The oil globules adsorbed to the cloud particles stabilize the suspension by decreasing the average density of particles to bring it closer to that of the serum. However, large amounts of oil can be problematic as they cause complete breakdown of suspensions by causing cloud particles to float to the surface. The particles in the cloud have a negative charge that decreases with decreasing pH. In accordance with cloud stability, the hydration of particles is more significant than their electrical charge.
