Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Studies of the aquatic toxicity of zinc 3,5,5-trimethyl hexanoate are not available. Read-across to the assessment entities soluble zinc substances and trimethyl hexanoic acid is applied for the assessment of zinc 3,5,5-trimethyl hexanoate since the ions of zinc 3,5,5-trimethyl hexanoate determine its fate and toxicity in the environment.
Reliable data available for soluble zinc substances and trimethyl hexanoate (or rather its structural analogue neodecanoate) indicate that the moiety of ecotoxicological concern are zinc cations. For zinc cations a NOEC of 0.1 mg Zn/L was derived for nitrification inhibition of microorganisms whereas data for neodecanoic acid point to a low (if any) toxic potential to aquatic microorganisms since an inhibition of nitrification was not observed up to the highest test concentration (NOEC ≥ 200 mg/L).

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.
