SURFACE-TREATED METAL OXIDE PARTICLES, LIQUID DISPERSION, COMPOSITION, COSMETIC, AND METHOD FOR PRODUCING SURFACE-TREATED METAL OXIDE PARTICLES

Document Type and Number:

WIPO Patent Application WO/2020/067406

Kind Code:

A1

Abstract:

Surface-treated metal oxide particles each of which is surface-treated with a silane coupling agent and which have ultraviolet ray-blocking properties, wherein, in spectra of the surface-treated metal oxide particles as measured by solid 29Si CP/MAS-nuclear magnetic resonance (NMR) spectroscopy, when the integrated value of spectra in a measurement range from -20 ppm to -80 ppm is defined as 100%, the ratio of the integrated value in a range from -20 ppm to -50 ppm is 60% or less.
