Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2007
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:

- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- year of the guideline: 1996
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: ISO 304
- Deviations:

- Type of method:
- other: interfacial tension balance
- Key result
- Surface tension:
- 70.9 mN/m
- Temp.:
- 21 °C
- Conc.:
- 1.05 g/L
- Remarks on result:
- other: pH = 9.5
- Conclusions:
- The surface tension of a 1.05 g/L solution of Incozol 3 and/or degradation products has been determined to be 70.9 mN/m at 21.0 ± 0.5 °C. Incozol 3 and / or degredation products are considered not to be a surface-active material.
- Executive summary:
The surface tension was determined according to Commission Directive 92/69/EEC method A.5 using a white electrical Institute interfacial tension balance. Incozol 3 is known to be highly reactive towards water. Therefore, the value obtained for the surface tension is most likely that of the hydrolysis products and not of the parent material. The surface tension of a 1.05 g/L solution of Incozol 3 and/or degradation products has been determined to be 70.9 mN/m at 21.0 ± 0.5 °C. Incozol 3 and/or degradation products are considered not to be a surface-active material.
Reference
The test material is known to be highly reactiv towards water.
