Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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:
- 4 September - 8 December 1999
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: done under GLP and OECD method
- Qualifier:
- according to guideline
- Guideline:
- other: Directive 92/69/EEC, Method A5, Surface tension determined with a surface tension/torsion balance using the OECD harmonised ring method
- GLP compliance:
- yes
- Surface tension:
- 52.53 mN/m
- Temp.:
- 19.5 °C
- Conc.:
- 90 vol%
- Conclusions:
- The surface tension of a 90% saturated aqueous solution is 52.53 mN/m at 19.5°C. The test substance is considered to be surface-active since the surface tension is less than 60 mN/m.

Description of key information
The surface tension of a 90% saturated aqueous solution is 52.53 mN/m at 19.5°C. The test substance is considered to be surface-active since the surface tension is less than 60 mN/m.
Key value for chemical safety assessment
- Surface tension:
- 52.53
- in mN/m at 20°C and concentration in mg/L:
- 463.5
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.
