Titanium dioxide can be coated using a process called sol-gel, commonly used in the production of thin films and fibers. In this method, a solution of titanium alkoxide precursor is prepared, followed by hydrolysis and polycondensation reactions to form a gel. This gel is then applied on the substrate and subjected to high temperature annealing to form the titanium dioxide layer. Factors such as the precursor concentration, hydrolysis ratio, and annealing temperature can all affect the quality of the resulting titanium dioxide coating. Expert supervision and appropriate control of all these factors during the coating process will ensure high-quality results.

As a result of its unique light refraction and absorption properties. titanium dioxide is widely used in sunscreen. sunscreen. and other products due to its composition. At room temperature. titanium dioxide is solid and white. making it suitable for white paints and cosmetics. It is also a major ingredient in mineral cosmetics.

Titanium dioxide is generally considered a safe ingredient in many products like sunscreens or food additives. However, it could pose potential health risks when inhaled in excessive amounts, potentially leading to respiratory tract irritation and damage. It's also classified by the International Agency for Research on Cancer as potentially carcinogenic to humans when inhaled. Long-term exposure can potentially increase the risk of chronic respiratory disease. Despite these risks, the Food and Drug Administration (FDA) considers it safe when used in appropriate amounts. It is advised to use products containing titanium dioxide responsibly and cautiously.
