- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- 27 July 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- 30 May 2008
- Deviations:
- no

- yes (incl. QA statement)
- Type of method:
- ring method
- Specific details on test material used for the study:
- - Source and lot/batch No.of test material: A065/99
- Expiration date of the lot/batch: 1st July 2019
- Purity: UVCB - Key result
- Surface tension:
- 44.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: % saturation
- Conclusions:
- The surface tension of a 90% saturated solution of the test item is 44.5 mN/m at 20°C. The test item was considered to be surface-active.
- Executive summary:
The surface tension of the test item was conducted in a GLP-compliant ring balance test following OECD guideline 115 (Envigo 2018). The study is considered to be relevant and reliable for use for this endpoint (Klimisch 1). The surface tension of a 90% saturated solution of the test item is 44.5 mN/m at 20°C. The test item was considered to be surface-active.

Description of key information
The surface tension of a 90% saturated solution of the test item is 44.5 mN/m at 20°C. The test item was considered to be surface active.
Key value for chemical safety assessment
- Surface tension:
- 44.5
Additional information
The surface tension of lithium naphthenate was determined in a GLP-compliant ring balance test following OECD guideline 115 (Envigo 2018). The study is considered to be relevant and reliable for use for this endpoint. Lithium naphthenate has a surface tension below 60 mN/m and is therefore regarded as being surface active.
