Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification
Short-term fish and daphnia toxicity studies are available with substances representative of the main constituents and an algae toxicity study is available with the test substance. No acute toxicity was found in the three trophic levels and the L(E)C50 values were established at the highest tested or soluble concentrations (nominal and/or measured). Given the UVCB nature of the test substance with variable solubilities for individual constituents, the nominal values were considered for hazard/risk assessment. The (L)EC50 values were established as >100 mg/L (nominal) for all three trophic levels. According to the EU CLP criteria (Regulation 1272/2008/EC), this effect concentration does not warrant an acute classification. Further, the substance is readily biodegradable its log Kow <4 together with predicted BCF values ranging from 0.89 to 591 L/kg ww (using BCFBAF v3.02 model of EPISuite v.4.11), indicates a lack of bioaccumulation potential. Nevertheless, considering the UVCB nature of the substance along with the existing uncertainties due to and the lack of direct acute data on the test substance for fish and daphnia, a safety net Chronic 4 aquatic classification can be assigned according to EU CLP criteria (Regulation 1272/2008/EC).
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).
