The Influence of Bicomponent Mixed Surfactants on Drop/Interface Coalescence [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2004
Effects of binary mixtures of ionic/nonionic (sodium dodecyl sulfate/2-heptanol or 1-decanol) and nonionic/nonionic surfactants (2-heptnol/1-decanol) on drop/interface coalescence of water drops in a continuous n-heptane phase were examined.
