Description of key information

Key value for chemical safety assessment

Additional information

According to Regulation (EC) 1907 (2006), Annex IX, Section, Column 2, a study on soil simulation testing does not need to be conducted as the direct and indirect exposure of the soil compartment is unlikely and as the chemical safety assessment according to Annex I indicates that there is no need to investigate further the degradation of the substance and its degradation products.  For the substance (MIPDA, CAS 93940-97-7) only industrial uses with adequate risk mitigating measures are foreseen. Indirect exposure via sewage sludge is not expected as sewage sludge from sewage treatment plants treating industrial sewage are expected to be incinerated. The substance is not supposed to be directly applied to soil. In addition, environmental exposure through widespread uses by professionals and consumers is excluded.  Further, the substance does not have the potential to bioaccumulate nor is it considered as a PBT/vPvB substance. In addition, the risk assessment results in Risk Characterization Ratios below 1. Hence, soil is not expected to be a compartment of concern. No soil simulation testing will be performed.
