Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 27 APR 2021 - XX JUN 2022
- Reliability:
- 1 (reliable without restriction)
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- 92/69/EEC. 1992. Official Journal of the European Communities No. L383A
- 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:
- ring method
- Surface tension:
- 71.2 mN/m
- Temp.:
- 20.03 °C
- Conc.:
- 14.2 mg/L
- Conclusions:
- The mean measured corrected surface tension of the sammple was 71.2 ± 0.2 dynes/cm (mN/m)
(CV = 0.32%) 20.0 ± 0.5 ºC. - Executive summary:
A study was performed to determine the surface tension of the test substance. The study was performed based on procedures in Organisation for Economic Cooperation and Development, Guideline 115, Surface Tension of Aqueous Solutions and Council of the European Communities Directive 92/69/EEC, Official Journal of the European Communities No. L383A, Method A.5, Surface Tension under GLP.
The surface tension of the sample was determined at 20.0°C using a surface tensiometer based on the ring method. A single surface tension determination was performed on three separate aliquots of the test substance sample. The mean corrected surface tension of the substance was 71.2 ± 0.2 dynes/cm (CV = 0.32%) at 20.0 ± 0.5 ºC at a monomer-concentration of 14.2 mg/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.
