- 66.9 - <= 68.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 9.87 g/L
- Remarks on result:
- other: Readings taken on a 9.87 g/l emulsion
Any other information on results incl. tables
Results of 59.4 to 59.7 mN/m, were obtained on the filtrate of a 10.08 g/l emulsion, prepared by hand (shaken), filtered and measured with a thermostat at 20 ° C in the filtrate.
Applicant's summary and conclusion
- Conclusions:
- The substance is not considered to be surface active based on measurements on the actual emulsion itself.
- Executive summary:
The substance is not considered to be surface active based on measurements on the actual emulsion itself.
No classification is applicable.
