To provide fine particulate titanium dioxide composition wettable with water and having excellent water dispersibility, ultraviolet shielding power, discoloration resistance and production workability.

The objective fine particulate titanium dioxide composition is produced by using a fine titanium dioxide particle having maximum particle diameter of ≤0.1 μm and an average primary particle diameter of 0.01-0.08 μm as a core particle, coating the surface of the core particle with an inner layer consisting of 8-15 wt.% of a high-density silicon oxide in terms of SiO2 based on the fine titanium dioxide particle, coating the product with an intermediate layer consisting of 5-10 wt.% of hydrated aluminum oxide in terms of Al2O3 based on the fine titanium dioxide particle and finally coating the surface with an outer layer consisting of 2-7 wt.% of alginic acid based on the fine titanium dioxide particle.
