Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The CMC value was used for water solubility measurements.
The CMC value is calculated based on injection of the test substance into water to reduce the surface tension. This lowers the surface tension of water to a plateau. The concentration of the test substance when the lower plateau is reaced is the water solubility of the test substance. - GLP compliance:
- not specified
- Type of method:
- other: CMC
- Remarks:
- Refer to principles of method above for details.
- Specific details on test material used for the study:
- Stock solution of test material (10g/l).
- Key result
- Water solubility:
- 250 mg/L
- Conc. based on:
- test mat.
- Temp.:
- 25 °C
- pH:
- > 6 - < 8
- Details on results:
- The CMC level, and thus the water solubility, is 250 mg/litre based on test substance concentration after reaching the lower plateau of the surfance tension.
- Conclusions:
- The water solubility of the test substance is 250 mg/l.
- Executive summary:
The water solubility of Dimethyldioctylammonium chloride is tested using the CMC method. Utisiling an injection approach (30 times) of stock solution 10 g/litre into clean water of surface tension 72 mN/m at room temperature. It was determined that the CMC, and thus the water solubility, for the test substance is 250 mg/l.
