Emulsion Concept, Types and Techniques: A Review

The concept of emulsion is very important in many industries such as nutritional, pharmaceutical, cosmetics and life in general. Generally, emulsions are stabilized by emulsifiers, which do not only confer stability on the products but also nutrition, aesthetics, and durability. While creating an emulsion from two separate immiscible liquids and with respect to the desired type, it is also important to note that the best emulsification techniques must be applied. This review therefore summarizes the concept of emulsions, and presents a critical discussion of their types and preparation techniques. Moreover, insights into the strategic approach for optimizing emulsion preparation techniques for meaningful practical applications are provided. It is therefore expected that this review will be of significant impact in the development of new emulsions for industrial applications.
