- Type of method:
- ring method
- Key result
- Surface tension:
- 57.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: corrected mean surface tension
- Conclusions:
- The surface tension of a 1 g/L dilution of test item in water was determined to be 57.5 mN/m at 20.0 °C.
- Executive summary:
The aim of the study was the determination of the surface tension of the test item in water at 20 °C ± 0.5 °C according to EC method A.5 and OECD 115 using ring method. The test was performed twice. The surface tension of a 1 g/L dilution of test item in water was determined to be 57.5 mN/m at 20.0 °C. The substance is considered to be a surface active substance.
Reference
The test was performed twice at a temperature of 20.0 °C (test 1) and 20.0 °C (test 2).

Description of key information
The surface tension of the test item in water at 20 °C ± 0.5 °C was determined according to EC method A.5 and OECD 115 using ring method. The test was performed twice. The surface tension of a 1 g/L dilution of test item in water was determined to be 57.5 mN/m at 20.0 °C. The substance is considered to be a surface active substance.
Key value for chemical safety assessment
- Surface tension:
- 57.5
- in mN/m at 20°C and concentration in mg/L:
- 1 000
