Latest Patents

Hiroshi Suganuma holds a patent for "Barium sulfate and cosmetic compositions comprising same." This patent discloses barium sulfate with a specific crystal structure and optical characteristics. The crystals possess a plate-like structure with an aspect ratio ranging from 5 to 100. 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 demonstrate excellent extendibility and adhesion to the skin, effectively concealing spots or freckles. This innovation satisfies both the fine naked skin feeling and the skin covering effect, which have not been achieved by conventional cosmetic compositions.
