Cleaning and Polishing Emulsions

In the application of emulsions for cleaning and polishing, a water phase and an oil phase (a selected halogenated solvent) are needed. The emulsions are used in cleaning and polishing the surfaces of metals and other hard surfaces (glass, etc.). 

For cleaning grease from metal surfaces, a strong alkali media (soda ash, borax, or alkali phosphates or silicates) are needed. However, these alone cannot effectively remove baked-on grease from metal surfaces. However, mixtures of soda and emulsifiers are found to be effective.
