Q
why is titanium dioxide used
Engineer Life: To inspire and educate future engineers in my journey of understanding the industrial world.
Titanium dioxide (TiO2) is widely used due to its unique properties, such as high refractive index, strong UV light absorption, and resistance to discoloration under ultraviolet light. These characteristics make it an ideal pigment in paints and coatings, providing whiteness and opacity. Additionally, it's used in the food industry as a coloring agent (E171), in sunscreens for UV protection, and in various cosmetic products for its ability to scatter light, improving the appearance by making the complexion appear brighter. Its inert nature also means it doesn't readily react with other substances, making it safe for use in food and cosmetic applications. However, its safety, especially in nano form, has been subject to regulatory review and ongoing research to ensure consumer safety.
