Abstract

It is an object of the present invention to provide hexagonal prism-shaped zinc oxide particles which have a specific particle diameter and a specific aspect ratio, and high ultraviolet blocking performance and transparency, and therefore can be suitably used as a cosmetic and a heat releasing material. Provided are hexagonal prism-shaped zinc oxide particles having a primary particle diameter of 0.1 μm or more and less than 0.5 μm and an aspect ratio of less than 2.5.
