Description of key information

The readily biodegradation of Accelerator (PT 25E or PT 25E/2) under the conditions of the carbon dioxide (CO2) evolution test (modified Sturm test) was investigated according to OECD guideline 301 B and GLP principles. A single test concentration of 12 mg/L (as TOC) was tested during 28 days. Based on the obtained results, Accelerator (PT 25E or PT 25E/2) was not readily biodegradable. The study is considered to be reliable without restrictions.

In accordance with column 2 of REACH Annex IX the studies Simulation testing on ultimate degradation in surface water (section 9.2.1.2), Sediment simulation testing (section 9.2.1.4) and Simulation testing on ultimate degradation in soil (section 9.2.1.3) do not need to be conducted as the Chemical Safety Assessment does not indicate the need to investigate further the degradation of the substance.
