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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 1991
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: 84/449/EWG, A.5; (Ringmethode)
- GLP compliance:
- yes
- Type of method:
- other: not specified in the test report
- Surface tension:
- 71.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 0.05 mg/L
- Remarks on result:
- other: saturated aqeous solution
- Surface tension:
- 35.1 mN/m
- Temp.:
- 20 °C
- Conc.:
- 100 vol%
- Remarks on result:
- other: pure substance
- Conclusions:
- The surface tension of the saturated aqueous solution of the test item is 71.7 mN/m and 35.1 mN/m of the pure substance (each value measured at 20 °C).
- Executive summary:
The surface tension of the saturated aqueous solution of the test item is 71.7 mN/m and 35.1 mN/m of the pure substance (each value measured at 20 °C).
Reference
Due to the very low water solubility of the substance no significant lowering of the surface tension has been expected. Thus, also the surface tension of the pure substance has been determined.
Description of key information
Not surface active (surface tension of saturated aqueous solution: 71.7 mN/m at 20°C
Key value for chemical safety assessment
- Surface tension:
- 71.7
- in mN/m at 20°C and concentration in mg/L:
- 0.05
Additional information
The surface tension of the saturated aqueous solution (water solubility < 0.05 mg/L) of the test item was determined according to the ring method (EU-method A5; GLP; RL1; Hüls, 1991) to be 71.7 mN/m at 20°C, i.e not significantly different from pure water. It is therefore not surface active. The surface tension of the pure substance according to the ring method amounted to 35.1 mN/m at 20 °C.
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).
