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:
- January - February 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- 1995
- Deviations:
- no
- GLP compliance:

- Type of method:
- ring method
- Specific details on test material used for the study:
- GR-50-1408 is the Givaudan identification code which was employed for ROSYFOLIA during the early, developmental and testing period.
- Key result
- Surface tension:
- 38.6 mN/m
- Temp.:
- 20 °C
- Conc.:
- 60.82 mg/L
- Conclusions:
- The surface tension of a solution of GR-50-1408 in ultrapure water (60.82 mg/L, approximately 87% of the saturation concentration) was determined according to the OECD Guideline No. 115, using the ring method. The result is, 38.6 mN/m.
Therefore, according to this test, it was considered that the test material and/or the degradation product are surface active (surface tension < 60 mN/m).
Reference
Determination | Surface tension reading (mN/m) |
1 | 38.5 |
2 | 38.7 |
3 | 38.6 |
4 | 38.5 |
5 | 38.7 |
6 | 38.7 |
Mean reading | 38.6 |
The surface tension was measured using test substance solution at a concentration of ~87% of the saturation concentration, slightly lower than the concentration of 90% of the saturation concentration stipulated in the OECD guideline No. 115. However, the fact that surface activity was observed even at this slightly lower concentration allows us to interpret the results observed:
The results in the above table show that there is no significant change of the measured surface tension. This it can be concluded that equilibrium is reached. Thus the results obtained were averaged, to give the surface tension of the solution.
The result is: 38.6 mN/m
Therefore, according to this test, it was considered that the test material is surface active (surface tension < 60 mN/m).
Description of key information
The surface tension of a solution of GR-50-1408 in ultrapure water (56.5 mg/L, -81% of the saturation concentration) was determined according to the OECD Guideline No. 115, using the ring method. The result is, 38.6 mN/m.
Therefore, accoridng to this test, it was considered that the test material and/or the degradation product are surface active (surface tension < 60 mN/m)
Key value for chemical safety assessment
- Surface tension:
- 38.6
- in mN/m at 20°C and concentration in mg/L:
- 60.82
