EMULSION CLEANING is an industrial cleaning process that uses an organic solvent as the main active agent. The solvent is usually a hydrocarbon of distilled petroleum dispersed in water. The emulsion, which alone is potentially volatile, is suspended in a nonvolatile aqueous vehicle. Most emulsion cleaners include emulsifying agents, and some are aided by surfactants. Emulsion cleaners are generally used in situations where alkaline or acid cleaners are not applicable. Emulsion means tiny droplets dispersed in large droplets. An emulsion is simply a colloidal suspension of one liquid into another immiscible liquid. (Immiscible means the liquids will not mix.) The oil-in-water emulsion has tiny droplets of an organic (hydrocarbon) solvent dispersed throughout a water solution. This is generally the type used in emulsion cleaning. The other is water-in-oil (natural petroleum), which has tiny droplets of a water solution dispersed throughout an oil. The oil-in-water type can easily be washed off with water and light detergent. The water-in-oil type leaves a greasy film that is much more difficult to remove. The hydrocarbon can be distilled from any of any of different petroleum products, such as naphtha, kerosine, benzene, carbon tetrachloride, or other chlorinated solvents, including 1,1,1-trichloroethane. Most of these are no longer used because they are flammable and potentially carcinogenic and have been identified as causes of ozone depletion. Most emulsions are now based on a “mineral spirits” derivative, a hydrocarbon mixture with a relatively high boiling point (93 to 150 °C, or 200 to 300 °F). Compositions, operating temperatures, and production applications for emulsion cleaners are summarized in Tables and .
