Colloidal silica is a mixture of a liquid and silica particles. It is a colloid, not a solution. In a solution, the solvent (such as water) breaks the "active ingredient" down to individual molecules. A colloid has larger particles, solids, that stay suspended in the liquid, carried by it but not broken down by it. Milk is a colloid.
