When oil is dispersed in the form of droplets in water in the presence of a suitable surfactant, oil-in-water (O/W) emulsions are formed. They have unique chemical properties covering a wide range of applications from environmental technologies to foodstuffs. In this book, authors discuss the preparation of O/W emulsions and their implications in environmental and food problems, covering hot topics including the composition and spill behavior of diluted bitumens, the use of O/W emulsions as platforms for the synthesis of waterborne particles, new methods to separate oil from water in oily...
