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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Results and discussion
- Details on results:
- Ammonium carbonate at 5, 10, 25, or 50 mg ammonium ion/l decreased the fertility of Daphnia magna, at 50 mg ammonium ion/l disrupted embryonic development, and at 10, 25, or 50 mg ammonium ion/l impaired postembryonic growth of the crustacea.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- In the test conditions, diammonium carbonate induced decreases in the fertility of Daphnia magna, disruption of embryonic development, and impaired postembryonic growth. However the precise endpoint and concentrations are not indicated. Moreover, effect of ammonia relased during decomposition in water may be the toxic agent. not the substance itself. therefore these data cannot be used to derivate a classification.
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.
