Hydrolysis
Administrative data
Link to relevant study record(s)
- 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
Reference
Description of key information
According to structural properties, hydrolysis is not expected. In addition, the substance is readily biodegradable therefore no experimental study needs to be conducted.
Key value for chemical safety assessment
Additional information
According to REACH Annex VIII, column 2 a study on hydrolysis is not necessary if the compound is readily biodegradable. The test item is classified to be ready biodegradable.
The test item undergoes, essentially complete hydration to yield the gem-diol, methylene glycol (Kumar, 1986). Equilibrium almost totally favours the glycol; less than 0.04% by weight of unhydrated test item is found in highly concentrated solutions (WHO, 2002; Environment Canada, 2001). Furthermore, the substance is readily biodegradable. Therefore, no hydrolysis testing is required for registration under REACH.
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.
