| These colloids are formed when small particles aggregates to form a particle having size in colloidal range | Some substances at low concentration behave as normal electrolytes, but at higher concentrations exhibit colloidal behaviour due to formation of aggregates. The aggregated particles are called micelles and are also known as associated colloids |
| Example: Gold sol | Example: Micelles |
