Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
In the assessment of calcium neodecanoate, read-across to the assessment entities soluble calcium substances and neodecanoic acid is applied since the ions of calcium neodecanoate determine its fate and toxicity in the environment. The potential for chronic toxicity of calcium to aquatic invertebrates is very low, further supported by the fact that calcium is added to standard test media. According to the QSAR-based outcome of the model ECOSAR (EPI Suite 4.0), neodecanoic acid has a low potential for chronic toxicity to aquatic invertebrates since the chronic value for daphnids (ChV = 10^([log (LOEC x NOEC)]/2)) was estimated with 1.7 mg/L. Also, a 21 -d NOEC of 4.78 mg/L (reproduction) was determined in a chronic toxicity test with Daphnia magna and neoheptanoic acid (a structural analogue of neodecanoate). In sum, the potential of calcium neodecanoate for chronic toxicity to aquatic invertebrates is assumed to be low.

Additional information
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.
