Description of key information

 Based on available data, exposure to the sediment compartment is not likely and it can be expected that all components of Polyol TD have a low potential for adsorption to sediment. Therefore, degradation simulation testing in sediment does not need to be conducted. 

Key value for chemical safety assessment

Additional information

The study does not need to be conducted because direct and indirect exposure of soil is unlikely. Furthermore, it can be expected that all components of Polyol TD have a low potential for adsorption to sediment (log Pow < 3). The octanol-water partition coefficient for Reaction mass of 2-ethylpropane-1,3-diol (DMP) and 5-ethyl-1,3-dioxane-5-methanol (CTF) and propylidynetrimethanol (TMP) components are log Pow = 0.19 (CTF), -0.2 (DMP) and -0.8 (TMP).
