12/2/2023 0 Comments Emulsion surface chemistrySeveral various chemical and physical processes and mechanisms can be contained in the procedure of emulsification. This is also known as the Tyndall effect. If the emulsion is dilute, then higher-frequency and the low-wavelength type of light will be scattered in more fractions, and this type of emulsion will be converted to a blue color. Emulsions occur in white color when the light is dispersed in equal proportions.Emulsions have a cloudy presence due to so many phase interfaces scattering light moving through the emulsions.a continuous and the dispersed with the boundary coming in between the phases, that is called “interface”. Emulsions contain both immiscible liquid phases i.e.Read More: Study the role of emulsifying agents in stabilising the emulsions of different oils Some of the most common examples of emulsifiers are egg yolk, mustard, sodium phosphates, DATEM, Mono and diglycerides, cellulose, soy lecithin, etc.Some commonly used emulsifiers for the Water in oil emulsions are the long-chain alcohols, heavy metal salts of fatty acids, etc.The generally used emulsifiers for Oil in water emulsions are proteins, gums, soaps, etc.On the other hand, if the emulsifier is more soluble in oil, then oil develops into the dispersion medium and water turns into the dispersed phase.If the emulsifier is more soluble in water then the water turn into the dispersion medium and oil is converted into the dispersed phase and hence we get oil in the water emulsion.It depends mainly on which amidst water and oil can solvate the emulsifier to a larger extent. It’s not just the percentage of water and oil that determines whether it is oil-in-water or a water-in-oil emulsion.Also, it can be cationic, anionic, or even non-polar. Emulsifiers build a layer between the dispersed phase and the dispersion medium, thereby preventing the dispersed phase particles to come into the league to build larger particles and separate.Emulsifier / Emulsifying agents are soluble in both water and oil.They are substances that have a hydrophilic end (polar) and a hydrophobic end (non-polar).The various attributes of emulsifiers are as follows: These are the materials which are added to emulsions for stabilization purpose.
