Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key result
Surface tension:
52 mN/m
Temp.:
20 °C
Conc.:
90 other: saturated solution of test item in water (from a loading rate of nominally1.1 g/L)

Applicant's summary and conclusion

Conclusions:
The surface tension of a 90% saturated solution of test item in water (from a loading rate of nominally 1.1 g/L) has been determined to be 52.0 mN/m at 20.0 ± 0.5 °C.
The test item was considered to be surface-active.
Executive summary:

Surface Tension. 52.0 mN/m at 20.0 ± 0.5 °C for a 90 % saturated solution of test item in water (from a loading rate of nominally1.1 g/L), by a ring method, using a procedure designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for the Testing of Chemicals, 27 July 1995. The test item was considered to be surface-active.
