Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aquatic toxicity studies of neodecanoic acid, zirconium salt are not available. Read-across to the assessment entities zirconium substances and neodecanoic acid is applied since the ions of neodecanoic acid, zirconium salt determine its fate and toxicity in the environment. Zirconium is poorly soluble and precipitates under most environmental conditions whereas neodecanoate is rather mobile. The potential for acute toxicity of zirconium in the form of zirconium dioxide to aquatic invertebrates is thus low based on the 48h-EC50 above the OECD 202 test limit of 100 mg ZrO2/L for Daphnia magna. Regarding neodecanoate, based on a reliable OECD 202 equivalent study, the 48-h EL50 for D. magna is > 457 mg/L (measured) neodecanoic acid. Thus, neodecanoic acid, zirconium salt has a low potential for acute toxicity to aquatic invertebrates.

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.
