Additional information
Conclusion on classification
The toxicity of ‘diallyl 2,2'-oxydiethyl dicarbonate’to aquatic organisms (all three trophic levels) has been studied according to a number of reliable guideline methods under GLP and non-GLP conditions. The results of these studies indicate that ‘diallyl 2,2'-oxydiethyl dicarbonate’ is considered as very toxic to aquatic organisms, based on the lowest EC/LC50 value derived (fish, LC50(96h) 0.57 mg/L) in an acute toxicity test. Chronic data on fish revelaed an NOEC >= 1,06 mg/L for fish, thus no classification for chronic aquatic toxicity is warranted. The substance is in addition deemed readily biodegradable.
The substance is classified as H400 "Very toxic to aquatic life" according to Regulation (EC) No 1272/2008.
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).
