- no
- Remarks:
- not applicable; model application
- Statistical methods:
- not applicable; model application
- Preliminary study:
- Rate constants cannot be estimated
- Test performance:
- not applicable; model application
- Transformation products:
- not specified
- Details on hydrolysis and appearance of transformation product(s):
- not applicable; model application
- Other kinetic parameters:
- not applicable; model application
- Details on results:
- Rate constants cannot be estimated
- Validity criteria fulfilled:
- not applicable
- Remarks:
- no study required
- Conclusions:
- Alcohols are stable and do not hydrolyze in water
- Executive summary:
Hydrolysis rate constants cannot be estimated for isononanol with EPI Win. This is reasonable because the hydrolysis of an alcohol, i.e. the reaction with water at the C atom bearing the OH-group, would result in the very same alcohol. Therefore, isononanol is stable in water.

Additional information
Hydrolysis rate constants cannot be estimated for isononanol with EPI Win. This is reasonable because the hydrolysis of an alcohol, i.e. the reaction with water at the C atom bearing the OH-group, would result in the very same alcohol. Therefore, isononanol is stable in water.
