Sunscreen composition containing surface-modified cerium oxide particles |
| abstract |
The present invention provides a sunscreen composition comprising cerium oxide (CeO2) particles that are surface-modified with silicone, wherein the silicone is methicone, a methicone derivative, or an alkyl silane. The sunscreen composition according to an embodiment of the present invention is easy to be prepared into a formulation applicable to cosmetics and may have a high physical ultraviolet protection effect to block ultraviolet rays in a wide range of wavelengths with an excellent sun protection factor (SPF). In addition, the sunscreen composition according to an embodiment of the present invention has a skin-like color in view of the color tone of the composition and does not cause white cast even when applied to the skin, and thus the composition can be effectively used in producing cosmetics for UV protection that aim to express natural color. |
