Description of key information
Additional information
One experimental study equivalent to ISO 10708 confirmed that Fatty acids, C16-18, tetraesters with 3,3'-oxybis[1,2-propanediol] (CAS 91050-80-5) is readily biodegradable (94% biodegradation after 28 d). Therefore, the substance will not be persistent in the environment and ultimately degraded in sewage treatment plants (STPs). The degradation via abiotic hydrolysis is not considered to be a relevant degradation pathway in the environment since reliable QSAR results using HYDROWIN v2.00 resulted in DT50 > 24 h at pH 7. Considering the low water solubility (< 0.05 mg/L) and the high potential for adsorption to organic soil and sediment particles (log Koc > 5, KOCWIN v2.00), the main compartments for environmental distribution is expected to be soil and sediment. However, due to its ready biodegradability, the substance will not persist in these compartments. Evaporation into air and the transport through the atmospheric compartment is not expected since Fatty acids, C16-18, tetraesters with 3,3'-oxybis[1,2-propanediol] is not volatile based on the low estimated vapour pressure (< 0.0001 Pa at 20 °C). However, if released into air, the substance is susceptible to rapid indirect photodegradation by OH-radicals with a DT50 of 1.99 – 5.99 h (AOPWIN v1.92). The potential for bioaccumulation of Fatty acids, C16-18, tetraesters with 3,3'-oxybis[1,2-propanediol] is assumed to be low, based on data on metabolism and QSAR calculations with BCFBAF v3.01
