  • Publication number: 20240156697
    Abstract: An inorganic composite pigment capable of elevating ultraviolet (UV) protection, and a cosmetic composition including the same, in which the inorganic composite pigment includes a core part including a white pigment; and a surface coating material, which is coated on the surface of an external part of the core part, including an inorganic solution that includes the white pigment. Additionally, the white pigment is at least one kind selected from the group consisting of titanium dioxide, zinc oxide, cerium oxide, silica, talc, mica, and borosilicate. The inorganic composite pigment according to the present disclosure capable of elevating a UV protection undergoes surface modification of the pigment through a process of re-coating a white pigment on a white pigment with a high refractive index, thereby elevating the UV protection.
