Additional information
Conclusion on classification
Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae). The acute effect values for fish (D.rerio), daphnids and algae (P. subcapitata) are 12.4 mg/L, 15 mg/L and 26 mg/L, respectively. The substance does not need to be classified for acute aquatic hazard. Long-term aquatic toxicity data are available only for aquatic algae for which a ErC10 of 12 mg/L was determined. As only one reliable long-term toxicity endpoint is available, chronic classification needs to be based on both acute and chronic data and the worst case classification applied. The substance is readily biodegradable, has a log Kow of 4.5 (no experimental BCF is available) and a lowest acute effect value in the range of 10-100 mg/L based on which it shall be classified as chronic 3 (H412). Based on its ready biodegradability and the chronic effect value of >1 mg/L no chronic classification is required. Therefore, based on the acute toxicity data, the substance is classified as Aquatic Chronic 3 (H412) according to Regulation 1272/2008/EC (CLP).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
