Titanium oxide, also known as titanium dioxide (TiO2), is a white, opaque mineral commonly used as a pigment in paints, coatings, and plastics. It is valued for its brightness and high refractive index, which helps to enhance the color and opacity of products. Additionally, it is used in sunscreens due to its ability to block ultraviolet (UV) light. In nature, titanium oxide occurs in several forms, including rutile and anatase. It is non-toxic and environmentally friendly, making it a popular choice in various applications. Beyond cosmetics and coatings, titanium oxide is also utilized in photocatalysis and as a catalyst in chemical reactions.
