The bioaccumulation potential of Fatty acids, C18-unsatd., dimers, reaction products with fatty acids, C14-18 and C16-18-unsatd. and propylidynemethanol (CAS 162353-70-0) is expected to be very low. Though the partition coefficient of the substance (log Pow > 10) indicates a potential to accumulate the bioavailability of the substance is expected to be low. This conclusion is based on the ready biodegradability, low water solubility and rapid metabolisation of the substance. Furthermore bioconcentration and bioaccumulation factors (BCF/BAF) calculated for the single substance components indicate a low potential of the substance to accumulate in organisms (BCF/BAF: 0.893 L/kg).
Therefore, in accordance with Annex IX of Regulation (EC) No 1907/2006 the bioaccumulation potential is considered low.
