ABSTRACT:
Titanium oxide particles comprising particulate titanium oxide substrate having a zinc oxy compound or a combination of a zinc oxy compound and a silicon oxy compound supported thereon. They can be produced by adding a zinc compound or a combination of a zinc compound and a silicon compound together with an alkali to a dispersion of particulate titanium oxide substrate to neutralize the zinc compound or the combination of the zinc compound and the silicon compound in said dispersion, then separating and drying the resultant product. They are useful for pigments, catalysts, catalyst supports and adsorbents, and particularly excellent in deodorizing performance by removing malodorous gases such as ammonia, methyl mercaptan, hydrogen sulfide, trimethylamine, methyl sulfide and acetaldehyde through decomposition and adsorption thereof, so that they are useful as white deodorants for sanitary objects such as paper diaper and sanitary napkins which come to directly contact with the skins of human beings.
