摘要：
The present invention relates to a composite pigment coated with titanium dioxide, a method for producing the same, and a cosmetic composition containing the same. The method comprises the steps of: firstly processing a surface by hydrolyzing a titanium dioxide precursor titanium tetrachloride (TiCl_4) with a pigment to have a uniform coating surface secondly processing a surface by hydrolyzing a titanium dioxide precursor titanium tetrachloride (TiCl_4) with the firstly surface-processed pigment and by agitating the same after hydrolysis is finished, so as to have a non-uniform coating surface and completing a composite pigment coated with titanium dioxide (TiO_2) by converting TiO(OH)_2 into TiO_2 by plasticizing the secondly surface-processed pigment. A luminant inorganic composite pigment according to the present invention has brilliance of 30-35 which is lower than brilliance of 40-50 of a nacreous pigment, and a shielding force (haze value) is 70-80 which is higher than 50-60 of a nacreous pigment. Accordingly, the luminant inorganic composite pigment of the present invention can have a dim luminant effect and a shielding force which are suitable to skin.COPYRIGHT KIPO 2017본 발명은 이산화티탄이 코팅된 복합안료 및 그 제조방법, 및 이를 함유한 화장료에 관한 것으로, 안료에 이산화티탄 전구체 사염화티탄(TiCl4)을 가수분해 반응시켜 균일한 코팅표면을 갖도록 1차 표면처리 하는 단계 1차 표면처리된 안료에 이산화티탄 전구체 사염화티탄(TiCl4)을 가수분해 반응시키되 반응종료 후 교반시켜 불균일한 코팅표면을 갖도록 2차 표면처리 하는 단계 2차 표면처리된 안료를 소성처리하여 TiO(OH)2를 TiO2로 전환함에 의해 이산화티탄(TiO2)이 코팅된 복합안료 완성단계를 포함하여 제조되며, 본 발명에 따른 광채 무기 복합안료는 광택도가 30~35로 일반 진주광택안료가 갖는 광택도 40~45 보다 낮으며, 은폐력(HAZE 값)은 70~80으로 일반진주 광택안료의 50~60보다 높으므로, 피부에 적합한 은은한 광채 효과 및 은폐력을 얻을 수 있는 효과가 있다.
