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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Endpoint:
- hydrolysis
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is readily biodegradable
- Justification for type of information:
- In accordance with Column 2 of REACH Annex VIII, information requirement section 9.2.2.1, this study does not need to be conducted if the substance is readily biodegradable. The test material contains no nitrogen therefore the evaluation of biodegradation has to be based ThODNH4. The criterion for ready biodegradability under the conditions of a manometric respirometry test is the 10-day window, describing the period between reaching at least 10 % degradation and 60 % degradation. The mean biodegradation after 28 days of the test material was 85 % (ThODNH4); the 10-day window criterion was passed from day 8 to day 18. Test data have therefore shown that the test material is readily biodegradable and as such testing is not required.

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.
