Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2007-03-28 to 2008-04-30
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- 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.
- GLP compliance:
- no
- Type of method:
- other: comparable to flask method
- Key result
- Water solubility:
- ca. 23.2 g/L
- Temp.:
- 25 °C
- Remarks on result:
- other: The pH value was not determined.
- Water solubility:
- ca. 25.5 g/L
- Temp.:
- 40 °C
- Remarks on result:
- other: The pH value was not determined.
- Water solubility:
- ca. 34.1 g/L
- Temp.:
- 60 °C
- Remarks on result:
- other: The pH value was not determined.
- Conclusions:
- The water solubility of TDI-Urone was determined. It is considered to be very soluble (> 10000 mg/L).
- Executive summary:
The water solubility of TDI-Urone was determined with a method equivalent to the OECD guideline 105. The substance was stirred in water at temperatures of 25°C, 40°C and 65°C to to get a saturated solution. The supernatant was filtered and the eluat was dried at
45-55°C in a vacuum drying oven. The concentration of the substance was determined by reweighing.
The water solubility of TDI-Urone at 25°C was determined to be 2.32 g/100 g or 23.2 g/l water. Therefore, TDI-Urone is very soluble in water.
