Titanium Dioxide - Safe Cosmetics. Titanium dioxide (TiO2) is used in a variety of personal care products, including sunscreens, pressed powders, and loose powders, as a UV filter or whitening agent. In lotions and creams (dermal exposure), it is not a risk for adverse health effects.
Repeated dose studies showed nano-TiO 2 toxicity at various levels (central nervous system, kidney, spleen and gametes), but the doses used were far higher than those to which humans can be exposed in the context of an incidental oral exposure through cosmetic use.
Despite the widespread consensus on the safety of TiO 2 in cosmetic applications, concerns have recently been raised following the opinion delivered by the European Food Safety Authority (EFSA) in May 2021 on the food grade of TiO 2 called E171, which is also used in cosmetics.
Finally, SCCS provided an Opinion on TiO2 (nano form) coated with Cetyl Phosphate, Manganese Dioxide or Triethoxycaprylylsilane as UV-filter in dermally-applied cosmetics (SCCS/1580/16). The Opinion confirmed previous assessment: safe use in cosmetics for products intended for application on skin.
13 Απρ 2018 · When inhaled, titanium dioxide is considered possibly carcinogenic to humans. This means that in products that contain powdered titanium dioxide like loose powders, pressed powders, eyeshadows, and blushes in which the makeup is in powder form, titanium dioxide can be inhaled.
At the skin level, most studies performed in humans or animals showed that nano-TiO 2 did not penetrate beyond the outer layers of stratum corneum to viable cells and did not reach the general circulation, either in healthy or in compromised skin.
