Dispersant Agent or dispersing agent is a substance that is usually added to a suspension of solid or liquid particles in a liquid (such as a colloid or emulsion) to improve particle separation and prevent settling or clumping.
Dispersant Agents are widely used to stabilize various industrial and artisanal products, such as paint and ferrofluid. It is also commonly used to bring oily contamination into aqueous suspension, and emulsifiers, which are used to create homogeneous mixtures of immiscible liquids such as water and oil. Natural suspensions such as milk and latex contain substances that function as dispersants.
