Titanium dioxide (TiO2)



In bold, parts of the text that have been modified

1. Does SCCS consider that use of titanium dioxide in its nanoform as an UV-filter in cosmetic products in a concentration up to maximum 25.0% is safe for the consumers taken into account the scientific data provided?

On the basis of the available evidence, the SCCS has concluded that the use of TiO2 nanomaterials with the characteristics as indicated below, at a concentration up to 25% as a UV-filter in sunscreens, can be considered to not pose any risk of adverse effects in humans after application on healthy, intact or sunburnt skin. This, however, does not apply to applications that might lead to inhalation exposure to TiO2 nanoparticles (such as powders or sprayable products). Furthermore, this assessment applies to 13 out of the 15 TiO2 nanoparticles presented in the submission, but may also be applicable to other TiO2 nanomaterials that are similar to the parameters in Tables 1-3, i.e. TiO2 nanomaterials that:
• have TiO2 purity of ≥ 99% , or in case of a lesser purity, the impurities must be demonstrated …
