Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
One reliable study is available for C14 AO. In this study, performed according to OECD TG 202, groups of 5 Daphnia magna per concentration were exposed to C14 AO under static conditions for 48 hours at nominal test concentrations of 0, 5, 9, 16.2, 29.2 or 52.5 mg/L (equivalent to 0, 1.19, 2.13, 3.84, 6.92 or 12.44 mg AO/L). The 48-h EC50 based on nominal concentrations was 2.64 mg AO/L [Mark UE and Garttener-Arends ICM (1994)].
Data are available also for C12-14 AO. These data may be used to support the findings of the study performed using C14 AO alone as the substance contains a significant amount of C14 AO and the remainder comprises an analogue substance with very similar chain length.
Three reliable studies performed using Daphnia magna are available for C12-14 AO. All three studies were performed to OECD TG 202 under static conditions. The EC50 (48h) values (nominal) obtained were 3.1 mg AO/L [Noack M (2001)], 2.9 mg AO/L [Mark U & Meuwsen IJB (1990)] and 4.2 mg AO/L [Beneventi S (2005)].
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.
