Classification related key information
Water solubility: < 1 mg/L
Degradation:
Biodegradation: 27.5-41.1% in 28 days (OECD 301B)
Bioaccumulation:
No significant bioaccumulation in biota is expected for this substance (see IUCLID section 5.3.1).
Aquatic acute toxicity:
96 h, LC50 (Cyprinus carpio): no effect up to the limit of water solubility
48 h, EL50 (Daphnia magna): no effect up to the limit of water solubility
CLP
Based on the currently available data, Fatty acids, C18 unsaturated, trimers, 2-ethylhexyl esters (CAS No. 173832-46-7) is not considered to be rapidly degradable but is expected to show low bioaccumulation potential. No acute toxic effectswere observed up to the water solubility limit (< 1 mg/L) for fish and daphnids, with EC50 values > 100 mg/L (nominal).. Therefore, Fatty acids, C18 unsaturated, trimers, 2-ethylhexyl esters does not need to be classified and labelled as environmental hazard according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).
DSD
Based on the currently available data, Fatty acids, C18 unsaturated, trimers, 2-ethylhexyl esters (CAS No. 173832-46-7) is not considered to be rapidly degradable but is expected to show low bioaccumulation potential. No acute toxic effects were observed up to the water solubility limit (< 1 mg/L) for fish and daphnids, with EC50 values > 100 mg/L (nominal). Therefore, Fatty acids, C18 unsaturated, trimers, 2-ethylhexyl esters does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
