10 Questions
What type of emulsions do emulsifying agents with a greater hydrophilic character tend to promote?
Oil-in-water emulsions
According to the Plastic or Interfacial Film Theory, where do emulsifying agents position themselves?
Between immiscible liquids
What property of the emulsifying agent determines whether oil-in-water or water-in-oil emulsions are formed?
Solubility in the two phases
In which phase does the emulsifier with higher solubility become the continuous phase of the emulsion?
Continuous phase
What effect does a greater hydrophobic character of an emulsifying agent have on emulsions?
Promotes water-in-oil emulsions
What is the main function of emulsifying agents in the Surface Tension Theory of emulsification?
Reduce interfacial tension
According to the Surface Tension Theory, what shape do all liquids tend to form to minimize their surface area?
Spherical
In the Oriented-Wedge Theory, where do emulsifying agents orient themselves around the droplets?
Around the droplets
What role does surface tension play in resisting the formation of smaller droplets in emulsification?
It reduces the attractive forces between liquids
How does the Oriented-Wedge Theory explain the orientation of emulsifying agents in immiscible liquids?
They are preferentially soluble in one phase
Explore various theories of emulsification such as the Surface Tension Theory which explains how emulsifying agents reduce interfacial tension between immiscible liquids. Learn about the forces involved in the formation of emulsions.
