Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The flask method was chosen for the determination of the water solubility of DCM. The water solubility of the test substance at 19.8°C ± 0.5 °C was
> 1000 g/1. The pH of the aqueous samples after 72 hours stirring was 1.73.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
