Additional information
No experimental data are available for RAV 7MC (EC 700-742-1). For justification of the intended read-across approach of Diallyl-2,2 ´-oxydiethyl dicarbonate (EC 205 -528 -7) to Reaction mass of 2,2'-oxydiethanol and 2,2-dimethylpropane-1,3-diol and diallyl 2,2'-oxydiethyl dicarbonate and diallyl carbonate and pentaerythritol' (EC 700 -742 -1), please refer to the overall summary of aquatic toxicity test results.
This endpoint is filled from data from one study in Selenastrum capricornutum (freshwater algae) (Maziarz, 1983a) and another in Skeletonema costatum (saltwater algae) (Maziarz,1983b). The no observable effect concentration (NOEC) for 'diallyl 2,2'-oxydiethyl dicarbonate' in Selenastrum capricornutum is 10 mg/L and in Skeletonema costatum 10µL/L (=11.48 mg/L).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.
