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.

The demand for TiO2 has been steadily increasing over the years, driven by the growth of the paint and coatings industry, as well as the expansion of its use in other applications such as electronics and cosmetics. In addition, the increasing awareness of the environmental impact of traditional production methods has led to a growing interest in more sustainable production techniques, such as the use of bio-based feedstocks or the implementation of closed-loop processes.
