Zusammenfassung:	This disclosure relates to a polymer composition comprising an inorganic particle, wherein the inorganic particle comprises at least about 0.002% of tungsten, based on the total weight of the inorganic particle, and has a photostability ratio (PSR) of at least about 2, as measured by the Ag+ photoreduction rate, and color as depicted by an L* of at least about 97.0, and b* of less than about 4. The disclosure also relates to plastic parts prepared from these compositions.
