Additional information
Conclusion on classification
In accordance with Regulation (EC) No 1272/2008 (CLP) the following environmental classification applies to the substance: Environmental Hazard Aquatic Chronic 1 (H410)
Short-term and chronic aquatic toxicity data is available for all three trophic levels (daphnia, algae and fish):
1. No effects up to the solubility limit in the
test media were observed in the fish acute (2004) and algal inhibition
(2004) study while only 25% immobilisation was observed in the acute
daphnia (2004) study. Since the EC50/LC50 values are greater than the
solubility limit of 1.3 to 1.9mg/L, no acute classification applies.
2. The lowest chronic aquatic NOEC is 0.0043mg/L from a fish ELS study
(2010), which for a non-rapidly degradable substance leads to GHS
Aquatic Chronic 1 (H410) classification. In accordance with Table 4.1.3
of the EU CLP regulations, in order to classify a mixture containing the
substance an M-factor of 10 should be used (0.001 < NOEC ≤ 0.0mg/L;
non-rapidly degradable).
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).
