Widely used as a white pigment in paints, coatings, and plastics due to its high opacity and brightness. Provides excellent UV resistance and weatherability in exterior applications. Common in architectural paints, industrial coatings, and automotive finishes. Used in the paper industry to improve whiteness, opacity, and smoothness, especially in high-quality printing papers and board. A key ingredient in sunscreens and cosmetic products because of its ability to block UV radiation safely and effectively. Found in foundations, powders, and lipsticks for its brightening and opacifying properties. Employed in food products as a color additive (E171) to enhance whiteness, such as in candies, coatings, and some dairy products, though regulatory scrutiny has increased in recent years. Used in photocatalytic applications, including self-cleaning surfaces, air and water purification systems, where it breaks down organic pollutants under UV light. Also utilized in the production of ceramics, glass, and catalysts, and increasingly in nanotechnology and solar cell applications.
