Additional information

Conclusion on classification

Classification related key information for AES (C12-14, 1-2.5 EO) TEA (CAS 157627-94-6)

 

Readily biodegradable: 78-100% (ThCO2) in 28 days (OECD 301B)

Low potential for bioaccumulation based on log Kow

 

Acute toxicity:

- For fish: 96 h LC50 (Danio rerio) = 7.1 mg a.i./L (nominal, OECD 203)

- For invertebrates: 48 h EC50 (Daphnia magna, immobilization) = 7.4 mg a.i./L (nominal, OECD 202)

- For algae: 72 h EC50 (Scenedesmus subspicatus, growth rate) = 14 mg a.i./L (nominal, OECD 201)

 

Chronic toxicity:

- For fish: 28 d NOEC (Oncorhynchus mykiss; mortality and sublethal effects) = 0.14 mg/L (measured, similar to OECD 215)

- For invertebrates: 21 d NOEC (Daphnia magna, reproduction): = 0.27 mg a.i./L (measured, OECD 211)

- For algae: 72h NOEC (Scenedesmus subspicatus, growth rate) = 0.95 mg a.i./L (measured, OECD 201)

 

Classification justification according to CLP of AES (C12-14, 1-2.5 EO) TEA (CAS 157627-94-6):

Based on the data above, AES (C12-14, 1-2.5 EO) TEA is considered to be rapidly degradable and has a low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 are above 1 mg/L for fish, invertebrates and algae. Valid chronic toxicity data are available to fish, invertebrates and algae – the lowest NOEC is 0.14 mg/L (thus in the range of > 0.1 to < 1 mg/L). AES (C12-14, 1-2.5 EO) TEA needs to be classified and labeled as environmental hazard Chronic Cat. 3 according to the Regulation (EC) No.1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (7th ATP).
