PPT-EMULSIONS

Emulsions Definition It is thermodynamically unstable system consisting of at least two immiscible one of them is finely subdivided and uniformly distributed as droplets throughout the other liquid phases one of which is dispersed as. “Water and oil don’t mix.”. “Water and . o. il . d. on’t mix” – at a microscopic level. Water is polar.. Oil often contains one polar end and one non-polar end.. It is favorable to organize the molecules such that the polar water molecules are interacting with the polar ends of the oil, and not the non-polar ends..

It is favorable to organize the molecules such that the polar water molecules are interacting with the polar ends of the oil, and not the non-polar ends.. Mr Powell 2013. Syllabus.... C1.6 Plant oils and their uses. Many plants produce useful oils that can be converted into consumer products including processed foods. Emulsions can be made and have a number of uses. Vegetable oils can be hardened to make margarine. Biodiesel fuel can be produced from vegetable oils.. The aqueous phase may consist of water soluble drugs, preservatives coloring and flavoring agents. It is desirable to use distill or deionized water, since calcium and magnesium ions found in hard water can have an adverse effect on the stability of some emulsions, particularly those containing fatty acid soaps as the emulsifying agents. angle . scattering . techniques. . .
