Description of key information
Measured bioconcentration factors (BCF) for the substance Fatty acids, tall-oil, reaction products with formaldehyde and (Z)-N-9 -octadecenyl-1,3 -propanediamine are not available.
The bioaccumulation potential (BCF) of Fatty acids, tall-oil, reaction products with formaldehyde and (Z)-N-9-octadecenyl-1,3-propanediamine (CAS# 68911-83-1) was estimated to be 6.17 L/kg wet weight according to the BCFBAF v3.01 model of EPIWIN v.4.10. This result is based on the estimated log Kow of 13.8.
Measured Kow values (Brekelmans, 2013) are available for the substance. The HPLC method appplied revealed more than 50 compounds to which a Pow value could be attributed. The Kow values were in the range of 3 to >6.5 (pH 2) and 1.4 to >6.5 (pH 10) at 20 °C, with a vast majority (89% at pH 2 and 76% at pH 10) showing a log Pow >6.5. The test was performed at pH 2 and 10 as there is not one specific pH at which all groups will be in their non-ionized form. When choosing a log Pow of 6.5 (the highest measured), the model estimated a BCF of 381 L/kg wet-wt for the substance. The estimated BCF according to the Arnot-Gobas BCF method for the upper trophic was estimated to be 586 L/kg wet-wt.
A calculated BCF value should only be used for assessment in the absence of experimental data as a rough estimation.
It can be concluded that in this case, the calculated BCF values are far away from the criterion of BCF>2000 (B) and BCF>5000 (vB) indicating that the substance has no significant bioaccumulation potential. The measured low water solubility of this compound (unbound value of < 1 mg/L) (Brekelmans, 2013) also demonstrates that the substance is most likely not bioavailable to aquatic organisms. Therefore the B and vB criterion is not fulfilled.
A BCF value of 381 L/kg ww was calculated as a worst case key value for use in case exposure calculations are needed for secondary poisoning (aquatic foodchain) or man via the environment.
