Additional information
In accordance with REACH Regulation, Art. 3, and ECHA "Guidance for identification and naming of substances under REACH and CLP" v1.2, March 2012, substances have to be separated from solvents if this is not affecting the stability of the substance or changing its composition.
In this case, separation of water would only be possible by thermical damaging of the substance. Furthermore, it was not possible to spray dry the pigment solution as it stuck to and partly melted on the conus dryer.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
