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.
Claims7
A cosmetic product comprising
- 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,
- wherein the cosmetic product contains a mixture containing:
- a phosphor containing at least one selected from the group consisting of
- a complex oxide containing Mn in a compound of the following formula (1), the Mn being present in a proportion of 0.00005 to 0.05 mol relative to 1 mol of magnesium in the compound:
- MgxTiyOz (1)
- wherein x, y, and z satisfy 1.5<x<2.5, 0.5<y≤1.5, and z=x+2y, and
- a complex oxide containing Mn in a compound of the following formula (2), the Mn being present in a proportion of 0.000042 to 0.0083 mol relative to 1 mol of aluminum in the compound:
- CaxAlyOz (2)
- wherein x, y and z satisfy 0.1<x<1.05, 11.9<y≤12, and z=(2x+3y)/2;
- and
- a phosphor containing at least one selected from the group consisting of
- a complex oxide containing Ce in a compound of the following formula (3), the Ce being present in a proportion of 0.0005 to 0.05 mol relative to 1 mol of phosphorus in the compound:
- CaxPyOz (3)
- wherein x, y and z satisfy 3.2≤x≤5.0, 1.9≤y≤2.1, and z=x+5, and
- a fluorescent zinc oxide.
