Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- from 20 December 2018 to 28 December 2018
- 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:
- 2016
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- 1995
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- OECD harmonised ring method
- Specific details on test material used for the study:
- water solubility: 0.715 g/L (20°C)
- Key result
- Surface tension:
- 50.3 mN/m
- Temp.:
- 20 °C
- Remarks on result:
- other: Conc.= 90% saturation in water
- Conclusions:
- The surface tension of an aqueous substance solution at 90% saturation was determined to be 50.3 mN/m (at 20°C).
- Executive summary:
The OECD harmonized ring method was used in a GLP study based on EC A.5 and OECD 115. The surface tension of an aqueous substance solution at 90% saturation was determined to be 50.3 mN/m (at 20°C). According to EC A.5 the substance is surface active. The concentration tested was at approximate 0.6 g/L.

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.
