Nov 9, 2014 · This document provides an overview of pharmaceutical emulsions. It defines emulsions as dispersions of one liquid in another immiscible liquid, stabilized by an emulsifying agent. The key topics covered include the classification of emulsions as oil-in-water or water-in-oil, theories of emulsification, common emulsifying agents like surfactants ...
May 10, 2015 · It then discusses the internal and external phases of emulsions, types of emulsions based on dispersed phase and size, advantages and disadvantages, identification tests, emulsifying agents, theories of emulsification, and factors that contribute to emulsion stability like interfacial tension.
Jul 7, 2021 · 1) An emulsion is an unstable mixture of two immiscible liquids, where one liquid is dispersed as globules in the other liquid. Emulsions can be O/W (oil in water) or W/O (water in oil) types.
EMULSION An emulsion is liquid preparation containing two immiscible liquids, one of which is dispersed as globules (dispersed phase = internal phase) in the other liquid (continuous phase = external phase) that is stabilized by an emulsifying agent.
