  • Patent number: 11312902
    Abstract: 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.
    Type: Grant

  • Patent number: 11154469
    Abstract: 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 CaaPbOc (3.2?a?5.0, b=2, c=a+5) and having an average particle diameter of from 1 to 10 ?m.

  • Patent number: 11020331
    Abstract: 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 I2/I1 of 1 to 30, where I1 is a maximum emission intensity in the range of 530 to 620 nm and I2 is a maximum peak intensity in the range of 620 to 720 nm.
