11 Questions
How is the emulsion type determined by the solubility of the emulsifying agent?
If the emulsifying agent is more soluble in water, an o/w emulsion will be formed
What is the primary function of emulsifying agents?
Reducing interfacial tension and maintaining dispersion stability
Which type of emulsion will be formed if the emulsifying agent is more soluble in oil?
W/O emulsion
What makes acacia a suitable emulsifying agent for oral emulsions?
Forms a thick film at the oil-water interface to act as a barrier to coalescence
What is a characteristic of naturally occurring emulsifying agents?
Susceptible to microbial contamination
What is the primary role of emulsifying agents in the production of a stable dispersion?
Reducing the droplet size
Which type of emulsion will be formed if the emulsifying agent is more soluble in water?
Oil-in-water (o/w) emulsion
What is the primary function of a naturally occurring emulsifying agent?
Creates a thick film at the oil-water interface
What are the primary components of effective emulsifying agents?
Hydrophilic polar groups and lipophilic non-polar groups
What is the role of emulsifying agents in the production of a stable dispersion?
Reducing interfacial tension and forming a barrier at the interface
Why are naturally occurring emulsifying agents susceptible to microbial contamination?
As they come from animal or vegetable sources
