Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

1,1,1,2 -tetrafluoroethane (HFC 134a) is a gas of low solubility and is expected to quickly disappear from the aquatic phase. Therfore, any impact on the aquatic environment is expected to be low.

Key value for chemical safety assessment

Additional information

1,1,1,2 -tetrafluoroethane (HFC 134a) is a gas of low solubility and is expected to quickly disappear from the aquatic phase. Therfore, any impact on the aquatic environment is expected to be low. These mitigating factors indicate that aquatic toxicity is unlikely to occur, and a long-term toxicity study on aquatic invertebrates will be inappropriate in accordance with REACH Annex IX 9.1 Column 2.
