How to Refill Foaming Hand Soap Dispenser

Foaming hand soap refill recipe using just three, natural ingredients.
  1. Start by filling your foaming hand soap dispenser 4/5’s of the way full with water.
  2. Next, fill the rest of the dispenser ALMOST to the top with liquid Castile soap, leaving room for a small amount of vegetable glycerin.
  3. The addition of vegetable glycerin will ensure that your foaming hand soap isn’t too drying, but if you don’t have any on hand you can try substituting with other household kitchen oils. I sometimes use avocado oil which is doesn’t work as well as vegetable glycerin but it still gets the job done.
  4. Add a few drops of your favorite essential oil for scent.
  5. Lastly, shake and set by the sink for your family and guests to enjoy!

Is Foaming Soap Better than Liquid Soap?

Foaming soap vs liquid soap, which is better? There are pros and cons to each hand soap option so let’s discuss.


DIY foaming hand soap is the least expensive hand soap option I have found. Because the ingredients (aside from water) are used sparingly, you can continue to refill your foaming hand soap multiple times before stocking up on more. This is an easy money-saver.


According to a report in the American Journal of Infection Control, liquid hand soap is more effective at killing bacteria than foaming hand soap (source: Today). There are likely 2 reasons for this. 

First, people washing hands with liquid soap build a lather in the process of rubbing their hands together. Foaming soap is dispensed in a lather so that foaming reaction is lesser when washing with foaming hand soap. 

Second, there is simply much less soap in foaming soap recipes than there is in straight liquid soap. So if you’re a true germaphobe then this might be something to consider!


DIY foaming hand soap wins this category. Ingredients like soap and vegetable glycerine can be purchased in bulk. Because they are used sparingly in foaming hand soap, these bulk ingredients will last a much longer time than liquid soap would in a hand soap dispenser.
