Method for producing spherical zinc oxide

Method for producing Monodispersed spherical zinc oxide having uniform particle diameter

Overview

　Zinc oxide is used as an ultraviolet shielding agent in cosmetics such as sunscreens. However, in the conventional manufacturing technology, it was difficult to control the particle size of zinc oxide, and it was considered that the texture was bad. Furthermore, there is concern about the effects on the environment and the human body due to toxic exhaust gas caused by treatment at high temperature and the use of inert gas in the manufacturing process. The present invention relates to a method for producing spherical zinc oxide with uniform particle size and monodisperse, and spherical zinc oxide with a simple, low cost and low environmental impact. The spherical zinc oxide is expected to be used as a cosmetic with high ultraviolet shielding effect, excellent soft focusing property and excellent usability.
