Description of key information
Additional information
Experimental data on the environmental fate of Fatty acids, C8 -10, octyl esters (CAS 91031-98-0) are available. Therefore, in accordance to Regulation (EC) No. 1907/2006 Annex XI, 1.5 Grouping of substances, read-across to octyl octanoate (CAS 2306-88-9) was conducted. Fatty acids, C8 -10, octyl estersis an UVCB substance comprising linear C8-10 fatty acids esterified with octanol.The source substance,linear C8 fatty acid esterified with octanol, is a main component of the target substance and thus both substances are characterised by a similar environmental fate. The assessment of relevant properties of the target substance determining fate and pathways in the environment is based on QSAR calculations. The calcuations were performed with the main components of the target substance octyl octanoate (CAS 2306-88-9) and decyl octanoate (CAS 2306-89-0).
Partitioning of a substance into the different environmental compartments depends mainly on its physico-chemical properties. Since Fatty acids, C8-10, octyl esters is poorly soluble in water, not volatile, and have high adsorption potential, it is not expected to be found in the air or water compartments. If released in surface waters, the substance would probably partition from the water phase to the sediment. Based on physico-chemical properties, the main target compartments for the substance would thus be soil and sediment. However, Fatty acids, C8 -10, octyl esters is considered to be readily biodegradable and highly sorptive and are thus expected to be eliminated in sewage treatment plants to a high extent. Release to surface waters, and subsequent exposure of sediment, is therefore very unlikely. Accumulation into organisms is not expected, since the substance can be digested by common metabolic pathways, as dietary fats (e.g., Berg et al. 2002, Mattson and Volpenheim 1972, Tocher 2003).
The fate of Fatty acids, C8-10, octyl esters is also influenced by (bio-)chemical processes it may undergo in the environment. Due to its ability to rapidly biodegrade the substance is also expected to be rapidly eliminated within the environment. However, hydrolysis and photodegradation is not considered to be a relevant degradation pathway, since the substance is not expected to be present in the water and air compartments. In conclusion, Fatty acids, C8 -10, octyl esters (CAS 91031-90-0) is expected to be found mainly in soil and sediment, where the substance will be rapidly degraded by microorganisms.
