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:
- 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Principles of method if other than guideline:
- The surface tension and surface tension in liquid solutions was determined. The static surface tension of a liquid is determined according to the ring method using a K10ST difital tensiometer of Krüss. The maximum force required to detach the ring from the liquid surface is measured by a sensitive torsion balance. The surface tension of aqueous systems containing sparsely soluble compounds is readily measured by OECD Guideline 115. In this case, aqueous solutions of a resin are prepared at 90% of its solubility limit when known. Otherwise, a saturated solution is prepared in deionized water.
- GLP compliance:
- no
- Type of method:
- ring method
- Key result
- Surface tension:
- ca. 38.6 mN/m
- Temp.:
- 20 °C
- Remarks on result:
- other: Test substance liquid
- Key result
- Surface tension:
- ca. 52.7 mN/m
- Temp.:
- 20 °C
- Remarks on result:
- other: Saturated solution (30 mg/L deionized water)
- Conclusions:
- Under the test conditions, the surface tension of di-TMPTTA (liquid) was found to be 38.6 mN/m at 20°C and the surface tension of a saturated solution was found to be 52.7 mN/m.
- Executive summary:
The study was performed to determine the surface tension of the di-TMPTTA using the ring method following OECD Guideline 115. Under the test conditions, the surface tension of the liquid test substance was found to be 38.6 mN/m and the surface tension of a saturated solution was found to be 52.7 mN/m at 20°C (Jeuniaux, 2012).
