Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Due to ready biodegradability hydrolysis could be disregarded for the constituent EC 500-029-3. A study on hydrolysis gave that the other constituent of the substance, EC 500-044-5, is hydrolytically stable.
Key value for chemical safety assessment
Additional information
Hydrolysis may adequately described considering study results for both constituents of the substance.
EC 500-029-3
In accordance with Column 2 of REACH Annex VIII, the study does not need to be conducted as the substance is readily biodegradable.
EC 500-044-5
Polyether V531 is found to be stable at 50 °C at all three pH-values. Therefore it can be assumed that the test item is also stable at 25 °C and no half-life times and hydrolysis rates were calculated.
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.
