Emulsion is water-based paint, with vinyl or acrylic resins added to make the finish hardwearing. This results in varying degrees of sheen – generally, the shinier the finish, the tougher the paint. Use for interior walls and ceilings. Emulsion is used for encapsulating nutraceutical via spray drying. Emulsion is formed by applying mechanical force to oil and water mixture for disrupting liquid droplets into micronized droplets. Emulsifiers and stabilizers are needed for food emulsion.
