Optimization balances droplet size distribution, emulsifier chemistry, pH, water quality, and bitumen temperature to achieve storage stability without sacrificing field breaking behavior. Colloid mill speed and gap influence droplet size and stability. Breaking time is tuned by emulsifier type and concentration, soap solution pH, and additives. Formulation must match application method: sprayers need lower viscosity and stable pumping, while slurry and mixes may require different stability and break control for workability.
