Additional information

Based on the result of the octanol/water partition coefficient (log Kow of -0.379) tripropylene glycol is expected to have a low potential for adsorption/desorption.

 

The calculated Henry's law constant at environmental relevant temperature is 0.129 Pa.m3/mol using EUSES calculation (The European Union System for the Evaluation of Substances, 2008)

Volatility is not expected to be a significant fate process due to its low vapor pressure and high water solubility.

Using fugacity modelling (Mackay level III) tripropylene glycol will preferentially partition into water (9%), soil (34%) and sediment (57%) if released into the environment (OECD SIDS, 1994).
