Administrative data

biodegradation in water: sediment simulation testing
Type of information:
experimental study planned
Study period:
Testing proposal according to REACH Annex IX
Justification for type of information:
Simulation testing indicates that the substance undergoes rapid primary degradation. The registrants are evaluating degradation product formation and have planned sediment degradation tests to take account of these findings for other regulatory regions. These studies will be performed in the near future. The study will be conducted according to OECD TG 308, EC (eventually with specific modifications as proposed in recent scientific publications).

Details on test material:
- Physical state: Pale yellow powder
- Analytical purity: 99.04%
- Lot/batch No.: 5/87; Indent 9200/9622
- Storage condition of test material: Following its arrival in Compound Control this test substance was stored in the dark at ambient temperature.
- Stability: Infra-red spectra of the test substance were taken. There were no significant differences between the spectra and so, on this basis, the test substance was judged to have been stable for the duration of this study.
