Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

For the reaction massof potassium trifluoroacetate and potassium trifluoromethanesulphinate reliable short-term toxicity data are available for three trophic levels. Based on the results, it was not possible to determine short-term E/LC50 values because they are above the highest tested concentrations: algae (growth rate 72hEC50 > 100 mg/L), daphnia (48hEC50 > 128 mg/L) and fish (96hLC50 > 122 mg/L). In accordance with Regulation (EC) No 1272/2008, Table 4.1.0 (a), classification for acute aquatic hazard is not required for the reaction massof potassium trifluoromethanesulphinate and potassium trifluoroacetate as all EC50/LC50 values are above the classification criterion of 1 mg/L.

Additionally, the Reaction mass of potassium trifluoroacetate and potassium trifluoromethanesulphinate is not readily biodegradable and has a low potential for bioaccumulation (Log Kow < 1).

Long-term toxicity data are available for three trophic levels and the results show critical effect values of 10 mg/L (35d NOEC, Fish), 3.21 mg/L (21d NOEC, Daphnia) and 2.26 mg/L (72h EC10, Algae). In accordance with Regulation (EC) No 1272/2008, Table 4.1.0 (b) (i), the Reaction mass of potassium trifluoroacetate and potassium trifluoromethanesulphinate is not classified for long lasting effects to the aquatic environment since the lowest chronic NOEC value exceeds the classification criterion of 1.0 mg/L
