Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 18 January 2017 to 10 February 2017
- 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
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 70.5 mN/m
- Temp.:
- 21.5 °C
- Conc.:
- 1 000 mg/L
- Remarks on result:
- other: sample solutions prepared at nominal concentration of 1.1 g/L and diluted to 90 % saturation
- Conclusions:
- The surface tension of solutions prepared at nominally 90 % saturation of test item in water was determined to be 70.5±0.5 mN/m at 21.5 ± 0.5 °C. The substance was not considered to be surface-active.
- Executive summary:
GUIDELINE
The determination was carried out by a ring method, using a procedure designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for the Testing of Chemicals, 27 July 1995.
RESULTS
The surface tension of solutions prepared at nominally 90 % saturation of test item in water was determined to be 70.5 ± 0.5 mN/m at 21.5 ± 0.5 °C. The substance was not considered to be surface-active.

Description of key information
The surface tension of solutions prepared at nominally 90 % saturation of test item in water was determined to be 70.5 ± 0.5 mN/m at 21.5 ± 0.5 °C. The substance was not considered to be surface-active (OECD 115 and EU Method A.5).
Key value for chemical safety assessment
- Surface tension:
- 70.5
- in mN/m at 20°C and concentration in mg/L:
- 1 000
