Emulsions and their types
Emulsion An emulsion is a system of two immiscible liquids which is thermodynamically unstable, in which one phase of liquid is dispersed as a globule in the other. In an emulsion, there are two phases. Continuous Phase It is the outer and continuous phase of the emulsion. Dispersed Phase This phase is dispersed in the form of globules in a continuous medium. Types of Emulsions There are four types of emulsions. Oil in water emulsion Water in animals in Multiple emission Microemulsions Oil in Water Emulsions In this type of emulsion droplets of oil are dispersed in water or an aqueous phase. The emulsion in which the internal phase is oily and the external phase is aqueous. majority of the orally administered emulsions are oil-in-water emulsions. e.g Milk is a natural oil in water emulsion, Emulsified creams and lotions are oil in water or water in oil emulsion depending on their use. Water in Oil Emulsions That type of emulsion in which the aqueo
