Development of Control Methods for Submicron Particulate Matter Emissions and Inhalation Exposure from Cosmetic Spray Products.

ABSTRACT: Cosmetic spray products, widely used for personal care, are popular due to their ease of application and rapid, uniform coverage. However, the particulate matter (PM) that they emit can be inhaled and deposited in the respiratory tract, potentially posing respiratory health risks. Existing studies have seldom addressed emissions from cosmetic spray products applied directly to the human body, especially the face and neck, and few have proposed practical methods to reduce exposure. This study systematically evaluates the particle size distribution and number- and mass-based concentrations of 12 products under a laboratory setting that simulated real-use conditions. It is found that PM emissions from some spray products could be significant and strongly influenced by nozzle design and produc
