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:
- 17/04/2012 - 01/08/2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- 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
- Principles of method if other than guideline:
- Not relevant
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Surface tension:
- 57.2 - 60.3 mN/m
- Temp.:
- 22.2 °C
- Remarks on result:
- other: pH during test was 5.2. Based on the results, the test item is considered to be surface-active.
- Conclusions:
- The surface tension of Diacid 1550 is 57.2 to 60.3 mN/m.
- Executive summary:
The surface tension of Diacid 1550 was investigated according to OECD guideline 115 under GLP using the rind method. The surface tension of a 90% saturated solution of Diacid 1550 was found to be 57.2 - 60.3 mN/m at 22.2ºC and pH 5.2. Based on this result, Diacid 1550 is considered to be surface-active.
