Title:
COMPOSITION FOR UV ABSORPTION AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2024/009548
Kind Code:
A1
Abstract:
Provided are: a composition for UV absorption having excellent dispersibility while having an excellent UV absorption function, in particular absorbing UVA (wavelengths of 315-380 nm) and UVB (wavelengths of 280-315 nm); a method for manufacturing the same; and a UV absorption method in which the same is used. This composition for UV absorption contains carbon-based quantum dots, an aqueous solvent, a surfactant, and an oil-based base. Alternatively, this composition for UV absorption contains carbon-based quantum dots, an aqueous solvent, and a hydrophilic base. This method for manufacturing a composition for UV absorption includes a step for mixing a water dispersion containing carbon-based quantum dots and an aqueous solvent, a surfactant, and an oil-based base. This method for manufacturing a composition for UV absorption includes a step for mixing a water dispersion containing carbon-based quantum dots and an aqueous solvent, and a hydrophilic base.
