Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

hydrolysis
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Justification for type of information:
In the absence of experimental abiotic degradation data, the hydrolysis of the test substance was estimated by using the QSAR HYDROWIN v2.00 (U.S. EPA, 2000), which is recommended by ECHA.
Qualifier:
no guideline followed
Principles of method if other than guideline:
Hydrolysis was determined by using a QSAR (HYDROWIN v2.00 EPI SUITE 2000 U.S. EPA, recommended by ECHA.

Description of key information

The hydrolysis constant and half-lives of this test substance was estimated by a QSAR method (HYDROWIN v2.00 EPI SUITE U.S. EPA, 2000).

At pH 8 and 25°C, the calculated half-life value was of 13.243 years. At pH 7, the calculated half-life was of 132.432 years. Although these predictions result from QSAR calculations, there is evidence that the test substance is not rapidly hydrolysable.

Key value for chemical safety assessment

Half-life for hydrolysis:
