Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 2014-06-17 to 2014-09-05
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- (2008)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- (1995)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- OECD harmonised ring method
- Surface tension:
- 71.3 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of an 1 g/L aqueous solution of the substance has been determined as 71.3 mN/m at 20°C. The substance is not surface active.
- Executive summary:
In a GLP-compliant study in accordance with EC A.5 and OECD 115 using the OECD Harmonized ring method, the surface tension of an 1 g/L aqueous solution of the substance has been determined as 71.3 mN/m at 20°C. Because this is not < 60 mN/m, the substance is not surface active according to the EC A.5 guideline.

Description of key information
In a GLP-compliant study in accordance with EC A.5 and OECD 115 using the OECD Harmonized ring method, the surface tension of an 1 g/L aqueous solution of the substance has been determined as 71.3 mN/m at 20°C. Because this is not < 60 mN/m, the substance is not surface active according to the EC A.5 guideline.
Key value for chemical safety assessment
- Surface tension:
- 71.3
- 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
