And/or does the SCCS have any further scientific concern with regard to the use of zinc oxide in cosmetic products? ZnO is also used as a colorant in cosmetic products. In view of the similar toxicity of both nano-sized and fine ZnO, it is considered that ZnO is safe when used as colorant in cosmetics for dermal application.
Titanium Dioxide does not protect from UVB rays in the same way zinc does. The biggest concern with nano particles in cosmetics is the threat of inhalation when they are used in zinc oxide powder and sprays. This is not a concern with zinc because it is put in a lotion or balm. The environmental organization highly recommends a NANO based product over a chemical one for this reason. Why is zinc so effective …

Nanoparticles in Sunscreens. Zinc oxide offers good protection from UVA rays. Titanium oxide's protection isn't as strong, but it's better than most other active ingredients. Nanoparticles in American sunscreens are either titanium dioxide or zinc oxide. Zinc oxide is EWG's first choice for sun protection.
