Additional information
PNECs were calculated in line with the Guidance on information requirements and chemical safety assessment Chapters R.10 and R.16.
Data on the substance were limited to acute ecotoxicity studies across three trophic levels (fish, daphnia and algae). The PNEC STP was calculated from the toxicity values seen in the ready biodegradability study. A Koc value of 259,000 was calculated using EUSES from data on the substance's physico chemical properties and has been used for the derivation of PNECs concerning sediment and soil..
Conclusion on classification
In accordance with teh criteria set out in section 4.1.2.6 (Table 4.1.0) of Regulation (EC) No 1272/2008 (CLP), the substance is classified as hazardous to the aquatic environment, Chronic Category 2.
This is based on the lowest L(E)C50 value from the available acute ecotoxicity studies (daphnia EC50 = 4.5 mg/L) and the substnace's physico chemical properties log Kow >4 (in the absence of any bioaccumulation data).
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).
