EC number: 947-907-6 | CAS number: -
The readings and temperatures for the sample solutions are shown in the following table:
Table1: Surface tension values
1.001 x 104
3.002 x 103
1.001 x 103
Mean surface tension values were based on the last three readings for a particular concentration which were considered to be constant.
Theconcentration (mg/L), log10 [concentration (mg/L)] and mean surface tension values for the sample solutions are shown in the following table:
Table 2: The concentration (mg/L), log10 [concentration (mg/L)] and mean surface tension values
Mean Surface Tension (mN/m)
The surface tension at 1 g/L was determined to be 41.0 ± 0.5mN/m.
A study was conducted to determine the surface tension of the test substance using the ring method, according to OECD Guideline 115 and EU Method A.5. Under the study conditions, the surface tension of 1 g/L nominal test concentration in water was determined to be 41 ± 0.5 mN/m at 20 ± 0.5ºC. Therefore, the test substance was considered to be surface-active (Envigo, 2018).
Surface tension of the test substance was determined using the ring method, according to OECD Guideline 115 and EU Method A.5 (Envigo, 2018).
