Description of key information

Additional information

Despite its moderate/ high vapor pressure (21.3 Pa at 20 °C), diethylenetriamine is expected to be essentially non-volatile from water due to its miscibility in water and occurrence as a cationic (multi-protonated) species under pH conditions occurring in the environment. The Substance exhibits a high affinity for adsorption to soil and sediment, despite these hydrophilic properties, due to participation in cation exchange interactions with soil minerals (i.e., clay). Collectively, these properties of diethylenetriamine will result in low potential for inter-media transport in the environment. Atmospheric emissions will be readily deposited to soil and surface waters by both wet-a nd dry deposition processes. Conversely, emissions to soil or water will neither result in volatilization to air, nor significant exchange between soil and water, due to high water solubility and high affinity for soil/sediment.
