Applicant's summary and conclusion
- Conclusions:
- N-Propyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide is classified as not surface active in a concentration of 1.00 g/L.
- Executive summary:
The surface tension of an aqueous solution of N-Propyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide was determined as 71.99 ± 0.11 mN/m at 19.9 °C. One measurement was performed for verification (after 61 minutes). No significant changes and thus no significant dependence on time were observed.
As these values were higher than 60 mN/m, N-Propyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide was classified as not surface active.
The surface tension of the negative control lay within the accepted range.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
