  • Dispersant Wikipedia

    A dispersant or a dispersing agent is a substance, typically a surfactant, that is added to a suspension of solid or liquid particles in a liquid (such as a colloid or emulsion) to improve the separation of the particles and to prevent their settling or clumping. Dispersants are widely used to stabilize all kinds of industrial and artisanal products, such as paints, ferrofluids, and salad dressings.
