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 UV resistance are important. Also used in sunscreens and cosmetics for its ability to block ultraviolet radiation without irritating the skin. Found in printing inks, paper, textiles, and ceramics to enhance whiteness, improve coverage, and increase strength and heat resistance. In glass manufacturing, it adds opacity and durability. In some applications, it serves as a photocatalyst in self-cleaning surfaces, air purification systems, and construction materials when exposed to light.
