- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 24 August 2011 - 17 November 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: This study has been performed according to OECD and EC guidelines and in compliance with GLP principles.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Version / remarks:
- (1995)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Version / remarks:
- (2008)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method
- Water solubility:
- 0.076 g/L
- Temp.:
- 20 °C
- pH:
- 6.5 - 6.8
- Remarks on result:
- other: result is mean value of analysed concentrations after 24, 48 and 72 hours
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
Using the flask method the water solubility of 3,3’-DDS was determined to be 0.0764 g/l at 20°C. The pH of the aqueous samples was 6.5 – 6.8. - Executive summary:
The 3,3'-DDS is slightly soluble in water at 20°C and ph between 6.5 -6.8.
Reference
Preliminary test
The content of test substance dissolved in the water sample was 0.0794 g/l.
Main study
The maximum difference (MD) of the concentrations determined in the 24, 48 and 72 hour test samples was ≤ 15%. Based on this, the water solubility of the test substance is given as the mean value of the analysed concentrations.
A small test substance response of approximately 1% relative to the water solubility samples was observed in the blank. This is considered to have no effect on the study.
Main study - water solubility of the test substance
