Description of key information
2-propylheptylacrylate is considered to be readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
To assess the potential of the test substance to biodegrade, results of a GLP study carried out with non-adapted domestic sludge were available. The test procedures followed OECD guideline 301 B. In this test a degradation rate of 60 - 70% after 28 days was reported, but the 10 -day window was failed [BASF 2008].
The test substance is a mixture composed of the two isomers 2-propylheptylacrylate and 4 -methyl-2 -propylhexylacrylate. In such a case, the 10-day window should not be applied to interpret the results, since it is anticipated, that depending on structural properties the isomers have different biodegradation kinetics. Therefore 2 -propylheptylacrylate is considered to be readily biodegradable irrespective of the 10 -day window criterion was not being fulfilled for the mixture.
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.
