Description of key information

Additional information

No abiotic degradation studies are available for reaction product of p-nonylphenol, formaldehyde and diethanolamine, propoxylated. However, as the substance is known to be a stable polyether polyol, hydrolysis is not to be expected.

Based on the ready biodegradability screening test the substance is characterised as being not readily biodegradable. No simulation tests are available.

No data on the bioaccumulation potential of the substance is available. However, as the substance has a low log octanol-water partition coefficient of <3 (1.72 - 2.2), the substance may be assumed to have a low potential for bioaccumulation.

Based on its physical chemical properties (i.e. log Kow of <3), p reaction product of p-nonylphenol, formaldehyde and diethanolamine, propoxylated may be assumed to have a low potential of adsorption. For purposes of risk assessment, the organic carbon-water partitioning coefficient (Koc) is calculated from the log Kow using the equation from EUSES (non-hydrophobics QSAR). The calculated Koc value is 146 L/kg.

Data on volatilisation and distribution among compartments is not available.
