- guideline 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

- Type of method:
- ring method
- Specific details on test material used for the study:
- - Test material: Balsalazide acid
- Batch number: 0400
- Expiry date: April 2019
- Storage: Room temperature - Key result
- Surface tension:
- 67.1 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: % of its saturation
- Conclusions:
- The surface tension of Balsalazide acid in an aqueous solution at 90% of its saturation was found to be 67.1 mN/m at 20°C. Therefore, Balsalazide acid is not regarded as a surface-active material.

Description of key information
The surface tension of the test item, Balsalazide acid was determined according to OECD Guideline 115 and EC Method A.5 at 20°C and was found to be 67.1 mN/m in an aqueous solution at 90% of its saturation. Therefore, Balsalazide acid is not regarded as a surface active material.
Key value for chemical safety assessment
- Surface tension:
- 67.1
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
