- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 29 - 30 Jan 2003
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- 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
- Type of method:
- OECD harmonised ring method
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Batch No.of test material: K100
- Expiration date of the lot/batch: August 12, 2004
- Purity: 98.7%
- Purity test date: February 2, 2005 - Key result
- Surface tension:
- 70.45 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of PFBSK+ at 1.0 g/L and 20.0 °C is 70.45 mN/m as determined by EU Method A.5.
- Executive summary:
The surface tension of PFBSK+ was tested using the OECD harmonized ring method. The surface tension was determined as the mean of ten measurements done under comparable conditions. The study was conducted in accordance with EU Method A.5 and was GLP compliant, however detailed documentation was not available; therefore the study is considered reliable with restrictions.
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 24 Apr 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- OECD harmonised ring method
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material:41-2600-9264-2 lot 30073 - Key result
- Surface tension:
- 70.1 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of PFBSK+ at 1.0 g/L and 20.0 °C is 70.1 mN/m as determined by OECD Method 115.
- Executive summary:
The surface tension of PFBSK+ was tested using the OECD harmonized ring method. The surface tension was determined as the mean of two measurements done under comparable conditions. The study was conducted in accordance with OECD 115 but was not GLP compliant; therefore the study is considered reliable with restrictions.

Additional information
The surface tension of PFBSK+ was tested using the OECD harmonized ring method. The surface tension was determined as the mean of ten measurements done under comparable conditions. The study was conducted in accordance with EU Method A.5 and was GLP compliant, however detailed documentation was not available; therefore the study is considered reliable with restrictions. In a supporting study, the surface tension of PFBSK+ at 1.0 g/L and 20.0 °C was 70.1 mN/m. The study was conducted in accordance with OECD 115 but was not GLP compliant; therefore the study is considered reliable with restrictions.
