- Specific details on test material used for the study:
- Name: FSM-005W
Batch/Lot Number: 170321
CAS No.: 2601-33-4
Description: Colourless liquid
Purity: 19.9%
Expiry date: 20 November 2018
Storage conditions: Refrigerated and protected from light - Surface tension:
- 32.6 mN/m
- Temp.:
- 21 °C
- Conc.:
- 1.01 g/L
- Conclusions:
- The determination of the surface tension was carried out on the test item, with the use of a Krüss K11 Tensiometer by ring method. The value was found to be 32.6 mN/m at 21°C ± 0.5°C.
As the surface tension value was lower than 60 mN/m, FSM-005W is classified as surface active. - Executive summary:
The determination of the surface tension was carried out on the test item, with the use of a Krüss K11 Tensiometer by ring method. The value was found to be 32.6 mN/m at 21°C ± 0.5°C, in accordance with Method A.5. “Surface Tension”, Official Journal of the European Union L 142 of 31 May 2008, and OECD Guidelines for Testing of Chemicals, Guideline No. 115, ”Surface Tension of Aqueous Solutions”, adopted 27 July 1995.
Reference
The surface tension of the test item aqueous solution read on the instrument was 32.0 mN/m at 21°C ± 0.5°C using the ring method representing the mean of five
separate measurements. The measured values were corrected with Harkins-Jordan correction factor.
The measured surface tension was multiplied by Φb resulting in a corrected surface tension of 32.6 mN/m.
As the surface tension value was lower than 60 mN/m, FSM-005W is classified as surface active.
Measured surface tension values and equilibrium times
| Surface tension (mN/m) | Time (sec) |
| 32.03 | 420 |
| 32.02 | 444 |
| 32.02 | 468 |
| 32.01 | 492 |
