Characterization of compositional particles in eye shadow powder by scanning electron microscope and X‐ray mapping

Abstract We developed an analysis method to evaluate the size and shape of particles of eye shadow cosmetics by applying the scanning electron microscopy (SEM) combined with the energy‐dispersive spectroscopy (EDS). Backscattered electron (BE) and X‐ray mapping images from the SEM‐EDS measurements were interpreted to identify the size and shape of powder particles according to different factors such as 9 size and 5 shape indices established in this work. By using the developed method, we could classify the inorganic and organic particles of the eye shadow powder by composition, which can contribute to improving the product quality.
