- Key result
- Surface tension:
- 63.1 mN/m
- Temp.:
- 20.1 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: corrected mean surface tension as dilution in water with 1 g/L
- Conclusions:
- The surface tension of a 1 g/L dilution of the test substance in water was determined to be 63.1 mN/m at 20.1°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 the test substance in water was determined to be 63.1 mN/m at 20.1°C. The susbtance is not considered to be surface active.
Reference
The test was performed twice at a temperature of 20.1 °C (test 1, 99.8 mg test material in 100 mL) and 20.1 °C (test 2, 100.8 mg test material in 100 mL).

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 the test substance in water was determined to be 63.1 mN/m at 20.1°C. It is concluded that the substance is not a surface active substance.
Key value for chemical safety assessment
- Surface tension:
- 63.1
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
