What are wetting agents for suspensions?

Wetting agents for suspensions are surfactants or additives that help reduce the surface tension between the liquid and solid particles, facilitating better dispersion of the solids within the liquid medium. By enhancing the wettability of the particles, these agents prevent agglomeration and sedimentation, ensuring a more stable and uniform suspension. Common examples include polysorbates and sodium lauryl sulfate. Their use is essential in various industries, including pharmaceuticals, cosmetics, and food.
