Description of key information
Sodium caprolactamate hydrolyses immediately in contact with water with
the formation of sodium hydroxide and epsilon-Caprolactam.
epsilon-Caprolactam is not considered to hydrolyze rapidly when released
to water.
Key value for chemical safety assessment
Additional information
The half-life of epsilon-Caprolactam in water was calculated to be > 1 a (with HYDROWIN v1.67). Hydrolysis is not expected to be an important environmental fate process due to its slow hydrolysis rate.
The half-life of sodium caprolactamate cannot be determined due to the spontaneous reaction with water.
