Influence of Temperature, Humidity, Personal Hygiene, and Clothing on the Ozonolysis of Skin Oil at the Skin's Surface: Self Regulation.

ABSTRACT: Reactions between skin oil and ozone are a substantial source of volatile organic compounds (VOCs) emitted from the human body, yet factors influencing these reactions and emissions have only recently begun to be investigated. In this study, we conducted single-person chamber experiments involving three volunteers to systematically assess the influence of various factors, including temperature, relative humidity (RH), personal hygiene (bathing frequency and clothing soiling), and clothing coverage. We found that chamber air temperature and RH, within the range of 22-31 °C and 40-70% respectively, had negligible effects on ozone-driven VOC emissions, likely due to the body's regulation of its surface temperature and humidity. This finding contrasts with the pronounced RH dependence reported
