Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
The available experimental test data and read-across data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008.
Calcium dioctanoate has a lowest EC50 of 1.60 mg/L for growth rate of aquatic algae based on geometric mean measured concentrations (Dickinson, 2018). The lowest EC10 is 0.223 mg/L for growth rate of algae, based on geometric mean measured concentrations, from the same study. Calcium dioctanoate is considered to be readily biodegradable based on read-across (Kim et al 2001 and Gerike and Fischer 1979) and has a log Kow of <1.
Based on these results, the substance is not classified for acute aquatic toxicity as it has a lowest EC50 >1 mg/L.
As chronic data is not available, chronic environmental classification has been assessed based on acute data only. Based on acute data the substance is not classified (EC50 >1 mg/L, readily biodegradable and log Kow <4).
Based on these results, the substance is not classified for chronic aquatic toxicity.
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.
