Emulsifying agent: Definition, Classification, Types, HLB Scale

Emulsifying agent: Definition, Classification, Types, HLB Scale


What is the definition of emulsifying agent? OR what is an emulsifying agent?

The emulsifying agent is a surface-active substance to make an emulsion, which is both fat and water-soluble. It helps the dispersed phase to uniformly be dispersed in the continuous phase.

What is the example emulsifying agent in pharmacy?

Acacia, Tragacanth is naturally occurring while synthetic include Polysorbate 20, Polysorbate 80, Sodium lauryl sulfate(SLS), Sorbitan laurate, Sorbitan stearate

Name any two emulsifying agents?

Polysorbate 20, Polysorbate 80, Sodium lauryl sulfate(SLS), Sorbitan laurate, Sorbitan stearate

Name natural emulsifying agent?

Acacia, Tragacanth

Which emulsifying agent is added in the emulsion test?

We can add Natural as well as synthetic emulsifying agents can be used in the emulsion test based on which type of emulsion we are using for the test

What is the emulsifying agent used in milk?

Casein (an emulsifying agent) is a protein containing phosphate groups. The primary emulsifying agent in dairy emulsions is the proteins (i.e. caseins, in either monomeric or micellar form).

Classification of Emulsifying agent

1. Natural emulsifying agents:

  • Vegetable sources- Agar, Tragacanth, Gum acacia, etc.
  • Animal sources- Wool fat, Gelatin, etc.

2. Semi-synthetic emulsifying agents: Methylcellulose, Sodium CMC, etc.
3. Synthetic emulsifying agents:

  • Anionic emulsifying agents: Sodium lauryl sulfate(SLS)
  • Cationic emulsifying agents: Benzalkonium Chloride
  • Non-ionic emulsifying agents: Glyceryl ester
  • Inorganic emulsifying agents: Milk of magnesia
