Emulsions are normally prepared by shaking the two components together vigorously although some kind of emulsifying agent usually has to added to stabilize the product. This emulsifying agent may be a soap or other surfactant (surface active) species or a lyophilic sol. Emulsions are broadly classified into two types : (i) Oil in water emulsions (O/W): Oil acts as dispersed phase and water acts as dispersion medium (ii) Water in oil emulsions (W/O) : Water acts as dispersed phase and oil acts as dispersion medium. Dye test, dilution test may be employed for identification of emulsions. Read the two statements : A) Milk is an example of oil in water (O/W) type emulsion B) Cold cream is an example of water in oil (W/O) type emulsion
