Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
The lowest acute LC50 for fish, 51 mg/L, was observed for the effect of octanoic acid (C8) in a reliable, GLP-conform 96 h toxicity test with Oryzias latipes conducted similar to OECD 203. However, results should be considered carefully due to the decrease of solution pH observed with increasing test concentrations. The observed pH decrease may provoke weakness in fish and a higher sensibility.
Zinc:
Key data (lowest LC50 values) are:
-for Oncorhynchus mykiss: 0.169 mg Zn/L (single value) at neutral/high pH and low hardness
-for Pimephales promelas (single values): 0.780 mg Zn/L at low pH (high hardness) and 0.330 mg Zn/l at neutral/high pH, high hardness
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.
