Frequently Asked Questions
Answers in plain language
Is titanium dioxide banned in Europe?
Banned as a food additive (E171) since 2022, but NOT banned in cosmetics. It is permitted as a UV filter (Annex VI) and as a colorant (Annex IV, CI 77891) under Regulation (EC) 1223/2009. The SCCS has reviewed it extensively, including the inhalation risk for spray products and powder cosmetics. Use of pigmentary (non-nano) titanium dioxide in leave-on cosmetic products at standard concentrations is considered safe.
What are the side effects of titanium dioxide?
Mostly limited to a white cast on skin in sunscreens and concealers. Concerns about inhalation of titanium dioxide nanoparticles led the SCCS to advise caution for spray and aerosol cosmetic formats. Direct skin application of pigmentary titanium dioxide is considered safe by EU regulators.
