A dispersion liquid contains fine particles of core-shell type inorganic oxide that have high dispersion stability and transparency and allow for excellent light resistance and weather resistance by being mixed in a coating film. The fine particles are produced by treating the surfaces of (a) fine particles of titanium-containing metal oxide serving as core particles with a hydrate and/or an oxide of a metal element such as zirconium to provide surface-treated particles or fine particles of titanium-containing metal oxide having (b) an intermediate layer and by covering the surfaces of the surface-treated particles to form (c) a shell layer with a composite oxide of silicon and at least one metal element selected from aluminum, zirconium, and antimony.

It is an object of the present invention to provide a deodorant or a deodorant composition which has excellent deodorizing performance with respect to sulfurous stench from methyl mercaptan and hydrogen sulfide and the like. It is another object of the present invention to provide a deodorant or a deodorant composition which maintains a deodorizing effect with respect to sulfurous stench and which makes it possible to suppress resin deterioration in the case of being kneaded into a resin, and a deodorizing product containing the same. A deodorant of the present invention contains amorphous copper silicate represented by the following formula [1]:

xNa.sub.2O.yCuO.SiO.sub.2.zH.sub.2O   [1]

wherein, in formula [1], x is a positive number from 0.002 to 0.040, y is a positive number from 0.07 to 0.48, and z is a positive number from 0.02 to 0.30.
