Description of key information

The substance is readily biodegradable, therefore hydrolysis can be waived.

A first-order reaction rate Kd of 0.039 +/- 0.008 was calculated for DCM disappearance in samples that were kept in the dark. This corresponds to a half-life of about 1.5 years (Dilling et al.1975 )

DCM is hydrolytically stable.

Key value for chemical safety assessment

Half-life for hydrolysis:
1.5 yr
at the temperature of:
298 K

Additional information

Dichloromethane is not easily hydrolysed under normal environmental conditions. A half life of 1.5 year is reported by Dilling et. al (1975). Other studies - albeit under uncommon environmental conditions - support these findings.
