For this foaming hand soap recipe all you'll need is a special soap dispenser, liquid soap, essential oil(s) and distilled water.
Using a funnel pour the Pure-Castile Liquid Soap into a 15-ounce foaming soap dispenser. Then add the lemon essential oil and the basil essential oil along with the distilled water. If using food coloring add it here too. Then screw the pump onto the bottle, gently rock bottle back and forth to combine all ingredients and your new foaming hand soap is ready to use.
