The European Chemicals Agency (ECHA; Helsinki, Finland) says new classification and labelling requirements for titanium dioxide (TiO2) are coming into force 1 October, following EU Commission’s Delegated Regulation 2020/217. The substance must be classified as carcinogen if inhaled (Carc. 2, H351 inhalation) when supplied on its own or in mixtures, where the substance or mixture contains 1% or more of TiO2 particles with an aerodynamic diameter ≤10μm, ECHA says.
In addition, mixtures containing TiO2 must be labelled with the supplemental label element ‘Hazardous respirable dust may be formed when used. Do not breathe dust’ (EUH212), according to the new requirements. Non-classified solid mixtures must also be labelled with the EUH212 supplemental labelling element if they contain at least 1% of TiO2, regardless of their form, or particle size, ECHA says.
Liquid mixtures containing TiO2 do not require Carc. 2 classification, ECHA says. However, if they contain at least 1% of TiO2 particles with an aerodynamic diameter ≤10μm, then they need to be labelled with the supplemental label element ‘Hazardous respirable droplets may be formed when sprayed. Do not breathe spray or mist’ (EUH211), it says.
