Abstract: The present invention relates to a method for producing titanium dioxide powder having a silica-treated surface. The titanium dioxide powder produced by the method consists of particles, each of which has a diameter larger than 100 nm, and therefore removes concerns about harmful effects on the human body, which have been known as being caused by nanoscale particles. The titanium dioxide powder produced by the method has the ability of blocking ultraviolet rays over a wide range consisting of the ultraviolet A region as well as the ultraviolet B region. Further, the titanium dioxide powder produced by the method is provided with significantly improved feeling of use as compared to conventional nanoscale ultrafine titanium dioxide powder, and therefore can be effectively used in ultraviolet-blocking cosmetics.
