Additional information

Water:

According to Regulation (EC) 1907/2006, Annex IX, Section 9.2.1.2, column 2, a simulation study on ultimate degradation in surface water does not need to be conducted if the substance is readily biodegradable. Laromer PO F33 and all of the constituents of the registration item are predicted to sufficiently degrade in the environment (see IUCLID Ch.5.2.1). Additionally, no one out of the seven main ingredients is considered to persist in the environment, neither in sediment, soil or water (IUCLID Ch. 5.2.1). Moreover, based on modeled data relevant degradation products present in concentration of ≥ 0.1% (equivalent to quantity setting in OASIS CATALOGIC: ≥0.001 [mol/mol parent]) do neither fulfill the PBT criteria (not PBT) nor the vPvB criteria (not vPvB).Therefore, no biodegradation studies in surface water will be provided.

Sediment:

According to Regulation (EC) 1907/2006, Annex IX, Section 9.2.1.2, column 2, a simulation study on ultimate degradation in sediment does not need to be conducted if the substance is readily biodegradable. Laromer PO F33 and all of the constituents of the registration item are predicted to sufficiently degrade in the environment (see IUCLID Ch.5.2.1). Additionally, no one out of the seven main ingredients is considered to persist in the environment, neither in sediment, soil or water (IUCLID Ch. 5.2.1). Moreover, based on modeled data relevant degradation products present in concentration of ≥ 0.1% (equivalent to quantity setting in OASIS CATALOGIC: ≥0.001 [mol/mol parent]) do neither fulfill the PBT criteria (not PBT) nor the vPvB criteria (not vPvB). Therefore, no biodegradation studies in sediment will be provided.
