Key value for chemical safety assessment
Additional information
According to Annex XI of regulation (EC) 1907/2006, testing for a specific endpoint may be omitted if testing does not appear to be scientifically necessary or if it is technically not possible to conduct the study as a consequence of the properties of the substance. Hydrolytic degradation is not expected for 1,1 -DPE as aromatic hydrocarbon due to the lack of functional groups.
This is supported by the hydrolysis test result with Phenyl-tolyl-ethyne.
Therefore no further testing is justified.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.
