Abstract

Stearyl alcohol was layered on a filter paper support and tested for resistance to O2 and water vapor transmission following tempering. Tempering at 48C for 14 or 35 days caused the resistance to O2 and water vapor transmission to increase. The resistance to O2 and water vapor transport was increased 80% and 50% respectively, after 35 days. Likely mechanistic explanations include the healing of crystal imperfections and the development of a more extensive and betterlinked arrangement of lipid crystalline platelets.
