Conclusion on classification
Aquatic toxicity data is available for two trophic levels (acute daphnia and algal inhibition). In a limit acute daphnia test, no immobilities were observed in the undiluted filtrate of a saturated solution at a loading rate of 100 mg test item/L (equivalent to mean measured concentration of 1.07 mg/L). Therefore it is concluded that the registered substance exhibits no acute toxicity to daphnia at its solubility limit. In the algal inhibition test no concentration-response relationship was observed for the biological parameter growth rate. The %-inhibition seen for the parameter growth rate was <10%. Therefore, the ErC10 and ErC50 were stated to be higher than the highest tested concentration level (100% of a saturated solution at a loading rate of 100 mg/L, equivalent to 1.07 mg Amberketal/L). Thus based on growth rate, Amberketal was considered to exhibit no biologically significant effect up to its solubility limit.
Based on the above information the substance does not exhibit any acute toxicity up to its solubility. Therefore no acute classification applies. However, since the substance is not readily biodegradable and has a log Kow of >4, the "safety net" classification of Category Chronic 4 is applicable.
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.
