- 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.
