulations and elevated temperatures (35°C, 45°C, 55°C). It was found that polymer/solvent interaction, glove thickness, and temperature play a crucial role in breakthrough time. Where the Hansen 3-dimensional solubility parameters of the glove polymer and pesticide formulation solvent were similar the breakthrough time of the active ingredient was practically instantaneous regardless of glove thickness and temperature. Degradation was the primary breakthrough mechanism.
