Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Additional information

1-Chloro-1,1-difluoroethane is not readily biodegradable in water under aerobic condition (about 5 % of biodegradation after 28 days) (Duphar 1991). No simulation tests are availbale. The rate constant used in the assessment are:

Degradation in STP

 0 d-1

Biodegradation rate in water

 0 d-1


In accordance with column 2 of REACH Annex IX, the sediment and soil simulation tests don't need to be conducted as the substance is a gas and has a low potential for adsorption (log Kow 2.05); it is expected that direct and indirect exposure of soil and sediment is therefore unlikely.
