Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- yes
- Remarks:
- : Backweiging to determine concentration of the substance; pH was not determined;
- Principles of method if other than guideline:
- The saturated solution of the test substance in water was prepared at temperatures of 25, 40 and 60°C. The saturated solution was filtered and the flow through was dried in a vacuum oven. The test substance was weighed and the concentration was determined.

Applicant's summary and conclusion
- Conclusions:
- The water solubility of MDI-Urone was determined. It is considered to be moderately soluble.
- Executive summary:
The water solubility of MDI-Urone was determined with a method equivalent to the OECD guideline 105. The substance was stirred in water at temperatures of 25°C to get a saturated solution. The concentration of the substance was determined by HPLC.
The water solubility of MDI-Urone at 25°C was determined to be 45 mg/l water.
