Additional information
According to Regulation (EC) No.1907/2006, Annex XI, Section 2, the testing regime may be adapted because testing is technically not feasible as a consequence of the properties of the substance. The dry salt of cyanide has no partition coefficient, as it is no longer in the form of a salt when it is placed in water under normal conditions. Rather, the salt is converted to hydrogen cyanide, which has a partition coefficient of -0.25 at 20 °C.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
