Conclusion on classification
Short-term aquatic toxicity data are available for two trophic levels (aquatic invertebrates and aquatic algae). The acute effect value, EC50 for Daphnia is 0.33 mg/L and the ErC50 for Algae >0.31 mg/L. Based on Daphnia with an EC50 value of <1.0 mg/L, the substance needs to be classified for acute aquatic hazard, Category Acute 1, H400: Very toxic to aquatic life (CLP 2008, and its amendments: Table 4.1.0 (a)).
As there are no adequate chronic toxicity data available, acute toxicity data needs to be assessed for long term aquatic toxicity in combination with biodegradability and/or log Kow (CLP 2008, and its amendments: Figure 4.1.1. and Table 4.1.0(b)iii). In view of the substance having a log Kow of 6.6, despite being readily biodegradable, and acute Daphnia toxicity data of < 1 mg/l (0.33 mg/l), the substance needs to be classified as Category Chronic 1 according to Table 4.1.0(b)iii. Therefore for long-term aquatic hazard, the substance is classified as Category Chronic 1, H410: Very toxic to aquatic life with long lasting effects, according to Regulation 1272/2008/EC (CLP) and its amendments.
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.
