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.

Description of key information

Alcohols do not hydrolyze under ambient conditions

Key value for chemical safety assessment

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.
