二氧化钛微粒分散复合粒子及化妆品
摘要：
本发明的二氧化钛微粒分散复合粒子(1)具备二氧化硅粒子(10)和二氧化钛微粒(20)。二氧化钛微粒(20)分散在二氧化硅粒子(10)的内部。二氧化钛微粒(20)为具有2nm～8nm的平均一次粒径的金红石型。本发明的二氧化钛微粒分散复合粒子(1)相对于可见光具有高的透明性。
摘要（英）：

These composite particles (1) in which titanium dioxide microparticles are dispersed are provided with silica particles (10) and titanium dioxide microparticles (20). The titanium dioxide microparticles (20) are dispersed within the silica particles (10). The titanium dioxide microparticles (20) are rutile-type microparticles having an average primary particle diameter of 2-8 nm. These composite particles (1) in which titanium dioxide microparticles have high transparency with respect to visible light.
