A dispersant is a form of surfactant. However, not all surfactants are dispersants. A surfactant can act as a detergent, wetting agent, emulsifier, foaming agent in addition to acting as a dispersing agent. Usually both are organic compounds.

 What is a dispersant?
A dispersant is a liquid or gas used to disperse small particles in a medium. We also call it "plasticizers". There are two forms; surface-active polymers and surface-active substances. We add these substances to the suspension to prevent the formation of particle clusters. This improves particle separation to prevent clumping. In addition, this process prevents particles from settling. The dispersant usually consists of one or more surfactants.

Mechanism of dispersant action

What is a surfactant?
A surfactant is a substance that can reduce the surface tension between two phases of matter. It can reduce the surface tension between two fluids, between a gas and a liquid, or between a liquid and a solid. They are mostly amphiphilic organic compounds. This means that these substances contain both hydrophilic and hydrophobic regions in the same molecule. Therefore, they contain both water-soluble and water-insoluble regions.
