Title:
METHOD FOR PREPARING SILICA HAVING ULTRAVIOLET BLOCKING EFFECT, AND SILICA HAVING ULTRAVIOLET BLOCKING EFFECT, PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2024/063213
Kind Code:
A1
Abstract:
A method for preparing silica having an ultraviolet blocking effect, and silica having an ultraviolet blocking effect, prepared thereby are disclosed. According to the method for preparing silica having an ultraviolet blocking effect, and the silica having an ultraviolet blocking effect, prepared thereby, of the present invention, a template is not used during silica preparation, and thus preparation steps are simpler and more convenient, preparation time can be reduced, the difficulties of template manufacturing and template removal, caused by the application of a template during silica preparation, can be overcome, and production costs can be reduced even while the particle size and shape of silica are implemented as desired by a manufacturer. In addition, provided is silica applied to an ultraviolet screening agent so as to improve ultraviolet screening efficacy.
