Title:
TITANIUM OXIDE POWDER, AND DISPERSION LIQUID AND COSMETIC USING SAID POWDER
Document Type and Number:
WIPO Patent Application WO/2019/131830
Kind Code:
A1
Abstract:
This titanium oxide powder has a BET specific surface area of 5 m2/g to 15 m2/g. The titanium oxide powder contains octahedral particles for which the average value of the maximum values of line segments connecting two facing vertices is 300 nm to 1000 nm, and a value (D90/D10) obtained by dividing the value (D90) when the cumulative percentage by number reaches 90% for the maximum values of the line segments connecting two facing vertices by the value (D10) when the cumulative percentage by number reaches 10% for the same is 1 to 3.
