Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 2018
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- plate method
- Specific details on test material used for the study:
- aqueous solution
- Key result
- Surface tension:
- >= 50.57 - <= 60.23 mN/m
- Temp.:
- 22.2 °C
- Conc.:
- 1 g/L
- Conclusions:
- hydroxyethyl-DETA derivatives is surface active
- Executive summary:
Over a period of three hours, changes in the surface tension were detected. In dependence on time and temperature, values between 50.57 and 60.23 mN/m were recorded.
After the fourth measurement, no significant changes were observed. As the determined surface tension ofhydroxyethyl-DETA derivativesat the plateau was lower than 60 mN/m, the test item must be classified assurface active.
