Title: Nariyuki Kurotani: Innovator in Cosmetic Chemistry
Introduction
Nariyuki Kurotani is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of cosmetic chemistry, particularly through his innovative patents. With a total of 3 patents to his name, Kurotani has focused on enhancing cosmetic formulations to improve their effectiveness and user experience.
Latest Patents
Kurotani's latest patents include a barium sulfate cosmetic composition and a process for preparing barium sulfate. The barium sulfate composition features a specific crystal structure and optical characteristics. The crystals possess a plate-like structure with an aspect ratio ranging from 5 to 100. Additionally, the ratio of the square of the circumference of the plate to the area of the orthogonal projection plane is between 20:1 and 150:1. In a preferred embodiment, a thin film of 25 µm thickness with a 20% by weight concentration of barium sulfate powder achieves a scattering transmittance of 70% or greater and a total transmittance of 85% or greater. The cosmetic compositions incorporating this barium sulfate exhibit excellent extendibility and adhesion to the skin, effectively concealing spots or freckles. This innovative composition satisfies both the fine naked skin feeling and the skin covering effect, which have not been achieved by conventional cosmetic products.
