Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to REACH Regulation (EC) No 1907/2006 Annex IX section 9.3.2 column 2 a study for bioaccumulation in aquatic species, preferably fish need not be conducted if no direct or indirect exposure to the aquatic 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. Direct and indirect exposure of the test item to water is highly unlikely. Thus no test is required.
In the supporting study to 2-Propenoic acid, C22 alkyl ester the bioaccumulation potential of the test substance was calculated to be 1.613/(35.27) L/kg or log BCF = 0.119 and for 2 -Propenoic acid, C18 alkyl ester BCF = 10.95/(323.6) or logBCF 1.040. 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 to 2-Propenoic acid, C18 -22-alkyl esters does not need to be conducted.

Additional information
QSAR-disclaimer
In Article 13 of Regulation (EC) No 1907/2006, it is laid down that information on intrinsic properties of substances may be generated by means other than tests, provided that the conditions set out in Annex XI (of the same Regulation) are met. Furthermore according to Article 25 of the same Regulation testing on vertebrate animals shall be undertaken only as a last resort.
According to Annex XI of Regulation (EC) No 1907/2006 (Q)SAR results can be used if (1) the scientific validity of the (Q)SAR model has been established, (2) the substance falls within the applicability domain of the (Q)SAR model, (3) the results are adequate for the purpose of classification and labeling and/or risk assessment and (4) adequate and reliable documentation of the applied method is provided.
For the assessment of dodecyl acrylate and tetradecyl acrylate(Q)SAR results were used for assessment of bioaccumulation.The criteria listed in Annex XI of Regulation (EC) No 1907/2006 are considered to be adequately fulfilled and therefore the endpoint(s) sufficiently covered and suitable for risk assessment.
Further experimental studies on bioaccumulationare not provided.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
