The main concern with nanoparticles is that they are so tiny that they are absorbed into the skin more than we want them (ideally sunscreen should remain on the surface of the skin). Once absorbed they might form unwanted complexes with proteins and they might promote the formation of evil free radicals. But do not panic, these are concerns under investigation. A 2009 review article about the safety of nanoparticles summarizes this, to date, in-vivo and in-vitro studies have not demonstrated percutaneous penetration of nanosized particles in titanium dioxide and zinc oxide sunscreens. The English translation is, so far it looks like sunscreens with nanoparticles do stay on the surface of the skin where they should be.

In the context of titanium dioxide determination, the process generally begins with the sample preparation, where a known mass of the sample containing TiO2 is dissolved or digested appropriately. The subsequent steps involve adding a precipitating agent, such as ammonium sulfate or sulfuric acid, to the prepared solution, which facilitates the formation of a titanium precipitate. This precipitate is often titanium hydroxide, which is not only insoluble but can be easily filtered out from the liquid phase.

In conclusion, the determination of barium as TiO2 in industrial factories requires a combination of analytical techniques depending on the specific requirements of the application. Each method has its own advantages and limitations, and the choice of technique should be based on factors such as accuracy, precision, cost, and turnaround time. With the proper selection and implementation of these techniques, manufacturers can ensure the quality and safety of their products while complying with environmental regulations.
