Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The substance TFA is not considered to be a surface-active agent, according to EC criteria.

Key value for chemical safety assessment

Surface tension:
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

A fully reliable GLP study was conducted at the maximum testing concentration of 1 g/L, showing no lowering of the surface tension of water.

A supporting publication indicates that fluorinated compounds exhibit low surface tension; however, as it is only a qualitative information, it may apply to higher concentrations than required for testing.
