Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 2012-02-22 - 2012-02-23
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- ring method
- Key result
- Surface tension:
- 57.8 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: The surface tension result is corrected for water calibration and ring dimensions (Harkins-Jordan). The solution age was 5 minutes for test No 1 and 10 minutes for test No 2.
- Conclusions:
- The surface tension of the substance was determined to be 57.8 mN/m at a test concentration of 1 g/L and at 20 °C. The substance is concluded to be capable of reducing the surface tension of water and is thus considered as a surfac active substance (surface tension <60 mN/m).
Reference
Calibration:
The measured value of the surface tension of water: 68.0 mN/m
EC standard reading for surface tension of water: 72.75 mN/m
Calibration factor is: 72.75/68.0 = 1.07
The calibration factor is determined by measuring the surface tension of water and comparing the value obtained in literature. The corrected value is taken from a table compiled on the basis of the Harkins-Jordan correction.
The duplicate runs provided identical results.
Description of key information
The surface tension of the substance was determined in a GLP study according to test method EC A.5, to be 57.8 mN/m at a test concentration of 1 g/L and at 20 °C, following the ring method (Younis S, 2012).
Key value for chemical safety assessment
- Surface tension:
- 57.8
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The substance is concluded to be capable of reducing the surface tension of water and is thus considered to be surface active.
