Predicting chemical emissions from household cleaning and personal care products: A review

Chemicals in household cleaning and personal care products (HCPs PCPs) can be released into the indoor air primarily during after product use, leading to human exposures these chemicals via inhalation dermal contact. Thus, HCPs PCPs are a group of important intermittent sources, contributing chemical emissions environment. To characterize more accurately, we reviewed three types emission models from 18 studies for PCPs, i.e., based on evaporation, convective mass transfer, diffusion. While present different levels complexity, they cover variety application scenarios. We also summarized some input parameters models, frequency quantity use chemical's evaporation rate diffusion coefficient. The many products, including shampoo, hand soap deodorant show consistency among studies. Our review model inputs reveals promising basis further improvement PCPs.
