Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Fatty acids, C16-18, zinc salts:
Long-term toxicity studies on aquatic invertebrates of fatty acids, C16-18, zinc salts are not available. Thus, read-across to the assessment entities soluble zinc substances and C16-18 fatty acids is applied since zinc cations and fatty acid anions (C16-18) determine fate and toxicity in the environment. Since C16 -18 fatty acids have a low potential for ecotoxicity, the hazard assessment of fatty acids, C16-18, zinc salt is based on zinc ions. Please refer to the endpoint summary of the respective assessment entity for further details.
Fatty acid anions (C16-18):
Fatty acids as contained in plant and animal tissue are a natural component of aquatic systems, represent a significant part of the nutritional demands of living organisms, are rapidly degraded and non-bioaccumulative and have a low potential for chronic toxicity to aquatic invertebrates.
Zinc:
The NOEC values for 13 freshwater species range from 0.014 to 0.400 mg Zn/L and for 26 marine species from 0.0056 and 0.9 mg Zn/L (all dissolved).

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.
