Additional information

Reaction mass of 2-hydroxyethyl laurate and ethylene dilaurate is a multi-constituent substance with a mono-and a diester component. Both components are assumed to have a low vapor pressure (0.018 and 0.153 Pa at 25 °C, QSAR). Based on the Log Koc values the adsorption potential is assumed to be moderate for monoester and high for diester (log Koc: 2.316 - 6.35, at 25°C, QSAR). If released into the environment the mono-ester component is expected due to its moderate log Kow and log Koc values to partition between the water phase and the organic matter in soils and sediments. The di-ester component on the other hand is expected to partition mainly to organic matter associated with sediment and soil particles as well as activated sludge in sewage treatment plants due to its high potential for adsorption. Nevertheless since the substance is readily biodegradable a short retention time is expected. Evaporation and the subsequent transport via the atmospheric compartment is not expected due to the low vapour pressure.
