This disclosure relates to inorganic particles, typically inorganic metal oxide or mixed metal oxide particles, and more typically titanium dioxide (TiO 2 ) particles, comprising at least about 0.002 % of tungsten, based on the total weight of the inorganic particles, wherein inorganic particles have 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. These titanium dioxide particles comprising tungsten may further comprise alumina. |
