Description of key information

In accordance to REACH (EC) No 1907/2006, Annex IX, section 9.3.2, column 2, a study on bioaccumulation can be waived if no direct or indirect exposure to the environment is expected. At production sites, the esters are handled in closed systems for polymerisation. Diffuse releases into the environment from residual monomers in the polymeric products are not of concern due to the extremely low vapour pressure of the substances. Thus no test is required.
The bioaccumulation potential of 2 -Propenoic acid, docosyl esters was calculated to be 35.27 L/kg or log BCF = 1.547 using the EPA Epiwin (v.4.11) software. According to Annex XIII a substance does not fulfils the Bioaccumulation criterion (B-) when the bioconcentration factor (BCF) is lower than 2000, therefore a test for bioaccumulation: aquatic/sediment does not need to be conducted.
