摘要

The theory of emulsions and emulsifying agents is a mix of classical colloid chemistry and a development of the ancient technology involved in the production of commercial emulsions. Thus the term emulsifiers refer to both a chemical entity and machinery and in reference to these same machines. The term homogenizer is often applied to what is properly a colloid mill.Appearance, texture, and stability of an emulsion depend on its ingredients and its preparation. There are several tools to make an emulsion. Higher the force, smaller the droplets in the emulsion and more stable will be the emulsionStability. In any emulsion preparation, series of trails should be conducted to select a proper surfactant system. Each surfactant has a specific HLB (hydrophilic liphophilic balance) system. Likewise, each oil has a specific HLB. If the required HLB for an oil is known, select surfactants or surfactant blends with HLB numbers close to the required HLB should be selected. Different surfactants with the required HLB number should be examined. Not all surfactants having the same HLB value can be used.
