![]() Furthermore, all emulsions require an emulsifier to stabilize the emulsion. Manufacturers use these emulsions for the production of creams and other oily moisturizers. Moreover, the chemical nature of oil in water emulsions makes it very important in the production of water-based pharmaceutical products. It increases the bioavailability of pharmaceutical products, and it also increases the shelf life of food and beverages. The effectiveness of this system enhances with a small size of dispersed oil droplets. But with proper mixing and using stabilizing agents, we can obtain oil in water emulsion. Oil does not mix with water under normal conditions. Therefore water acts as the continuous phase of this colloid while oil is the dispersed phase. Oil in water emulsions are colloidal systems that have oil droplets dispersed throughout the water. Side by Side Comparison – Oil in Water vs Water in Oil Emulsion in Tabular Formĥ. In addition to the above key difference, another important difference between oil in water and water in oil emulsions is that oil in water emulsions are useful in the production of water-based products while water in oil emulsions are useful in the production of oil-based products in the pharmaceutical industry. The difference between emulsions and other forms of colloids is that the dispersed and continuous phases of the emulsion are essentially liquids. Another main difference between oil in water and water in oil emulsion is that to achieve the stability of water in oil emulsions, it requires two or more emulsifiers, but to achieve the stability of oil in water emulsions, it requires only one emulsifier.Īn emulsion is a mixture of two or more substances that are usually immiscible. The key difference between oil in water and water in oil emulsion is that oil in water emulsions have oil droplets suspended in water whereas water in oil emulsions have water droplets suspended in oil.
