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

To obtain an inorganic blue fluorescent material that is composed of elements for which there are no suspected harmful effects on humans, and that has excellent texture when applied to skin. A fluorescent material for a cosmetic being a composite oxide containing from 0.0005 to 0.05 (in terms of a mole ratio relative to 1 mol of phosphorous in a molecule) of Ce in a compound represented by general formula CaPO(3.2&#x2264;a&#x2264;5.0, b=2, c=a+5) and having an average particle diameter of from 1 to 10 &#x3bc;m.

Fluorescent material for cosmetics, and cosmetic

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.
