Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2016-04-20 to 2016-04-21
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 57.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: A solution with about 90 % of the saturation solubility of Caprinoguanamine was made in ultra-pure water.
- Conclusions:
- The mean surface tension was determined to be 57.7 mN/m.
The test item can be regarded as surface active as the determined surface tension is < 60 mN/m (EC method A5, chapter 3.2) according to the used procedure. - Executive summary:
The surface tension of Caprinoguanamine was determined according to EC method A5 and OECD 115. A solution with about 90 % of the saturation solubility of Caprinoguanamine was made in ultra-pure water. The test was performed four times at a temperature of 20 °C controlled within ± 0.5 °C. The mean surface tension was determined to be 57.7 mN/m.
The test item can be regarded as surface active as the determined surface tension is < 60 mN/m (EC method A5, chapter 3.2) according to the used procedure.
