Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2020
- 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

- Key result
- Surface tension:
- 57.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1.013 g/L
- Conclusions:
- A mean value of 57.7 mN/m was determined for a solution of diisobutyl phosphate containing approx. 1g/L at 20 °C.
- Executive summary:
The surface tension properties of diisobutyl phosphate at 20 °C were investigated according to DIN EN 14370 corresponding to A.5, Council Regulations EC No 440/2008 and OECD 115 using a plate tensiometer. The surface tension was determined in a solution of approx. 1 g/L at 20 °C. For verification demineralized water was used as reference with a value of 72.75 mN/m.
A mean value of 57.7 mN/m was determined for the test solution.
