Conclusion of the opinion:

1. In light of the data provided, does the SCCS consider Titanium Dioxide (nano) safe when used as UV-Filter in sunscreens and personal care spray products at a concentration up to 5.5%?

From analysis of the submitted dossier, the SCCS has concluded that the information provided is insufficient to allow assessment of the safety of the use of nano-TiO2 in spray applications that could lead to exposure of the consumer’s lungs.

The dossier provides exposure studies that have been conducted with water-based sprayable products with low alcohol content, which according to the market overview currently represent around 80% of the sprayable sunscreen products on the EU market. For the non-water-based formulations or formulations that contain alcohol >10% per weight, which currently may represent around 20% of the sprayable sunscreen products on the EU market, no exposure data were submitted, so that these could not be evaluated at all. The submission also does not provide adequate toxicological evaluation of nano-TiO2 relevant to the inhalation route, which would allow deriving a point of departure for the safety evaluation using worst-case assumptions. During the commenting period on the preliminary Opinion, the Applicant provided a new submission, the analysis of which (Section 3.3.13) showed that it has also not addressed the SCCS concerns over the safety of titanium dioxide (nano) when used as UV-filter in sunscreen and personal care sprayable products.

2. Does the SCCS have any further scientific concerns regarding the use of Titanium Dioxide (nano) when used as UV-Filter in sunscreens and personal care spray products?

The SCCS has been made aware by the new submission of the Applicant that there are already sprayable products on the market containing nano forms of TiO2. Such uses need to be carefully evaluated so that the chance of harmful effects through consumer's lung exposure by inhalation is avoided.
