Swirl to mix. By adding the soap after the water, you won't end up with a lot of bubbles at the top. Fill the rest of the dispenser with water, leaving a little space at the top of the container for the pump. Screw on the lid/pump and shake. Pump the dispenser a few times to get the foaming started.
Soap. Introduction: Soap is a mixture of sodium salts of various naturally occurring fatty acids. Air bubbles added to a molten soap will decrease the density of the soap and thus it will float on water. If the fatty acid salt has potassium rather than sodium, a softer lather is the result. Soap is produced by a saponification or basic hydrolysis reaction of a fat or oil. Currently, sodium carbonate or sodium hydroxide is used to neutralize the fatty acid and convert it to the salt.
