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.
