A cosmetic water-in-oil composition is provided which includes a water-in-oil emulsifying silicone surfactant, an ultrafine titanium dioxide and conjugated linoleic acid. The presence of conjugated linoleic acid stabilizes the composition against color degradation and also maintains an approximately steady viscosity.
