- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Version / remarks:
- preliminary test
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Version / remarks:
- preliminary test
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- other: preliminary test and turbidity method
- Water solubility:
- > 0.5 - < 1.25 mg/L
- Conc. based on:
- act. ingr.
- Temp.:
- 23 °C
- pH:
- 5
- Conclusions:
- The water solubility of C12-18 alkyldimethyl ammonium chloride was determined to be <1.25 mg/L (turbidity method).
- Executive summary:
The water solubility of C12-18 alkyldimethyl ammonium chloride was determined by turbidity measurements and visual examination according the OECD Test Guideline 105 and EU method A.6.
In a preliminary test separation of the test item from the aqueous phase by centrifugation or filtration was not possible. Therefore, the main test, where separation of the test substance from the aqueous phase is necessary, was not performed. Alternatively, solutions with defined nominal concentrations were prepared and tested for turbidity.
The water solubility of C12-18 alkyldimethyl ammonium chloride was determined to be <1.25 mg/L at 23°C.
Reference
The nominal concentrations 0.01 – 0.5 mg/L could not be differentiated from the blank.
