- 72.38 mN/m
- Temp.:
- 20 °C
- Conc.:
- 42.8 mg/L
Applicant's summary and conclusion
- Conclusions:
- The surface tension value was found to be 72.38 mN/m with 0.14 RSD% at 20°C ± 0.2°C. As the surface tension value of the aqueous solution of the test item (at 90% of saturated level) was greater than 60 mN/m, S194997 is classified as not being a surface active substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
