Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Biodegradation
Biodegradation in water: screening test (Weight of Evidence approach)
2-Propenoic acid, C16-18-alkyl esters (read across)
In the Ready Biodegradability (CO2-Evolution) Test the degree of biodegradation of the test substance at the end of exposure was determined to be 50-60 % CO2/ThCO2.
Dodecyl acrylate (C12) (read across)
The degree of biodegradation of the test substance was 80-90 %CO2/ThCO2 after an exposure period of 28 days.The read across substance (mixture of CAS no. 2156-97-0 and 21643-42-5) is readily biodegradable under the conditions of this test.
Icosyl acrylate (C20) (read across)
The degree of biodegradation of the test substance was 60-70 %CO2/ThCO2 after an exposure period of 60 days.The test item was biodegradable under the enhanced test conditions of this test.
2 -Propylheptyl acrylate is considered to be readily biodegradable (60 -70%).
2 -ethylhexyl acrylate is readily biodegradable according to OECD criteria (70 -80%).
Conclusion
Considering the results of the biodegradation studies with Dodecyl acrylate/ Laurylacrylate (C12), 2-Propenoic acid, C16-18-alkyl esters.
Biodegradation in water and sediment: simulations test
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex IX, section 9.2.1.2 and section 9.2.1.4, no study on biodegradation in water and sediment needs to be conducted if the test substance is biodegradable under test conditions. The long-chain alkylsters (C12 - C14) are all readily biodegradable under test conditions. Thus no futher biodegradation testing in water and sediment is required.
Biodegradation in soil
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex IX, section 9.2.1.3, no study on biodegradation in soil needs to be conducted if the test substance is biodegradable under test conditions. The long-chain alkylsters (C12 - C14) are all readily biodegradable under test conditions. Thus no futher biodegradation testing in soil is required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
