Description of key information
Additional information
One experimental study according to OECD 301F confirmed that Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters is readily biodegradable according to the OECD criteria (82.2% biodegradation after 28 d). The degradation via abiotic hydrolysis is not considered to be a relevant degradation pathway in the environment since QSAR results using HYDROWIN v2.00 resulted in DT50 values > 100 d at pH 7 and > 18.99 at pH 8. Considering its physico-chemical properties like the low water solubility (4 - 5 mg/L) and the potential for adsorption to organic particles (log Koc: 2.5 - 3.3, KOCWIN v2.00), the substance is expected to partition mainly to the soil and sediment. Nevertheless, persistency in these compartments is not expected since the substance is readily biodegradable and it will be rapidly and ultimately degraded in sewage treatment plants and natural waters. Moreover, adirect exposure to the soil can be excluded based on the identified uses (see IUCLID Section 3.5).Evaporation from the water phase into air and the transport through the atmospheric compartment is not expected to occur in significant amounts for Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters based on the low vapour pressure < 5 Pa at 20 °C. However, if released into air, Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters is susceptible to undergo rapid indirect photodegradation by OH-radicals with a DT50 value of19.55 - 21.06 h(AOPWIN v1.92). Therefore, the potential for accumulation in air and the subsequent transport to other environmental compartments is low. Due to the expected low exposure in the water phase due to rapid environmental biodegradation, the bioavailability and bioaccumulation in aquatic organisms is expected to be low. This is confirmed by low calculated BCF values of 45.78 - 61.6 L/kg ww (BCFBAF v3.01, Arnot-Gobas, including biotransformation, upper trophic). Please refer to IUCLID Section 5.3 for a detailed overview on bioaccumulation of Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters.
