Abstract: PROBLEM TO BE SOLVED: To obtain a red pigment controlled in the spectral reflectance of the pigment itself and being capable of controlling the spectral reflectance of a cosmetic containing the pigment by using a complex oxide of Ca and Fe. SOLUTION: This pigment comprises a double oxide of the formula: Cax Fey Ox+(3y/2) (wherein x is 0.6-2; and y is 2-3). By controlling the deflection point wavelength (the wavelength at which the first-order differential derivative function of a spectral reflectance curve has a maximum volue or the second- order differential derivative function shows 0) of a spectral reflectance curve obtained by measuring the spectral reflectance of the pigment to 600-640nm, e.g. a cosmetic containing this pigment gives a spectral reflectance curve having a hollow in a wavelength region of 500-620nm. The healthy skin gives a spectral reflectance curve having a hollow at a wavelength of 500-620nm, whereas the darkish skin gives a spectral curve having a shallow hollow at 500-620nm. Therefore, the compound oxide in an amount to give a concentration of 5wt.% is mixed with a body pigment to obtain a red pigment which gives a spectral reflectance curve having a hollow at 500-620nm.
