Zusammenfassung:The present invention relates to a cosmetic composition for blocking ultraviolet and blue light, including silica-cerium oxide core-shell fusion particles. Dispersion stability, flowability and spreadability of the powder are improved by preparing cerium oxide as a fusion particle together with silica, and the mixing of Benton gel used as a thickener can effectively block ultraviolet rays and blue light. 본 발명은 실리카-세륨옥사이드 코아-쉘 융복합 입자를 포함하는 자외선 및 블루라이트 차단용 화장료 조성물에 관한 것이다. 세륨옥사이드를 실리카와 함께 융복합 입자로 제조함으로써 분산 안정성 및 파우더 자체의 유동성 및 발림성이 개선되고, 점증제로 사용되는 벤톤 겔을 함께 혼합하면 자외선 및 블루라이트 차단이 더욱 효과적으로 이루어질 수 있다.
