Study design
- Test substance input data:
- - Molar mass: 228.29
- Data temperature: 25°C
- Water solubility: 0.17 g/l
- Vapour pressure: 1 hPa

- Air (%):
- 1.8
- Water (%):
- 27.9
- Soil (%):
- 70.2
- Sediment (%):
- 0.14
Applicant's summary and conclusion
- Conclusions:
- Based on the modelled data it can be shown that the main part of dibutyl maleinate is distributed in the soil where about 70% of the substance can be found. About 28% reached the water body and small parts are distributed in air and sediment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
