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:
- From November 09, 2017 to March 06, 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- non-GLP; surface tension measurements were done directly at 1 g/L
- Reason / purpose for cross-reference:
- reference to same 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:
- no
- Remarks:
- The study was conducted in a facility which operates in accordance with Good Laboratory Practice principles; however no claim of GLP compliance was intended nor is made for this study
- Type of method:
- ring method
- Key result
- Surface tension:
- ca. 48 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- Under the study conditions, the the surface tension of 1 g/L nominal test concentration in water was determined to be 48 ± 0.5 mN/m at 20 ± 0.5ºC; therefore, was considered to be surface-active.
- Executive summary:
A study was conducted to determine the surface tension of the test substance, using the ring method, according to the OECD Guideline 115 and EU Method A.5. Under the conditions of the study, the surface tension of 1 g/L nominal test concentration in water was determined to be 48 ± 0.5 mN/m at 20 ± 0.5ºC. Therefore, the test substance was considered to be surface-active (Envigo, 2018).
Reference
Due to the complex nature and composition of the test substance, it was considered not completely applicable to follow the EC A.5 and OECD 115 guidelines with regard to sample preparation. Therefore, the surface tension of a nominally 1 g/L dispersion of test substance in water was used as a worst case scenario based on the maximum sample concentration specified in the guidelines. According to criteria stated in EC Method A.5, substances showing a surface tension lower than 60 mN/m under the conditions of this method should be regarded as being surface active.
Description of key information
The surface tension of the test substance was determined using the ring method, according to OECD Guideline 115 and EU method A.5 (Envigo, 2018).
Key value for chemical safety assessment
- Surface tension:
- 48
- in mN/m at 20°C and concentration in mg/L:
- 1 000
