What is a water and oil emulsion?
This is simply a chemical method of overcoming the natural tendency of oil and water not to mix. In order to make this happen it takes small amounts of special emulsifying agents (that are like soaps) being added to a mixer that has water and oil in it, and then very vigorously mixing the ingredients until you have an emulsion that is quite stable and prevents the oil and water from separating. A common example of this is mayonnaise. In addition, our High Sierra is a water and oil emulsion. This is also done when an oil-based stain is converted into a water-based stain.
