What is the Difference Between Dispersant and Surfactant?

The main difference between dispersants and surfactants lies in their function and use. Here is a summary of their differences:

• Function: Surfactants lower the surface tension of a liquid to allow mixing and dispersion with other components, while dispersants are used specifically to disperse solid particles in a liquid and prevent them from aggregating or settling.
• Classification: A dispersant is a specific type of surfactant used to disperse particles or droplets in a liquid medium. Not all surfactants are dispersants, as surfactants can also act as detergents, wetting agents, emulsifiers, and foaming agents.
• Mechanism: Dispersants work by coating solid particles, reducing the attractive force between particles or droplets, preventing them from clumping together, and spreading them evenly throughout the liquid. Surfactants work by reducing the surface tension between two phases of matter, such as between two liquids, a gas and a liquid, or a liquid and a solid.

In summary, surfactants are a class of compounds that help substances mix together, while dispersants are a specific type of surfactant used to disperse particles or droplets in a liquid medium.
