Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
None of the available acute aquatic toxicity data on the free acid indicates a hazard LC50<100mg/L. From the three trophic levels for which median acute concentrations could be determined, fish have the lowest (limited effects on algae were observed up to the highest concentration tested). Because no information on biodegradability is available, the substance should not be classified R52/53. Similarly, R53 should not be applied due to the lack of information on biodegradability, and an estimated water solubility of >8300mg/L. As a result, there is insufficient evidence to classify the substance for environmental hazards, according to the criterial laid out in Directive 2001/59/EC, Annex VI, 5.2. This classification is considered to be inconclusive.
None of the available acute aquatic toxicity data on the free acid indicates a hazard LC50<100mg/L. From the three trophic levels for which median acute concentrations could be determined, fish have the lowest (limited effects on algae were observed up to the highest concentration tested). Chronic Category 3 should not be applied due to the lack of information on biodegradability, the partition coefficient is logPow<4, and a long-term fish NOEC>1mg/L is available for the sodium salt analogue. As a result, there is insufficient evidence to classify the substance for environmental hazards, according to the criteria laid out in Regulation (EC) No. 1272/2008, Annex I, Part 4, 4.1.2. This classification is considered to be inconclusive.
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.
