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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 zinc dipropionate are not available. In the assessment of substance zinc dipropionate, read-across to the assessment entities soluble zinc substances and propionate is conservatively applied since the ions of substance zinc dipropionate 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:
Propionate:
Long-term toxicity testing in aqautic invertebrates has been waived.
Zinc:
Freshwater:
Data on 13 species available. Species NOECs range between 0.037 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)
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.
