In contrast, w/o emulsions make up oil-based products like sunscreen and most makeup. And homogenized milk is simply formed from the dispersal of fat droplets in an aqueous layer. O/w emulsions are the basis of water-based products in the pharmaceutical industry, they can be found in creams like moisturizers and topical steroid products. The chemical nature of an o/w emulsion is distinct from that of a w/o emulsion as such, each is most effectively used in different products. Get more tips on how to create better and more stable emulsions by reading here! Smaller droplet sizes will enhance the effectiveness of either system this may translate to increased bioavailability in pharmaceutical products or extended shelf life in food/beverage products. O/w emulsions are comprised of oil droplets suspended in an aqueous phase, while w/o emulsions are the opposite- water droplets suspended in a continuous oil phase. Oil and water are normally immiscible, but with proper mixing and stability agents, a permanent mixture, or emulsion, can be achieved. Perhaps the most basic, but also the most significant, difference between o/w and w/o emulsions is which phase is suspended and which is continuous. Read below for 3 specific differences between w/o and o/w emulsions. Regardless of the fact that both types are majorly made up of the same two compounds, each is distinct in its chemical properties, applications, and more having an understanding of these differences will help you make a more informed selection for your own application. Each of these products contains either a water-in-oil (w/o) or oil-in-water (o/w) emulsion. Emulsions are well-known systems within the pharmaceutical, biotechnology, and food industries for the properties that allow them to comprise numerous consumer products. ![]()
