Additional information

The substance Fatty acids, C8-10, oxybis(2-hydroxy-3,1-propanediyl) esters (CAS 92044-91-2) is characterised by a low vapour pressure (VP < 0.0001 Pa at 20°C), a high water solubility (WS: 1265 mg/L at 20°C). The log Koc range calculated for the main substance components was 0.798 – 5.440 (MCI method). Thus, the substance has the potential to adsorb to soil and suspended matter. Overall, the substance is expected to mainly distribute to water and partially sediment when released to the environment. Based on the result of the biodegradability test, the substance is ready biodegradable (102% after 28 days, according to EU method C.4 D). Thus, an extensive elimination of the substance in sewage treatment plants is expected. The concentration of the substance in conventional STP effluents is presumably marginal. Abiotic degradation via hydrolysis is considered not relevant for the substance. Moreover, the substance is not volatile and thus evaporation to the air and subsequent transport through the atmosphere to other environmental compartments is not likely.
