Description of key information

In the chemical safety assessment performed according to Article 14(3) in connection with Annex I section 3 (Environmental Hazard Assessment) of the REACH regulation no hazard was identified. Therefore according to REACH Annex I (5.0) exposure assessment is not necessary. In addition, Bis-MPA has a low potential for adsorption to sediment (log Kow is -1.1) and is readily biodegradable. For a substance considered "readily biodegradable", it can be assumed that it will be completely biodegraded within the STP process and as a consequence any transfer to the sediment compartment is not expected. Moreover, acute aquatic toxicity tests show no hazard of Bis-MPA.
