Description of key information
EC50 (48h) > 100 mg/l on aquatic invertebrates
EC50 (72h) > 100 mg/l on aquatic algae
Additional information
Justification for classification
According to the CLP Regulation (EC 1272/2008), the threshold of classification of a substance for acute aquatic toxicity is 1 mg/l. This limit is compared with LC50 (96h) for fish, EC50 (48 h) for daphnia and EC50 (72 - 96 h) for algae.
Test substance was found to be soluble and stable in test medium under test conditions. In a ready biodegradability assay, the substance resulted as ready biodegradable.
In short term studies on daphnia and algae, no effects were seen at the highest tested concentrations, thus EC50 > 100 mg/l for both species. Based on these results, no classification for acute toxicity is applied.
No chronic toxicity data was available from long-term studies.
In case of lack of chronic data, a decision on classification is based on acute toxicity data, potential of degradability and potential of bioaccumulation.
In particular, substances for which adequate chronic toxicity data are not available, are classified in:
- category chronic 1, when E(L)C50 < 1 mg/l
- category chronic 2, when E(L)C50 between 1 and 10 mg/l
- category chronic 3, when E(L)C50 between 10 and 100 mg/l
and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log Pow ≥ 4).
The substance is readily biodegradable, thus lowering its potential toxicity to organisms upon chronic exposure; moreover, EC50 value for both aquatic invertebrates and algae are above 100 mg/l and logPow is < 4.
On these bases, no classification for chronic aquatic toxicity is applied according to the CLP Regulation (EC 1272/2008).
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).
