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:
- November 15, 2017 - November 21, 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- OECD harmonised ring method
- Specific details on test material used for the study:
- Composition: Reaction mass of dipotassium 3,3’-sulphonylbis(benzenesulphonate) and potassium 3-(phenylsulphonyl)benzenesulphonate
Purity: 92.8%
CAS# 63316-33-6 and 63316-43-8
Physical Description:White powder
Stability: Test substance was expected to be stable for the duration of testing.
Expiration Date: December 31, 2018 - Key result
- Surface tension:
- 74.8 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension was detemined to be 74.8 mN/m
- Executive summary:
In a GLP guideline study, the surface tension of the test substance was determined by the OECD harmonized ring method based on the procedures described in OECD Guidline 115 and E.U method A.5, and was found to be 74.8 mN/m. Given this result, the suface tension of aqueous solutions is not expected to play a significant role in assessing environmental fate or aquatic toxicity of this substance.

Description of key information
In a GLP guideline study, the surface tension of the test substance was determined by the OECD harmonized ring method based on the procedures described in OECD Guidline 115 and E.U method A.5, and was found to be 74.8 mN/m. Given this result, the suface tension of aqueous solutions is not expected to play a significant role in assessing environmental fate or aquatic toxicity of this substance.
Key value for chemical safety assessment
- Surface tension:
- 74.8
- in mN/m at 20°C and concentration in mg/L:
