- Adequacy of study:
- key study
- Study period:
- 15/10/2007-08/01/2008
- 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
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Surface tension:
- 50.9 mN/m
- Temp.:
- 22 °C
- Conc.:
- 0.01 g/L
- Remarks on result:
- other: The test material is considered to be a surface-active material
- Conclusions:
- The surface tension of solution of test material saturated at a nominal concentration of 1.00x10^-2 g/L has been determined to be 50.9 mN/m at 22.0±0.5ºC. The test material is considered to be a surface-active material.
- Executive summary:
The surface Tension is 50.9 mN/m (using a sample solution saturated at a nominal concentration of 1.00 x 10^-2 g/L) at 22.0±0.5ºC, using a ring method based on ISO 304, Method 115 of the OECD Guidelines.
