Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 under most environmental conditions so that microorganisms in the STP will not be exposed to zirconium. This was confirmed by a standard activated sludge respiration inhibition study with zirconium acetate. No statistically significant toxic effects were observed at all test concentrations employed. The 3-h EC50 and NOEC were determined to be > 1000 mg/L and >= 1000 mg/L anhydrous zirconium acetate, respectively. Regarding the toxicity of neodecanoic acid, an inhibition of nitrification was not observed at the highest test concentration resulting in a NOEC ≥ 100 mg/L neodecanoic acid. Thus, neodecanoic acid, zirconium salt has a low potential for toxicity to microorganisms.

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.
