Zusammenfassung
The authors consider the antagonistic salt PPh4Cl as a hydrotrope. Surface tension measurements and solubilization expts. on a hydrophobic dye confirm the solubilization behavior of PPh4Cl, which is in-between the one of SDS and SXS. With the help of scattering techniques (DLS, SLS, SAXS), NMR and cond. measurements, we show that in contrast to SDS as a hydrotrope with an inherent CMC, PPh4Cl ...

The authors consider the antagonistic salt PPh4Cl as a hydrotrope. Surface tension measurements and solubilization expts. on a hydrophobic dye confirm the solubilization behavior of PPh4Cl, which is in-between the one of SDS and SXS. With the help of scattering techniques (DLS, SLS, SAXS), NMR and cond. measurements, we show that in contrast to SDS as a hydrotrope with an inherent CMC, PPh4Cl does not exhibit mesoscale aggregation. Therefore, PPh4Cl can be classified rather as a hydrotrope in the modern sense, with an inherent MHC just as SXS.
