- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012-02-09 to 2012-02-10
- 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
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed 2010-10-20
- Type of method:
- ring method
- Surface tension:
- 38.89 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: % saturated solution
- Remarks on result:
- other: standard deviation of < 0.02 mN/m
- Conclusions:
- The surface tension of a 90 % saturated solution of Octanoic acid, zinc salt, basic was determined to be 38.89 mN/m with a standard deviation of 0.02 mN/m at a mean temperature of 20.0 °C. Since the surface tension is lower than 60 mN/m, Octanoic acid, zinc salt, basic can be regarded as surface-active substance according to Council Regulation (EC) No. 440/2008 Method A.5.

Description of key information
The surface tension of a 90 % saturated solution of octanoic acid, zinc salt, basic was determined to be 38.89 mN/m with a standard deviation of 0.02 mN/m at a mean temperature of 20.0 °C. Octanoic acid, zinc salt, basic can be regarded as surface-active substance.
Key value for chemical safety assessment
- Surface tension:
- 38.89
Additional information
Octanoic acid, zinc salt, basic can be regarded as surface-active substance according to Council Regulation (EC) No. 440/2008 Method A.5
as the surface tension is lower than 60 mN/m.
