colloidal stability

Colloidal stability refers to a mixture where tiny particles (smaller than a micron) are evenly dispersed within a fluid without clumping or settling out over time. Stability depends on the balance of forces: repulsive forces keep particles apart, preventing aggregation, while attractive forces can cause them to stick together. Factors like particle charge, surface coatings, temperature, and the presence of other substances influence stability. A stable colloid remains uniform and well-mixed, which is essential in products like medicines, foods, or paints to maintain their quality and performance.
