Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 15 January 2018 to 23 January 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Specific details on test material used for the study:
- Source and lot/batch No.of test material: Sponsor and G316507
- Key result
- Surface tension:
- 68 mN/m
- Temp.:
- 20 °C
- Remarks on result:
- other: mean value of runs 3 and 4
- Conclusions:
- Surface tension value was determined to be 68 mN/m.
Reference
Measured value of the surface tension of water : 70.9 mN.m-1
EC standard reading for surface tension of water : 72.75 mN.m-1
The age of the solution and the corresponding surface tension for both runs (after correction for
water calibration) is detailed in Table 7:1.
Comment
Two initial test runs were conducted over 305 and 295 minutes respectively. However, the results were not stable or consistent therefore two additional tests were performed. Run 1 showed a tendency for the surface tension to decrease over time whilst the surface tension showed a slight tendency to increase but readings did not stabilise.
Description of key information
Surface tension value was determined to be 68 mN/m
Key value for chemical safety assessment
- Surface tension:
- 68
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
