Abstract:
KEYWORDS: Asbestos, Powdered-cosmetic talc, SEM-EDS, SR SAXS, SR IR
It is well-known that asbestos is a fiber causing lung diseases, such as asbestosis and mesothelioma. Talc is used for commercial applications such as paints, plastics, papers, ceramics, construction materials, and cosmetics. It is found that the cosmetic talc powder is used for preventing diaper rash, as a deodorant. Samples of cosmetic talc powder are selected from the various markets in Thailand. A scanning electron microscope coupled with an energy dispersive X-ray spectrometer (SEM-EDS) is used to characterize the microstructure and elemental composition. The facilities of synchrotron radiation such as small-angle X-ray scattering (SR SAXS) and infrared spectroscopy (SR IR) are also carried out to determine their phase composition and functional groups. It is found that some samples showed like-asbestos structures. Their compositions are mainly contained with silica and magnesium. The various constituents of the composition are in the form of the functional groups along with wavenumber.
