Description of key information

The members of the hydrotrope category are readily biodegradable and have a very low logPow. It can be assumed that they will be completely biologically degraded within the STP process.  Therefore tests on sediment organisms are not provided. Since the physicochemical data indicate that the substances are unlikely to be  bioaccumulative (low log Kow), a significant distribution into the sediment compartment and a significant exposure of sediment organisms is not expected. Hence, information about effects on sediment organisms is not required. For the purposes of the risk assessment, PNEC aqua are converted to PNEC sediment using the equilibrium partitioning method.
