Conclusion on classification

The environmental classification of C12-18 AAAO is currently not harmonised according to the CLP Regulation (EC) 1272/2008.


Acute toxicity data is available for the three trophic levels (fish, invertebrates, and algae). The lowest valid effect concentration for freshwater aquatic organisms is 0.68 mg/L (96h-LC50 for fish). Based on the available acute data, the substance should be classified for acute toxicity (Aquatic Acute 1, M=1).


Chronic toxicity data is available for invertebrates and algae. The lowest valid effect concentration is 0.303 mg/L (72h-NOErC for algae). The substance is readily biodegradable; its log Kow is < 4. Based on this available data, the substance should be classified for chronic toxicity (Aquatic Chronic 3).
