Paraffin emulsion was prepared from liquid paraffin by the means of adding coemulsifier. The effects of the emulsifie species and their dosages, water dosage, emulsifying temperature, and emulsifying time on the paraffin emulsion properties were studied. The results showed that composite emulsifiers could provide better performance for the paraffin emulsion. The influencing factors can be arranged in order：water dosage>emulsifier dosage>emulsifying temperature>emulsifying time. Stable paraffin emulsion can be prepared under the optimum conditions：m(glycerol monostearate)/m(Tween80)=3∶4, emulsifier dosage 0.9％，emulsifying temperature 85 ℃，emulsifying time 50 min，water dosage 62.0％ and stirring speed 1 100 r/min. The experimental result indicated that the liquid paraffinemulsion had better stability density and dispersibility.
