✦ Synopsis

close contact for a sufficient time can coalesce if the interfacial film does not completely inhibit diffusion of the dispersed phase; the rate of coarsening will depend both on the emulsifying agent and on the particular liquid concerned.

Conclusion

This suggested mechanism can account for many observations on emulsion stability and is independent of the particular nature of the interfacial film, i.e., whether it is ionic or non-ionic, unimolecular or multimolecular in thickness, viscous or rigid, soluble or insoluble. It is interesting that, although the diffusion of molecules of an emulsified liquid through the interfacial film does not appear to have received previous attention in relation to emulsion stability, it is an integral feature of Harkins' theory of emulsion p~lymerization.~
