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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Dissociation constant
Administrative data
- Endpoint:
- dissociation constant
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is hydrolytically unstable (half-life less than 12 hours)
- the study does not need to be conducted because the analytical method is not sensitive enough
- Justification for type of information:
- After a testing time of 25 hours, the test-item concentration had increased significantly (i.e. 22% and 26%) at all pHs. Based on the monitored component, the test item did obviously not degrade hydrolytically. Accordingly Tier 2 testing was discontinued. The concentration of the investigated component may have increased as a higher-molecular-weight component degraded. It was, however, not possible to validate an analytical method for such a higher-molecular-weight component with sufficient sensitivity.

Applicant's summary and conclusion
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.
