To overcome this natural tendency, an emulsifying agent is required. Even household cleaners utilize this technology, mixing grease-cutting oils with water to create sprays that effectively coat and clean surfaces without separating.
Everyday Examples Where Oil and Water Do Mix
Common food-grade examples include lecithin, found in egg yolks, which is responsible for the smooth texture of mayonnaise, and mustard, which contains natural emulsifiers that bind oil and vinegar. Paint manufacturers use emulsifiers to create water-based paints that contain oil pigments, allowing for easy cleanup with water while delivering the smooth finish of oil paints.
High-shear mixers use rapidly rotating blades to break one phase into tiny droplets while simultaneously dispersing them into the other. Methods for Creating Stable Mixtures Simply shaking oil and water with an emulsifier yields only a temporary blend.
