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.

Administrative data

biodegradation in water: simulation testing on ultimate degradation in surface water
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable
Justification for type of information:
Docosonaic acid has been shown to decompose rapidly (see 5.2).  Fatty acids in general are considered readily biodegradable (see e.g. stearic acid and oleic acid). In accordance with column 2 of EC 1907/2006 Annex IX 9.2 further testing is not required as the chemical safety assessment according to Annex I does not indicate the need to investigate further the degradation of the substance and its degradation products.
