WebJan 1, 2009 · The effectiveness of the emulsifying agent is related to the minimum amount of it that is required to generate and stabilize small droplets during homogenization. A useful quantity in this context is the surface load, i.e., the mass of emulsifying agent per unit area of oil–water interface (typically a few mg m − 2). Web8. Which of the following statement about emulsions is true? a) Oily drugs cannot be prepared in the form of emulsions. b) Digestion does not involve the process of emulsification. c) Disinfectants like Dettol and Lysol give emulsions of water-in-oil type on mixing with water. d) The cleansing action of soap is based upon the formation of water ...
