Different formulation procedures include high shear homogenization and ultrasound, solvent emulsification/evaporation, or microemulsion. Egg lecithin has emulsification and lubricant properties, and is a surfactant. Lecithins have emulsification and lubricant properties, and are a surfactant. These products might also have surfactants to improve emulsification and spreading in the foaming medium. The three main processes involved in the scouring are saponification, emulsification and detergency. This balance has an important impact on wetting detergency, foam, solubility, emulsification. This viscous emulsification greatly complicated the cleanup efforts. Materials may be botanical, animal-derived, or metallic; processes include decoction, emulsification, calcination and fermentation. Wastewater purification of oils and contaminants by electrochemical emulsification is actively in research and development. Liquid-liquid phase separation presents the same drawbacks of emulsification/freeze-drying. Soy protein is used for emulsification and texturizing. Bulk emulsification methods are still relevant, though, since not all applications require uniform microparticles. The nucleus emulsification makes it easier to aspirate the particles. The glass beads were studied for their potential to stabilize emulsification processes. It is crucial that offset ink resist water-in-ink emulsification (e.g. repel rather than absorb water).
