Description of key information

Based on the high estimated Koc value, 'oils, vegetable, deodorizer distillates’ is expected to adsorb to suspended solids and sediment. However, due to low water solubility and ready biodegradation potential of the substance together with the low estimated BCF values of the constituents (ranging from 3.85-660 L/kg), the bioavailability as well as bioaccumulation in sediment organisms will be limited. Also, similar to mammals, the major constituents (i.e. glycerides and fatty acids) of the substance are known to be metabolised in fish and used as an essential energy source for growth and reproduction (Tocher, 2003).

Considering the above information together with the overall low toxicity potential of the substance in aquatic organisms and mammals (see section 7.1, 7.2.1 and 5 respectively), no toxicity to soil organisms or terrestrial environment is expected. This is further supported by the absence of toxicity observed in a 14 -d acute earthworm toxicity study conducted with a read-across substance 'glycerides, C14 -18 and C16 -18 -unsatd. mono-, di- and tri-‘ which has similar chain length distribution as the glyceride constituent of the test substance. Therefore no further testing is considered to be required, in accordance with Annex IX, Section 9, Column 2 of the REACH legislation. Nevertheless, as described in Chapter 7.6, PNEC sediment has been derived using the Equilibrium Partition Method to conduct a risk assessment for the sediment compartment.
