Our scientific experts applied for the first time the 2018 EFSA Scientific Committee Guidance on Nanotechnology to the safety assessment of food additives. Titanium dioxide E 171 contains at most 50% of particles in the nano range (i.e. less than 100 nanometres) to which consumers may be exposed.  

Aside from the attributes we mentioned above, titanium dioxide is known for its durability, which can create a pigment that’s extra long-lasting. On top of that, combined with other colors, titanium dioxide can instantly amplify color by providing intensity and brightness. That has made it particularly popular for foundation and lipstick formulas.
