- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14 September 2017 – 04 January 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: Titration against hydrochloric acid
- Key result
- Water solubility:
- 141.2 g/L
- Temp.:
- 20 °C
- pH:
- >= 9.35 - <= 9.44
- Details on results:
- Preliminary result: Some of the test material still remained after occasional shaking for 60 minutes. The shake flask method estimated that the water solubility was <1g/L.
Formal analysis: The first analysis determined the water solubility to be 132 g/L. The change in solubility of the test material between day 2 and day 3 was within the expected reproducibility values. However there was a general trend in that the solubility increased with time. In accordance with the ECHA guidelines the testing was repeated with an increased equilibration time. The equilibration period was increased from 24 to 168 hours. The water solubility was determined to be 141.2 g/L with the extended equiliabration time. Full results are presented below. - Conclusions:
- The water solubility of the test item was determined to be 141.2 g/L
- Executive summary:
The water solubility of dilithium tetraborate was determined to be 141.2 g/L using the titration method in accordance with EU method A6.
