Additional information
Since no studies are available on the biodegradability of Fatty acids, C8-10, 2-methylbutyl esters (CAS No. 1365095-43-7), the assessment was based on a study conducted with the structurally most similar category member, for which data is available, isopenthyl laurate (CAS No. 6309-51-9) as part of a read-across approach. This is in accordance with Regulation (EC) No 1907/2006, Annex XI, 1.5. Grouping of substance and read across approach. Further justification is given within the endpoint summary 5 and within the category justification section 13. In this case of read-across, the best suited (highest degree of structural similarity, nearest physico-chemical properties) read-across substance was entered into IUCLID. Isopenthyl laurate contains the same alcohol as Fatty acids, C8-10, 2-methylbutyl esters. The fatty acid moiety is longer, and is therefore expected to be less easily degraded. Since isopentyl laurate is readily biodegradable, Fatty acids, C8-10, 2-methylbutyl esters is expected to be readily biodegradable as well. Furthermore, as can be seen in the data matrix of the category justification in Section 13, all reliable data in the category support the hazard assessment for this endpoint, by showing a consistent pattern of results.
This key ready biodegradability study was carried out with isopenthyl laurate (CAS No. 6309-51-9), following OECD Guideline 301 B and according to GLP (Junghans, 2008). Non-adapted domestic activated sludge was used as inoculum. During the 28-day test period, biodegradation reached 100%, based on CO2 evolution, and the 10-day window criterion was met.
Thus, based on theabove mentioned result, and due to the structural and profile similarities of the substances, as are explained with in the overall endpoint summary 5 it can be concluded that Fatty acids, C8-10, 2-methylbutyl esters (CAS No. 1365095-43-7) can be considered readily biodegradable according to OECD criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
