Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Octanoic acid, zinc salt, basic:
Toxicity studies of octanoic acid, zinc salt, basic are not available. In the assessment of environmental toxicity of octanoic acid, zinc salt, basic, read-across to the assessment entities soluble zinc substances and octanoic acid is applied since zinc cations and octanoate anions determine its fate and toxicity in the environment.
Octanoic acid:
In a reliable, GLP-conform chronic toxicity test with Daphnia magna according to OECD 211, a 21 d NOEC of 0.2 mg/L was determined for the effect of decanoic acid (C10) on the reproduction of Daphnia magna.
Zinc:
Freshwater: Data on 13 species available. Species NOECs range between 0.014 and 0.400 mg Zn/l (dissolved concentrations)
Marine: Data on 26 species available. Species NOECs range between 0.0056 and 0.9 mg Zn/l (dissolved concentrations)
Respective NOEC/EC10 values were applied in the species sensitivity distribution.
Key value for chemical safety assessment
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.
