Title: TITANIUM OXIDE PARTICLES, AND TITANIUM OXIDE PARTICLE DISPERSION AND COSMETICS USING SAME
Abstract:
These titanium oxide particles include octahedral-shaped particles which have an average value of maximum values of line segments connecting two opposing apexes of a particle of 300 to 1000 nm, the average value of the maximum values divided by the average particle size converted from the BET specific surface area (average value of maximum values/BET converted average particle size) being 1.0 to 2.5.
