Emulsifying Agent

Emulsifying Agent or Surface Active Agents:

 To reduce internal phase into small globules / Stabilizer of the droplet form of the internal phase of an emulsion. Emulsifiers are also used as a wetting agents & Surfactant.

Surface tension – Interfacial tension at an air liquid interface. Surface tension causes fluids to assume spherical shape.

For example:

- Egg yolk

-  Agar

-  Honey

-  Gelatin

-  Na Alginate

-  Polysorbate (80, 60, 20) 

-  Potassium oleate / Sodium dodecyl (lauryl) suphate 

-  Povidone 

-  Propylene glycol 

-  Theophylene / Propylene glycol / Ethyl alcohol / Glycerin.
