How do emulsifiers stabilise emulsion ? Name two emulsifiers.

Explanation

### Step-by-Step Solution:

1. **Definition of Emulsifiers**: Emulsifiers are substances that are added to stabilize emulsions. They help in mixing two immiscible liquids, such as oil and water, by reducing the surface tension at the interface between the two liquids.

2. **Types of Emulsifiers**: There are various types of emulsifiers. Two common examples include:
- **Soap**: Soap molecules have both a non-polar (hydrophobic) part and a polar (hydrophilic) part. This dual nature allows soap to interact with both oil and water.
- **Lyophilic Colloids**: These include substances like proteins and gums, which can stabilize emulsions by forming a protective layer around dispersed droplets.
