Description of key information
Hazardous to the aquatic environment - acute
Aquatic Acute toxicity data are not available.
As reported in the C&L inventory (ECHA website) for some Company, the substance is classified as Aquatic Acute 1; however, it is not possible to understand what are the data that support this classification.
Toxicity data predicted by ECOSAR (class Neutral Organics) are below 1 mg/L for all trophic levels.
Data predicted by the model "Fish Acute (LC50) Toxicity classification (SarPy/IRFMN) 1.0.2" indicate that the LC50 for fish is between 1 and 10 mg/l; however, in this model, only moderately similar compounds with known experimental value in the training set have been found.
Overall, available data are inconclusive for the classification of the substance.
Hazardous to the aquatic environment - chronic
Aquatic Chronic toxicity data are not available.
As reported in the C&L inventory (ECHA website) for some Company, the substance is classified as Aquatic Chronic 1; however, it is not possible to understand what are the data that support this classification.
Toxicity data predicted by ECOSAR (class Neutral Organics) are below 1 mg/L for all trophic levels.
Data predicted by the model "Fish Acute (LC50) Toxicity classification (SarPy/IRFMN) 1.0.2" indicate that the LC50 for fish is between 1 and 10 mg/l; however, in this model, only moderately similar compounds with known experimental value in the training set have been found.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
