Conclusion on classification

Degradation

Biodegradation: 62.1% after 28 d (OECD 301B)

 

Bioaccumulation

Expert statement: Bioaccumulation is assumed to be low.  

 

Aquatic acute toxicity

96 h, LL50 (Pimephales promelas): no effect up to the limit of water solubility

48 h, EL50 (Daphnia magna): no effect up to the limit of water solubility

72 h, EL50 (Pseudokirchnerella subcapitata):no effect up to the limit of water solubility

 

Aquatic chronic toxicity

28 d, NOEC (Danio rerio): no effect up to the limit of water solubility, read-across

72 h, NOELR (Pseudokirchnerella subcapitata): no effect up to the limit of water solubility

CLP

Based on the data above, of Fatty acids, C18-unsatd., dimers, 2-ethylhexylesters (CAS No. 68334-05-4) is considered to be rapidly degradable. No acute aquatic toxicity was observed up to the water solubility limit (< 1 mg/L) for fish, algae and daphnids. Valid chronic data are available with no effects up to the limit of the water solubility. Therefore, Fatty acids, C18-unsatd., dimers, 2-ethylhexylesters 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

The substance is poorly soluble in water and no effects occurred up to its solubility limit in acute tests for fish, algae and aquatic invertebrates. Therefore, Fatty acids, C18-unsatd., dimers, 2-ethylhexylesters does not need to be classified and labelled as environmental hazardous according to Directive 67/548/EEC.
