摘要：
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 μm.
