What is Dispersing Medium?
The continuous phase of a colloid in which the dispersed phase particles are distributed. Also called the dispersion medium. For example, water is the dispersing medium in milk, and air is the dispersing medium in fog.

The continuous phase of a colloid in which the dispersed phase particles are distributed. Also called the dispersion medium. For example, water is the dispersing medium in milk, and air is the dispersing medium in fog.
Choice of dispersing medium governs colloidal stability, delivery route (aqueous medium for IV drug delivery, oil medium for lipophilic drugs), and processing (aqueous vs. non-aqueous dispersions in paints, coatings, and inks).
The dispersing medium's chemical properties determine exposure routes and hazards of the colloidal system. Organic dispersing media (hexane, chloroform) are flammable or toxic. Aqueous dispersing media with dissolved electrolytes may affect colloidal stability (coagulation).
