Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

TFAH reacts violently with water and is instantaneously degraded in TFA, which is the relevant substance for risk assessment and classification & labelling purposes. However, the pH of the substance is naturally low and for testing under realistic environmentally conditions either the sodium salt (NaTFA) or pH adjustment are required.

One study is available, as a weight of evidence approach, to assess the adsorption potential of NaTFA. This study was carried out according to OECD guideline 106 with three soil types. The TFA-anion poorly adsorbs to the different soil components because after 16 hours of agitating in a soil/water system less than 3% of the initial amount of TFA had disappeared from the water phase. Due to the fact that less than 25% is adsorbed, no further testing is required by the OECD guidelines.
