Additional information
Conclusion on classification
Self-classification according to REGULATION (EC) No 1272/2008 (CLP):
The substance is not to be classified for acute aquatic hazards since the acute toxicity is >10 to <=100 mg/L.
From acute toxicity data, no chronic hazard category does result because the substance is readily biodegradable and does not bioaccumulate significantly (experimentally determined BCF <= 500).
The only available chronic ecotoxicity data are from the study on freshwater green algae, for which an EC10 (72 h; growth rate) of 45 mg/L had been determined. This value is above the limit for readily degradable substances given in REGULATION (EC) No 1272/2008. Accordingly, no chronic hazard category does result from available long-term data.
Overall, according to REGULATION (EC) No 1272/2008 there are no classification requirements for environmental hazard.
Self-classification according to UN-GHS ST/SG/AC.10/30 /Rev.7 (2017)
Because of E(L)C50-Values between 10 and 100 mg/L, the following acute toxicity classification applies:
o Aquatic Acute 3
o H402: Harmful to aquatic life.
For chronic aquatic toxicity, no classification is applicable (see EU-GHS above for details).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
