Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- Surface Tension Measurements should be performed on a solution at either 90 % of the solubility limit or 1 g/l (where viscosity permits), whichever is smaller. The test item, Sophorolipids (water solution), contained 58.4% dry matter, which is equivalent to a concentration of 584 g/L. Although this test solution was too concentration, the results are similar to the key study. Thus the study is considered reliable with acceptable restrictions and has been retained as a supporting study.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- not specified
- GLP compliance:
- no
- Type of method:
- plate method
- Surface tension:
- >= 38.24 - <= 38.66 mN/m
- Temp.:
- 20.1 °C
- Conc.:
- 100 vol%
- Remarks on result:
- other: the tested item is the substance as produced (60% of dry substance in water)
- Conclusions:
- The surface tension of Sophorolipids is 38.45 mN/m +/- 0.21 mN/m.
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2019
- 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)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 30.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of a solution of Freeze dried Sopholiance in ultrapure water
(nominal 1.0 g/l) was determined according to the OECD Guideline No. 115, using the
ring method.
The result is:
30.5 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
Two studies for assessing the surface tension of a solution of the registered substance are available. Both were perfomred according to OECD Guideline 115. The results obtained were 38.45 mN/m (Processium 2012, plate method, reliability 2, non-GLP, supporting study) and 30.5 mN/m (Dutriez 2019, ring method, reliability 1, GLP, key study). The latter has been selected as the key value. According to both tests, the registered substance is considered is surface active (surface tension < 60 mN/m).
Key value for chemical safety assessment
- Surface tension:
- 30.5
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Surface Tension Measurements should be performed on a solution at either 90 % of the solubility limit or 1 g/l (where viscosity permits), whichever is smaller. The test item in the Processium 2012 study report is described as Sophorolipids (water solution, contained 58.4% dry matter), which is equivalent to a concentration of 584 g/L. This concentration is too high but because the results are similar to the key study, which was performed at the required concentration of 1g/L, it has retained as a supporting study.
