Background

Titanium Dioxide, TiO2, (CAS/EC numbers 13463-67-7/236-675-5, 1317-70-0/215-280-1, 1317-80-2/215-282-2) is authorized both as colorant under entry 143 of Annex IV, as UV-filter under entry 27 of Annex VI, and in powder form in entry 321 of Annex III to Regulation (EC) No.1223/2009.

In July 2013, the Scientific Committee on Consumer Safety (SCCS) issued the safety evaluation on Titanium Dioxide (nano) concluding that the use of Titanium Dioxide (nano) as UV-filter, at concentrations up to 25% and with the characteristics indicated in the Opinion, can be considered not to pose any risk of adverse effects in humans after application on healthy, intact or sunburnt skin. Among the characteristics reported in that Opinion, the SCCS indicated the substances considered safe for use as coating for TiO2 (nano). Regarding the use of other coatings, not covered in the Opinion, the SCCS concluded that:
“Other cosmetic ingredients applied as stable coatings on TiO2 nanomaterials can also be used, provided that they can be demonstrated to the SCCS to be safe and the coatings do not affect the particle properties related to behaviour and/or effects, compared to the nanomaterials covered in this Opinion.”

The SCCS conclusion clarifies that for the use of a substance as …
