Subject: New Approved Coatings for Titanium Dioxide (nano)

Dear All,

The nano form of Titanium Dioxide is used in cosmetic products as a UV filter and this use is regulated via the European Cosmetics Regulation (Annex VI, Entry 27a).

One of the use conditions is the coating of Titanium Dioxide with one of these materials: Silica, Hydrated Silica, Alumina, Aluminium Hydroxide, Aluminium Stearate, Stearic Acid, Trimethoxycaprylylsilane, Glycerin, Dimethicone, Hydrogen Dimethicone, Simethicone.

With Regulation EU No 2019/1857, the European Commission approved three new coatings for Titanium Dioxide (nano), namely:

  • Silica at a maximum concentration of 16 % and Cetyl Phosphate at a maximum concentration of 6 %
  • Alumina at a maximum concentration of 7 % and Manganese Dioxide at a maximum concentration of 0.7 % (not to be used in lip products)
  • Alumina at a maximum concentration of 3 % and Triethoxycaprylylsilane at a maximum concentration of 9 %

The combination “Alumina at a maximum concentration of 7 % and Manganese Dioxide at a maximum concentration of 0.7 %” is toxic by ingestion. Therefore, the legal warning “Not to be used on the lips” shall be displayed on the product labels each time this specific coating is used and regardless of the product category.

We hope that this letter will provide you with helpful information.

Best regards,
Dr. Fred Lebreux
