- Deflocculated Suspensions show slow sedimentation but form a hard cake, making redispersion difficult.
- Deflocculated Suspensions Particles remain separate and discrete.
- Settle slowly due to small size and mutual repulsion.
- Can lead to caking—a dense sediment forms that’s hard to redisperse.
Advantages of Deflocculated Suspensions:
- Appears more uniform
- Slower settling
Disadvantages of Deflocculated Suspensions:
- Risk of caking
- Poor redispersibility
Formulation Strategy:
| Component | Function |
| Wetting agent | Improves dispersion |
| Suspending agent | Maintains particles in suspension |
| Buffer | pH control |
| Preservative | Microbial protection |
| Vehicle | Dispersion medium |
No flocculating agent is used — particles are kept apart electrostatically or sterically.
