Document Type and Number:
WIPO Patent Application WO/2022/119420
Kind Code:
A1
Abstract:
The present invention relates to: a polymer carbon nitride; a specific crystal form of the polymer carbon nitride; and a cosmetic composition, an ultraviolet ray-blocking composition, and an external use skin preparation composition which include the polymer carbon nitride. The polymer carbon nitride according to one aspect of the present invention and a crystal form prepared by a specific preparation example thereof can absorb both UVA and UVB, and thus can effectively protect the skin from ultraviolet rays while also being non-toxic and thus suitable for living bodies and lacking photoactivity. Therefore, the polymer carbide nitride and the crystal form can be utilized in a cosmetic composition, an ultraviolet ray-blocking composition and an external use skin preparation composition which are applied to living bodies. In addition, the specific crystal form of the polymer carbon nitride has different characteristics according to the preparation method, and thus can be variously utilized according to the characteristics thereof. Particularly, the crystal form of the polymer carbon nitride according to one aspect can be adjusted to various colors according to the preparation method, and thus can be utilized to obtain a composition having a desired color. Therefore, the crystal form can be suitably utilized to produce products of various colors suitable for the skin tones of individuals.
