Sunscreen producers and UV filter manufacturers are currently
facing urgent challenges. On the one hand, the legal situation
of two widely used UVB filters Ethylhexyl Methoxycinanamte
(EHMC) and Octocrylene (OCR) is unclear due to rising
concerns on their safety for humans and the environment;
on the other hand, the image of nano particulate UV filters
is downgraded in the press and by digital apps questioning
their safety profile without scientifically based evidence. Some
producers pro-actively remove these UV filters from their new
sunscreens’ developments which is a real challenge in terms of
performance achievement. This paper aims to provide UV filter
system alternatives for developing efficient sunscreens without
EHMC and OCR. Additionally, it clarifies the safety situation
of nano-particulate UV filters and explains their usefulness in
sunscreens, providing, however, UV filter system alternatives.
Furthermore, this manuscript presents a calculation method to
assess the impact of a UV filter combination on the environment
and shows that it is possible to develop eco-sustainable
sunscreens. Though, each restriction in the choice of UV filters
will imply certain compromises.
