Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
This endpoint is filled from data from an acute toxicity test of the test substance 'Reaction mass of bis[2-(2-{[(prop-2-en-1-yloxy) carbonyl]oxy}ethoxy) ethyl] carbonate and diallyl 2,2'-oxydiethyl dicarbonate' (EC 700-483-4) to Rainbow Trout (Oncorhynchus mykiss), investigated according to OECD 203 / EU Method C.1. Juvenile Rainbow Trout were exposed in a static test to aqueous test media containing the test item at various concentrations under defined conditions. The concentrations of the test item were verified by analysis. The recorded effects were mortality and sublethal effects. The 96 hour LC50 was determined to be 1.362 mg/L. The No Observed Effect Concentration (NOEC) was determined to be 1.1 mg/L and the Lowest Observed Effect Concentration (LOEC) was determined to be 2.0 mg/L, whereby all values are based on nominal concentrations.
Additionally supporting data from 'diallyl 2,2'oxydiethyl dicarbonate' (CAS 142-22-3) from two adequate fish toxicity tests (Sousa, 1982; Ward,1982b) are available. The 96 hours LC50 values for freshwater (Lapomis macrochirus) and saltwater (Cyprinodon variegatus) fish are 0.57 mg/L and 0.707 mg/L, respectively. For justification of this read-across approach, please refer to the overall summary of aquatic toxicity test results.
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.
