Upon completion of this exercise, you should be able to: Define and/or identify emulsions and emulsifying agents. Identify two factors that determine emulsion type (o/w vs. w/o). Describe the levels of instability to which emulsions are subject. Describe 3 mechanisms by which emulsions are stabilized. Classify emulsifying agents by type and ...
Feb 7, 2018 · An emulsion is a uniform mixture of two unmixable liquids like oil and water, using agitation from whisking or blending to create a uniform suspension. Depending on how the emulsion is formed, the agitation makes either small oil droplets or water/vinegar droplets. The droplets are called the “dispersed phase,” while the liquid surrounding ...
The meaning of EMULSIFY is to disperse in an emulsion; also : to convert (two or more immiscible liquids) into an emulsion. How to use emulsify in a sentence.
Emulsion. An emulsion is what you get when you put two or more liquids together and the two liquids do not mix. Immiscible liquids do not mix together. For example, if you add oil to water, the oil floats on the surface of the water. And if you shake the two together then leave them to stand, tiny droplets of oil float upwards.
In the melt emulsification method, the drug material is firstly dispersed in the aqueous solution with stabilizer. Then an emulsion was obtained after the solution was heated to a temperature above the melting point of the drug and homogenized. During this process, the emulsion was maintained at a temperature above the melting point of the drug.
The resulting emulsion droplets have high-energy bonds creating a very tight dispersion of droplets that is not easily separated. These surface-acting forces can create oil-in-water emulsions, water-in-oil emulsions, or both. Such emulsions require temperature and chemical treating in surface equipment to separate.
The emulsion is a word that originated from the Latin word “Mulgeo”, which means “To milk”. Milk is the best example of emulsion, consisting of biphasic liquid systems containing both fat and water. The emulsion can define as the colloidal system, which includes two or more phases of immiscible liquids.
