Description of key information
The Guanidine ion is relevant for the environmental risks resulting from exposure to the substance. To determine whether the manufacture and use of the substance is safe for the environment, without the Koc of Guanidine, a dual worst case approach as explained in RIVM report: http://www.rivm.nl/bibliotheek/rapporten/601516013.pdf will be followed. The environmental risks will be determined by using a Koc value of 10 and by using a Koc value of 1000. These Koc values are determined by RIVM to be the worst case Koc values for the environmental risk assessment. RIVM concludes that in case this approach cannot show safe use, a Batch Equilibrium study is needed.
Key value for chemical safety assessment
Additional information
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.
