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:
- 2009
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The test sample (Hydrolysed reaction products of furan-2,5-dione and C15-18-(linear and branched)-alkenes ref PO709-4739) was analysed in duplicate in a torsion balance by measuring the force required to pull a De Nouy ring through a Hydrolysed reaction products of furan-2,5-dione and C15-18-(linear and branched)-alkenes/water interface. Interfacial tension is a measurement relating to the hydrophilic/hydrophobic properties of a liquid.
- GLP compliance:
- no
- Type of method:
- ring method
- Key result
- Surface tension:
- 18.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 100 mg/L
- Conclusions:
- The average value obtained for the interfacial tension determination was 18.5mN/. Since the surface tension is below 60mN/m, it should be regarded as being a surface-active material.
- Executive summary:
The average value obtained for the interfacial tension determination of the test sample Hydrolysed reaction products of furan-2,5-dione and C15-18-(linear and branched)-alkenes (solvent PO709-4739) was 18.5mN/m. Since the surface tension is below 60mN/m, it should be regarded as being a surface-active material.
Reference
Duplicate results of 18.5 mN/m and 18.5 mN/m were obtained for the surface tension determination.
Description of key information
The surface tension determination of Hydrolysed reaction products of furan-2,5-dione and C15-18-(linear and branched)-alkenes (solvent PO709-4739) is reported to be 18.5 mN/m.
Key value for chemical safety assessment
- Surface tension:
- 18.5
- in mN/m at 20°C and concentration in mg/L:
- 100
Additional information
The average value obtained for the interfacial tension determination of the test sample Hydrolysed reaction products of furan-2,5-dione and C15-18-(linear and branched)-alkenes (solvent PO709-4739) was 18.5mN/m. Since the surface tension is below 60mN/m, it should be regarded as being a surface-active material.
