Dermal Absorption of Nanomaterials Titanium Dioxide and Zinc Oxide Based Sunscreen
Role of Size and Surface Coating ,Environmental project No. 1736, 2015 Editing: Christiane Beer, Department of Public Health, Aarhus University, Denmark
Summary:
In this project, sunscrren containing nano TiO2 was tested using in vitro and in vivo mouse and human skin models. Dermal penetration of TiO2 and ZnO NPs did not occur at or above the limit of detection of the used experimental methods. This is in accordance with the conclusions that were made by the EU Scientific Committee on Consumer Safety that stated that both kind of nanoparticles are safe to use for dermal applications up to a concentration of 25% in cosmetic products [SCCS (Scientific Committee on Consumer Safety), 2012; SCCS (Scientific Committee on Consumer Safety), 2014].
