Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- 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:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 63.4 - <= 71.6 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of the test item was determined to be 63.4 - 71.6 mN/m.
- Executive summary:
The surface tension of dilithium tetraborate was determined to be 63.4 - 71.6 mN/m using the ring method in accordance with EU Method A5.
Reference
Solutions of 1 g/L and 1 mg/L were prepared and observed to become cloudy. Both solutions were then left over 60 hours and after this period, the solution was found to be clear. Another 1g/L was then prepared and sonicated. After approximately 3 hours the sample had gone into solution. Measurements were then taken.
A second solution was prepared in the same way and sonicated until the solution was clear (approximately 3 hours 5 minutes).
Due to the extended solubilisation time and the difference in readings between the two test then a range has been reported for the surface tension rather than a mean.
Result : 63.4 - 71.6 mN.m-1 (range)
