What cleaning method uses a solution to disperse two immiscible liquids?

Emulsification is the process that involves using a solution to disperse two immiscible liquids, such as oil and water. When an emulsifying agent is added, it allows these two substances to mix into a stable emulsion, which can then effectively combine elements that would otherwise separate. This method is crucial in various cleaning applications, particularly when dealing with biofilms or oily surgical equipment, as it enhances the ability of cleaning solutions to penetrate and remove contaminants.

In contrast, filtration refers to the process of removing solid particles from a liquid or gas by passing the mixture through a filter. Decontamination involves the overall reduction of pathogenic organisms from surfaces, and disinfection is the process of eliminating or killing most pathogens on surfaces, but it does not specifically target the mixing of immiscible liquids. Therefore, emulsification stands out as the correct method that pertains uniquely to the mixing of immiscible solutions.
