EMUSIFYING WAX
These are wax like solids with emulsifying properties. They are chiefly used in the preparation of ointments and creams. They include Emulsifying wax B.P.(ANIONIC), Cetomacrogal Emulsifying wax B.P. (NON-IONIC) and Cetrimide emulsifying wax B.P.(CATIONIC).

COMPOSITION of EMUSIFYING WAX (Anionic Emulsifying Wax)
Emulsifying wax B.P. (Anionic)Formula1. Cetostearyl alcohol ---- --90 g.2. Sodium Lauryl sulfate ---10g3. Distilled water -------- -----4ml
METHODMelt the cetostearyl alcohol and heat to 95⁰Celsius.add Sodium Lauryl sulfate (SLS). Mix them thoroughly and finally add distilled water. Heat to 115 o C. stirring vigorously until frothing cease and product is translucent cool quickly.USESIt is used as an emulsifying agent in the preparation of oil in water creams. Such creams are stable over a wide pH range and suitable for the incorporation of anionic and non-ionic medicaments.
