Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 with substance Fatty acids, C18-24, zinc salts are not available. In the assessment of substance Fatty acids, C18-24, zinc salts, read-across to the assessment entities soluble zinc substances and fatty acids, C18-24 is conservatively applied since the ions of substance Fatty acids, C18-24, zinc salts determine its fate and toxicity in the environment. The aquatic hazard assessment is based on the most toxic moiety, i.e. the zinc cation.
Please refer to the section for the respective assessment entity for data on the moieties. In brief:
ZINC key data:
Freshwater:
Data on 7 species available. Species NOECs range between 0.044 and 0.530 mg Zn/L (dissolved concentrations)
Marine:
Data on 1 species available. NOEC = 0.025 mg Zn/L (dissolved concentrations)
FATTY ACIDS, C18-24:
The ecotoxic potential of the fatty acid chain, i.e. fatty acids, C18-24, is assumed to be negligible. Fatty acids are generally not considered to represent a risk to the environment, which is reflected in their exclusion from REACH registration requirements (c.f. REACH Annex V (Regulation (EC) No 987/2008)).
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.
