What are flocculating agents used for?

• A. To increase viscosity
• B. To improve the physical stability of suspension
• C. To enhance taste
• D. To decrease drug solubility

Answer: (B)

Flocculation improves the physical stability of suspensions by making particles form loose aggregates that settle quickly but can be easily redispersed. Flocculating agents achieve this by reducing repulsion between particles or by bridging them with polymer chains, so the particles come together into flocs rather than forming a hard compact sediment. This easy redispersion and prevention of hard cake keeps the suspension stable during storage and use. They’re not primarily used to raise viscosity, alter taste, or deliberately decrease solubility.
