- 40.3 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
Any other information on results incl. tables
0.09985 g and 0.10031 g of test material were used to prepare 100 mL of 1 g/L test solutions using HLPC grade water. Suspension was obtained after 2 hours of ultrasonication. The suspensions were filtered through a 0.2 μm syringe filter. The final solutions were slightly cloudy and hence stable suspensions were suspected. As the formal water solubility testing was inconclusive 1 g/L suspensions were tested.
Applicant's summary and conclusion
- Conclusions:
- The surface tension of the substance was estimated through the ring method, as 40.3 mN/m.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
