Conclusion on classification
Environmental official classification according to Annex VI of Regulation (EC) No 1272/2008 of the European Parliament and of the Council of 16 December 2008: Trifluoroacetic acid is reported under the Index No 607-091-00-1 and is classified as Aquatic Chronic 3, H412.
This official classification is conservative because, based on the key studies available, the substance should not be classified for the environment as explained below :
Short-term E/LC50 values are available for algae (key study growth rate 72hEC50 = 237 mg/L), daphnia (48hEC50 > 100 mg/L) and fish (96hLC50 > 100 mg/L). All of the key studies demonstrate E/LC50 above 100 mg/L, showing that the substance does not need to be classified for acute toxicity to aquatic organisms according to the CLP and the UN-GHS criteria.
Additionally, trifluoroacetic acid is not readily biodegradable and due to the log Kow < 4 there is no tendency to bioaccumulate. Chronic toxicity data are available for algae showing a 72hErC10 of 5.6 mg/L, for daphnia showing a 21dNOEC above 25 mg/L and for fish showing a 35d NOEC above 3.8 mg/L. Therefore, the substance does not need to be classified for chronic toxicity to aquatic organisms according to the CLP and UN-GHS criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
