Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Key value for chemical safety assessment
Additional information
Experimental data investigating the bioaccumulation potential of
Amides, C18, branched and linear are not available. The substance
components are characterised by a log Pow > 5 indicating a potential to
bioaccumulate in biota. However, the information gathered on
environmental behaviour and metabolism in combination with the
QSAR-estimated BCF values provide enough evidence to state that the
substances is not likely to bioaccumulate. The substance is insoluble in
water (water solubility < 0.05 mg/L). The Guidance on information
requirements and chemical safety assessment, Chapter R.7b, states that
once insoluble chemicals enter a standard STP, they will be extensively
removed in the primary settling tank and fat trap and thus, only limited
amounts will get in contact with activated sludge organisms (ECHA,
2014). Therefore, after passing through conventional STPs, only low
concentrations of these substances are likely to be (if at all) released
into the environment.
Thus, the most relevant exposure route for aquatic organisms such as
fish will be via food ingestion or contact with suspended solids. If the
substance is ingested by organisms enzymatic hydrolysis to fatty acids
and ammonia is expected (see IUCLID section 7.1.1). Fatty acids are an
important energy source for many organisms. A significant accumulation
of the substances in organisms is therefore not anticipated.
The conclusion is further supported by estimated bioconcentration (BCF)
and bioaccumulation (BAF) values calculated for the iso and linear
component of the substance (BCFBAF v3.01 program, Estimation Programs
Interface Suite™ for Microsoft® Windows v 4.10., US EPA). The
calculation assumes biotransformation (Arnot-Gobas method). The BCF
values estimated for the iso and linear component range from 146.3 –
151.2 L/kg. The range of the calculated BAF values is 159 – 170.5 L/kg.
