Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 03 June 2015 to 05 February 2016
- 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:
- 32 mN/m
- Temp.:
- 22 °C
- Remarks on result:
- other: Mean value from duplicate determinations that were nominally 90 % of saturated solution
- Conclusions:
- The surface tension of the test item was assessed in accordance with OECD Guideline 115. The surface tension of test item prepared at 90 % saturation in water was determined to be 32.0 mN/m at 22.0 ± 0.5°C. The test item was 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 (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 test item prepared at 90 % saturation in water was determined to be 32.0 mN/m at 22.0 ± 0.5°C.
CONCLUSION
The test item was considered to be surface active.

Description of key information
The surface tension of the test item was assessed in accordance with OECD Guideline 115. The surface tension of test item prepared at 90 % saturation in water was determined to be 32.0 mN/m at 22.0 ± 0.5°C. The test item was considered to be surface active.
Key value for chemical safety assessment
- Surface tension:
- 32
- in mN/m at 20°C and concentration in mg/L:
- 1 000
