Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
hydrolysis
Type of information:
calculation (if not (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:
The hydrolysis is based on SPARC-calculations.
Qualifier:
no guideline followed
Principles of method if other than guideline:
Hydrolysis is calculated by the SPARC model.
Estimation method (if used):
The hydrolysis is calculated by SPARC.

Key result
pH:
9
Temp.:
25 °C
DT50:
ca. 31 d
Type:
(pseudo-)first order (= half-life)
Validity criteria fulfilled:
not applicable
Conclusions:
The substance is not expected to hydrolyse at acid and neutral conditions (half-life >>1 yr). Some hydrolysis (DT50 = 31d, at pH=9) may take place at alkaline conditions.
Executive summary:

The hydrolysis half-lives at pH=4, 7, 9 have been calculated by SPARC. The substance is not expected to hydrolyse at acid and neutral conditions (half-life >>1 yr). Some hydrolysis (DT50 = 31d, at pH=9) may take place at alkaline conditions.

Description of key information

The hydrolysis half-lives at pH=4, 7, 9 have been calculated by SPARC. The substance is not expected to hydrolyse at acid and neutral conditions (half-life >>1 yr). Some hydrolysis (DT50 = 31d, at pH=9) may take place at alkaline conditions.

Key value for chemical safety assessment
