The present invention provides a method for easily and simply producing a zinc oxide phosphor that has a high level of safety and a high emission intensity and is useful for, for example, cosmetic applications. The present invention also provides a zinc oxide phosphor having such excellent physical properties and a cosmetic product containing the same. Provided is a method for producing a zinc oxide phosphor, including: a raw material mixing step of mixing an oxygen-containing zinc compound and a sulfur-containing compound; and a firing step of firing the raw material mixture obtained in the raw material mixing step, the firing step including firing in a reducing atmosphere followed by firing in an oxygen-containing atmosphere.

Zinc oxide phosphor and method for producing same

The present invention provides a cosmetic product capable of making the skin look youthful and producing a natural three-dimensional appearance. The present invention relates to a cosmetic product including two or more phosphors each containing an inorganic compound, wherein the cosmetic product, upon excitation by excitation light having a wavelength of 365 nm, emits an emission spectrum having a fluorescence emission peak in each of the range of 400 to 530 nm and the range of 620 to 720 nm and having an I/Iof 1 to 30, where Iis a maximum emission intensity in the range of 530 to 620 nm and Iis a maximum peak intensity in the range of 620 to 720 nm.
