Titanium oxide powder, and dispersion liquid and cosmetic using said powder

Abstract

The titanium oxide powder of the present invention is a titanium oxide powder which has a BET specific surface area of 5 m2/g or more and 15 m2/g or less, and contains octahedral-shaped particles, wherein each octahedral-shaped particle thereof has line segments each of which connects two apexes which face each other and has a maximum value of the line segments, an average value of the maximum values is 300 nm or higher and 1000 nm or lower, and a value (D90/D10) is 1 or higher and 3 or lower, wherein the value is obtained by dividing a value (D90), which corresponds to 90% in a cumulative number percentage of the maximum values of line segments each of which connects two apexes which face each other, by a value (D10) which corresponds to 10% in the cumulative number percentage.
