Results and discussion
Surface tension
- Key result
- Surface tension:
- > 69.52 - <= 71.38 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
Applicant's summary and conclusion
- Conclusions:
- Values ranging from 69.52 mN/m to 71.38 mN/m were recorded showing no significant variations. The values of the single determinations show no significant difference (1.16 % between mean values of the two measurement series)
As the determined surface tension of Glutardialdehyde bis-Sodiumbisulfite was higher than 60 mN/m, the test item can be classified as not surface active.
