Colorful TiO₂Particle

Wide colored pigment without transition metals

Overview

　Transition metal doping is one of the solution to colorize inorganic pigments. This method is adoptive to TiO2 pigments, however, transition metal-doped pigments are not sufficient for cosmetic products as transition metals have ecotoxicity.

　This invention realized wide variety of colored TiO2 pigments without transition metal doping, such as RGB as shown right half of this paper.

　This invention is expected to expand cosmetic product applications, or replace traditional organic and inorganic materials.

Wide variety of color by process control

Product Application

・Cosmetic products
・Inorganic pigments required atoxic
