Another important property of Chinese anatase titanium dioxide is its photocatalytic activity, which enables it to break down organic pollutants and harmful chemicals when exposed to light. This makes it an attractive choice for applications in environmental remediation, such as air and water purification systems. Additionally, its photocatalytic properties have also been studied for use in self-cleaning surfaces, such as windows and building facades, where it can help to reduce maintenance costs and keep surfaces looking clean.

Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
