Definition - What does Lyophilic Colloid mean?
Lyophilic Colloid is a substance which contains molecules that dissolve completely in liquids. The term lyophilic is a combination of two words, i.e., “Lyo” which means solvent and “Philic” which means loving. When such colloids dissolve in liquids they form a very high attractive force between the liquid molecules and colloidal particles and the system readily becomes a stable solution.
Petropedia explains Lyophilic Colloid
As lyophilic colloidal particles mix completely with hydrocarbon liquids, lyophilic solutions are easy to prepare. All lyophilic solutions are generally very stable as they have a strong force of attraction between the colloidal particles and the liquid particles. Even if a small quantity of electrolyte is added in such solutions, they remain stable and do not form any kind of precipitate or coagulation. Lyophilic solutions are reversible in nature. Examples of lyophilic solutions are organic substances such as gelatin, gum, starch and proteins.
