Preparation of Dusting Powder

Aim: To prepare and submit 100 gm of Dusting powder. 

Requirements: Magnesium carbonate, Light magnesium oxide, Talc, Zinc oxide, Zinc separate, Butter paper, Analytical balance, etc. 

Theory: Dusting powder is used externally for local application, not intended for systemic action. Dusting powders are homogenous, non-irritable, free flow, and have good spreadability and adsorption capacity. Dusting powder always should be dispersed in a very fine state of subdivision to enhance effectiveness and minimize irritation.
