摘要：

Liquid paraffin emulsion stabilized by the mixed emulsifier sodium dodecyl sulfate/cetyl alcohol have been examined by microscopy, particle size analysis, continuous shear rheometry, and creep. The disperse phase was aggregated and included some nonspherical globules containing crystals of cetyl alcohol. Emulsions were thixotropic and the extent increased with emulsifier concentration. In creep, systems suggested a mechanical model of three Voigt units in series with a Maxwell unit; the compliances decreased and the viscosities increased with emulsifier concentration. Rheological properties are explained by the presence of a viscoelastic network in the continuous phase. © 1968.
