- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- 2008
- Deviations:

- GLP compliance:
- yes
- Type of method:
- ring method
- Key result
- Surface tension:
- 29.83 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The present study was performed in order to determine the surface tension of Rhamnolipid according to OECD Test Guideline 115 (1995) and Council Regulation (EC) No. 440/2008, Method A.5. An aqueous solution (1 g/L) of the test item revealed a surface tension of 29.83 mN/m, therefore the substance is considered to be surface active in comparison to water.
- Executive summary:
According to OECD Test Guideline 115 the surface tension of Rhamnolipid was determined using the ring method. The mean surface tension was determined to be 29.83 mN/m at 20°C (1 g/L).
