dispersing agent

In chemistry, a dispersant, also known as a dispersing agent, is a substance that promotes the formation and stabilization of a dispersion of one substance within another. These agents reduce the surface tension of a liquid, enhancing its spreading and wetting properties.12

Dispersing agents are crucial in various applications, such as in the manufacturing of coatings. Here, they are added to pigment dispersions to prevent particles from clumping together, ensuring they remain stable and independent throughout the production, storage, application, and film formation processes. They work by adsorbing onto pigment particles, creating a repulsive barrier that counteracts the natural attractive forces between them.3

While the term "dispersing agent" is primarily used in chemistry and materials science, the concept of dispersal also applies to biology, referring to the scattering of organisms. In biology, dispersal can occur through various agents like wind, water, or animals.45
