Classification of titanium dioxide

The discussion about titanium dioxide has been intensifying for some time now. From different sources, self-interpretations become loud, which are partly very contradictory. The question of how to deal with the classification of titanium dioxide in powder form is being raised more and more. Since artimelt also uses titanium dioxide in some adhesives, it is important for us to inform our customers and partners about the facts.

In Switzerland, the Globally Harmonized System for the Classification and Labelling of Chemicals (GHS) is based on the European Regulation (EC) No. 1272/2008 (Classification, Labelling, Packaging, CLP Regulation, CLPV). The totally revised Chemicals Ordinance (ChemO, SR 813.11), which came into force on 1 July 2015, refers - as far as possible - directly to the relevant provisions of the CLP Ordinance. The ChemO and the CLPV must therefore be applied together when classifying, labelling and packaging chemicals in Switzerland.

On 4 October 2019, the European Committee for Risk Assessment (RAC) of the European Chemicals Agency (ECHA) has adopted the 14th adaptation to technical progress (ATP) of CLP Regulation No. 1272/2008. This includes the classification of titanium dioxide (TiO2) for classification as carcinogenic category 2 by inhalation (Carc.2; H351i). The European Parliament and the Council of Ministers now have two months to object. The CLP amendment will be published if no objections are raised. The harmonised classifications apply 18 months later.

According to the latest version of the classification proposal, the classification only applies to mixtures in powder form containing 1% or more of titanium dioxide incorporated in the form of aerodynamic diameter particles ≤ 10 µm.

Titanium dioxide finds countless fields of application, which one encounters in everyday life.

artimelt relies on masterbatch instead of powder form
artimelt focuses on sustainability and is committed to increasing the protection of health and the environment. All white artimelt Medical adhesives are pigmented with TiO2, which artimelt uses as a masterbatch. This means that artimelt uses the white pigment in a polymeric carrier and not in powder form. As a result, artimelt employees do not come into contact with powdered titanium dioxide.

Titanium dioxide as a masterbatch, which is used for the production of white pigmented artimelt Medical adhesives. As shown in the picture, this is not a powdery material that can be inhaled.

The white pigmented artimelt products consist of a matrix of different polymeric raw materials in which the titanium dioxide is incorporated - so our customers do not come into contact with powdery titanium dioxide either.
