Firstly, TiO2 is commonly used as a white pigment in plastic products. Its high refractive index and ability to scatter light across the visible spectrum provide excellent opacity and brightness to plastic materials. This makes it an essential component in producing white or light-colored plastics, such as packaging materials, household items, and toys. The addition of TiO2 not only enhances the aesthetic appeal of these products but also improves their overall quality by increasing their durability and resistance to UV radiation.

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.
