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:
- 25 July 2017 - 14 Sept 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
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: 16VL8189
- Expiration date of the lot/batch: 04 Feb 2018
- Purity test date: 05 Aug 2016
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: ambient (=< 30 deg C), dark, dry
TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing: No - Key result
- Surface tension:
- 71.7 mN/m
- Temp.:
- 19.8 °C
- Conc.:
- 100 other: mg/100 mL
- Conclusions:
- The mean of the two determinations of the surface tension was determined to be 71.7 mN/m at 19.8 deg C.
Since the test item showed a surface tension higher than 60 mN/m under the conditions of the method, GUP will not be considered as surface active according to Regulation (EC) No. 440/2008 - Executive summary:
The surface tension of GUP was determined in accordance with OECD Guideline 115 and EC Method A5; ring method.
The mean of the two determinations of the surface tension was determined to be 71.7 mN/m at 19.8 °C.
Since the test item showed a surface tension higher than 60 mN/m under the conditions of the method, GUP will not be considered as surface active according to Regulation (EC) No. 440/2008

Description of key information
The mean of the two determinations of the surface tension was determined to be 71.7 mN/m at 19.8 °C.
Since the test item showed a surface tension higher than 60 mN/m under the conditions of the method, GUP will not be considered as surface active according to Regulation (EC) No. 440/2008
Key value for chemical safety assessment
- Surface tension:
- 71.7
- in mN/m at 20°C and concentration in mg/L:
- 100.1
