The harmonised classification (CLH) of some substances, or the revision of their existing classification, will be legally applied from 1 March 2018 onwards.
The Registry of Intentions (RoI), which contains information on substances intended for harmonised classification and labelling (CLH), identification as substances of very high concern (SVHCs) or restriction, has been restructured.
Dodecamethylcyclohexasiloxane (D6) has been added, on request of the European Commission, to the intention that was originally submitted on 13 April 2017 for octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5).
