Additional information
Conclusion on classification
Based on read-across from the structurally similar substance, the available data on aquatic toxicity do not meet the classification criteria according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.
Degradation
Biodegradation: not readily biodegradable (14% after 28 d, OECD 301B)
Bioaccumulation
Expert statement: Bioaccumulation is assumed to be low.
Aquatic acute toxicity
96 h, LL50 (Oncorhynchus mykiss) > 100 mg/L (nominal), (read across), no observed toxicological effects up to the water solubility limit (< 0.15 mg/L)
48 h, EL50 (Daphnia magna) > 100 mg/L (nominal), (read across), no observed toxicological effects up to the water solubility limit (< 0.05 mg/L)
72 h, EL50 (Scenedesmus subspicatus) > 100 mg/L, (read across), no observed toxicological effects up to the water solubility limit (< 0.05 mg/L)
CLP:
Based on the data above, for Dipentaerythritol hexaesters of 3,5,5 -trimethylhexanoic and n-heptanoic acids (EC 945 -883 -1, CAS 1379424 -11 -9) no acute aquatic toxicity was observed up to the water solubility limit (< 0.05 mg/L) for fish, algae and aquatic invertebrates.
Therefore, fatty acids C5-10 esters with dipentaerythritol does not meet the criteria for classification and labelling as environmental hazard according to the Regulation (EC) No 1272/2008 and the Regulation (EU) No 286/2011 (6th ATP).
