摘要： The present invention provides products comprising cocoon-shaped rutile-type titanium dioxide, i.e., cosmetics which have high UV blocking ability, provide a good feel upon use without leaving squeakiness or graininess on the skin, and also give a natural bare skin appearance without causing white masking, due to adequate tinting strength and covering power, as well as external additives for toner which are excellent in prevention of filming on a photosensitive member and inhibition of aggregation between toner particles. The present invention is directed to rutile-type titanium dioxide having a cocoon-shape, as well as cosmetics comprising this titanium dioxide, and external additives for toner comprising this titanium dioxide which is hydrophobically treated.
