Additional information
Conclusion on classification
Brief description of the data relevant for classification
Degradation
Biodegradation: Readily biodegradable: 82% in 28 d (CO2 evolution, OECD 301 B)
Bioaccumulation
Expert statement: Bioaccumulation is expected to be low.
Aquatic acute toxicity
For fish: LC50 (96 h) 13 mg/L (nominal)
For aquatic invertebrates: EC50 (48 h) 420 mg/L (nominal)
For algae/aquatic plants: ErC50 (72 h) 37.6 mg/L (measured arithmetic mean)
Aquatic chronic toxicity
For fish: no data available
For aquatic invertebrates: no data available
For algae/aquatic plant: ErC10 (72 h) 13.3 mg/L (measured arithmetic mean)
Conclusion on classification
Based on the data above, Bis(2-(2-butoxyethoxy)ethyl) adipate (CAS 141-17-3) is considered to be rapidly degradable and has a low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 values are > 1 mg/L for fish, aquatic invertebrates and algae. Chronic toxicity data are available for algae with an ErC10 (72 h) of 13.3 mg/L. Thus, the substance does not need to be classified and labelled for aquatic toxicity according to the consolidated version of Regulation (EC) No 1272/2008 (CLP) and all further amendments (ATPs).
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).
