About

One of the most widely used and thoroughly researched cosmetic ingredients, titanium dioxide serves as a white pigment and UV-filtering agent with an excellent safety record in non-nano cosmetic formulations.

Titanium dioxide (CAS 13463-67-7, CI 77891) is approved as a colorant (Annex IV) and UV filter (Annex VI) under EU Regulation 1223/2009. The SCCS has assessed titanium dioxide as safe for cosmetic use in non-nano form at concentrations up to 25% in UV filters. Nano-form titanium dioxide used as UV filter requires specific declaration and is subject to additional SCCS restrictions regarding primary particle size and coating. Titanium dioxide is considered one of the safest and most inert cosmetic ingredients, with no evidence of skin sensitisation or systemic toxicity from topical application.

Skin benefits

  • UV protection (approved EU filter)
  • White pigment/opacifying agent
  • Photostable and inert
  • Suitable for sensitive skin

Known concerns

  • Nano-form UV filter has additional regulatory requirements in EU
  • Inhalation risk when used in spray/powder formulations (IARC carcinogenicity by inhalation)
