PURPOSE:To obtain an aerosol cosmetic, having ultraviolet ray shielding effects, excellent dispersibility in a formulated concentrate and stability for a long period without reaction with a solvent, by blending a colloidal solution of silica- treated titanium oxide having a specific particle diameter with a propellant. CONSTITUTION:An aerosol cosmetic obtained by blending a colloidal solution prepared by dispersing silica-treated titanium oxide having <=60mum maximum particle diameter and >=5-<30mum average particle diameter in water or an alcohol or polyhydric alcohol, such as glycol or glycerol, with a propellant. Dimethyl ether, CFC gas, such as dichlorofluoromethane or trichloromonofluoromethane, liquefied petroleum gas, such as propane or butane, and compressed gas, such as CO2 gas or N2, are cited as the propellant. The amount thereof blended is 2-95wt.%. The amount of the aforementioned colloi dal solution of silica-treated titanium oxide is 0.001-30wt.% expressed in terms of titanium oxide (as TiO2) based on the total weight. |
