Commonly found in sunscreen and cosmetics for its ability to block UV radiation without irritating the skin. Employed in paper manufacturing to improve whiteness and opacity. Used in food products as a colorant (E171) to enhance visual appeal, though regulatory scrutiny has increased in some regions. Also utilized in photocatalytic applications, such as self-cleaning surfaces and air purification systems, where it breaks down organic pollutants under light exposure.
