A novel solid particle emulsifier was synthesized by the self?assembly of paraffin wax and β?cyclodextrin (β?CD ) . The synthesized product was characterized by Fourier transform infrared spectroscopy ( FT?IR) and thermo gravimetric analysis ( TGA) , and was applied to emulsify silicone oil with long chain alkyl group. The morphology and size of the dispersed droplets were characterized by the optical microscopy ( OM) and particle size analyzer. The heat resistance, acid and alkali resistance as well as the electrolyte resistance of the emulsion were investigated. Results indicated that dispersed droplets exhibited uniform sphere, together with an emulsion layer of mean diameter of 43?5μm when the self?assembly was carried out on paraffin wax to β?CD mass ratio of 1∶8 and the mass ratio of the self?assembled particles to long chain alkyl silicone oil was 50%. The tolerance tests of the emulsion demonstrated that its heat resistance increased greatly with the increase in the melting point of paraffin wax. The stability of the emulsion under acid condition was superior to that under alkaline condition. The emulsion exhibited excellent stability in electrolyte solution with lower concentration, but its stability would be subjected to different degrees of damage in concentrated electrolyte solutions.
