In this study, several powdered cosmetic products were purchased and evaluated for the presence of TiO2 nanoparticles first by automated particle sizing using scanning electron microscopy (SEM) with chemical typing by energy dispersive spectroscopy (EDS) and then by transmission electron microscopy (TEM). Our results show that automated particle sizing/chemical typing by SEM-EDS is a convenient screening tool for detection of nanoparticles (to 50 nm) and determination of elemental composition. This analysis may be followed up by TEM for a detailed investigation of morphology, and to assess the lower particle size limit and any association with other ingredients. Additionally, the results of a study on TiO2 nanoparticle release in the breathing zone during cosmetic application will be presented.
