Additional information

No abiotic degradation studies are available for Polyol IXOL B350. However, the substance is known to be a stable polyether polyol, hydrolysis is therefore not expected.

Polyol IXOL B350 is not readily biodegradable under aerobic conditions. No simulation tests are available. The degradation rate constants used in the assessment are:

No data on the bioaccumulation of Polyol IXOL B350 is available. However, as the substance has a log octanol-water partition coefficient less than 3 (the log Kow ranges from -0.3 to 3.3, with an average log Kow of 1.29), the substance has a low potential for bioaccumulation.

Based on its physical chemical properties Polyol IXOL B350 is expected to have a low potential of adsorption (the log Kow ranges from -0.3 to 3.3, with an average log Kow of 1.29).

Using a fugacity model (Mackay Level I), the theoretical distribution of Polyol IXOL B350 based on physico-chemical properties between environmental compartments at equilibrium can be calculated. The results indicate that 98.3% is distributed to the aquatic compartment, negligible volatilisation may be expected from water and adsorption to particulate matter is poor.
