Working of emulsifying agents

For stabilisation of emulsion, they form an interfacial film between suspended particles and medium decreasing the interfacial tension between two liquids that form the emulsion. Long-chain molecules with polar groups are emulsifiers.

Examples

Examples of emulsifiers are milk, protein and soap.
