Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- other: published data
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Equilibrium surface tension was measured using the Wilhelmy Plate Technique.
- GLP compliance:
- not specified
- Type of method:
- plate method
- Surface tension:
- 66.53 mN/m
- Temp.:
- 25 °C
- Conc.:
- 0.101 other: mg/m2
- Remarks on result:
- other: 66.53 dyne/centimeter (dyne/cm ) = 66.53 millinewnon/meter (mN/m). Water solubility of Oleyl Alcohol: 0.042mg/L. In the study oleyl alcohol is assumed to be "insoluble". Concentrations are reported as surface concentrations only.
- Conclusions:
- A surface tension value of 66.5 mN/m at a concentration at the surface of 0.101 mg/m2 was determined at 25ºC in a reliable study conducted according to generally accepted scientific principles.
