Zusammenfassung:	The present invention relates to a composite powder consisting of titanium dioxide powder and silicone, which are inorganic sunscreens contained in a composition for sunscreen, and to a method for preparing the same. A core-shell type composite powder of the present invention exhibits excellent UV-blocking performance (SPF 50+, PA +++), and at the same time, can avoid the controversy over potential harmful effects of nanoparticles due to the particle diameter with several microns. According to the present invention, by enabling a preparation process to be simplified, it is possible to cost-effectively prepare a composite powder for UV protection. 본 발명은 자외선 차단용 조성물에 포함되는 무기계 자외선 차단제인 이산화티탄 분말과 실리콘으로 이루어진 복합 분말 및 이의 제조 방법에 관한 것으로서, 본 발명의 코어-쉘 형태의 복합 분말은 우수한 자외선 차단성능(SPF 50+, PA +++)을 나타내면서도 분말의 입자 직경이 수 미크론에 이르기 때문에 나노 입자의 인체 유해성에 대한 논란을 피할 수 있으며, 제조 공정이 단순화되어 비용 효과적으로 제조가 가능한 자외선 차단용 복합 분말 및 이의 제조 방법에 관한 것이다.
