Additional information
Conclusion on classification
Official classification regarding environmental hazards
Aquatic compartment
In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2: no data found.
Self-classification
Aquatic compartment
Following CLP (GHS-EU), the substance is not to be classified as acutely hazardous to the aquatic environment. Based on the available acute and chronic data, the substance is not to be classified as chronically hazardous to the aquatic environment.
Rationale:
- The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is > 1 mg/L.
Chronic data are available only for algae and invertebrates, therefore classification is based on the available chronic and acute toxicity data.
- Chronic toxicity data:
Chronic data are available for algae (72 -h ErC10 = 20.18 mg/L) with the target substance itselfs and invertebrates (21 -d EC10 reproduction = 4.07 mg/L) with structurally similar read-across substance, indicating that the substance does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for rapidly degradable substances.
- Acute toxicity data:
The substance is rapidly degradable, the calculated BCF values are < 500 L/kg (and the measured log Kow is < 4. The acute effect value for fish, the organism not covered by chronic toxicity data, is > 1000 mg/L in freshwater (96 -h LC50). Therefore, no long-term hazard exists based on the categories outlined in Table 4.1.0(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 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).
