| Also Known As | Hydrophilic sol, lyophilic colloid (older term), water-loving colloid, stabilised colloidal dispersion |
What is Hydrophilic Colloids?
Colloidal dispersions in which the dispersed phase has a strong affinity for water. Hydrophilic colloids are stabilized by their interaction with water molecules. Examples include protein solutions, starch, and gelatin. They are important in food science and biological systems.

Colloidal dispersions in which the dispersed phase has a strong affinity for water. Hydrophilic colloids are stabilized by their interaction with water molecules. Examples include protein solutions, starch, and gelatin. They are important in food science and biological systems.
Hydrophilic colloids are used in: food thickeners and gels (pectin, gelatin, starch), pharmaceutical suspensions and emulsions, ink jet printing fluids, protective colloids in emulsion polymerisation (gelatin in photography), and biological systems (blood as a colloidal system).
No unique safety concerns compared to the hydrophilic substances themselves. Some protein-based hydrophilic colloids (latex proteins, gelatin from animal sources) are potent allergens. Microbiological contamination of aqueous hydrophilic colloidal systems can pose health hazards if used in food or p…
