Description of key information

Additional information

The substance Fatty acids, C18-unsatd., dimers, reaction products with fatty acids, C14-18 and C16-18-unsatd. and propylidynemethanol (CAS 162353-70-0) is not expected to be present in the atmosphere or to accumulate in natural waters. This assumption is based on the low vapour pressure and the low water solubility (WS: (< 25 µg/L at 20 °C, pH = 6.3, VP < 0.0001 Pa at 20 °C). Abiotic degradation by hydrolysis is negible according to experimental data available for an analogue substance and the estimated half-lifes of the main substance components. Under environmental conditions the substance is expected to be mainly eliminated by biodegradation.
