Safety profile

SCCS reviewed nanoparticulate zinc oxide in opinion SCCS/1518/13 and concluded it is safe at up to 25% in sunscreens but should not be used in spray formulations that could lead to inhalation. Zinc oxide is one of the most stable UV filters and is often recommended for sensitive skin and infant sunscreens.
