Widely used as a white pigment in paints, coatings, and plastics due to its high refractive index and excellent light-scattering properties. Provides brightness and opacity, making it ideal for architectural paints, industrial coatings, and exterior applications where durability and weather resistance are important. Also used in sunscreens and cosmetics for its ability to block ultraviolet radiation safely and effectively. Found in printing inks, paper, and textiles to enhance whiteness and improve coverage. Additionally, employed in some photocatalytic applications and self-cleaning surfaces due to its stability under UV light.
