To produce a stable emulsion, an emulsifying agent can be added to the oil and water that will either act as a barrier to alter the droplet coalescence rate, or create an interfacial film that can produce repulsive electrical forces between approaching droplets.

Zeta Potential and Particle Size to Predict Emulsion Stability

Emulsions are popular vehicles in skin care due to their affinity for the skin; however, they are thermodynamically unstable systems. This study investigates zeta potential and particle size distribution as potential screening tools to predict instabilities in emulsion-based cosmetic products, to supplement regular accelerated stability testing.
