Two main types are oil-in-water (O/W) and water-in-oil (W/O). In O/W, oil droplets are dispersed in a
Emulsifiers lower interfacial tension and create a stabilizing barrier. Common options include nonionic or anionic surfactants,
Production methods include high-shear mixing, rotor–stator devices, high-pressure homogenization, and ultrasonic emulsification. Choice of method and
Applications include cosmetics (creams and lotions), foods (dressings, dairy emulsions, spreads), pharmaceuticals, and industrial uses such
