DIY Foaming Hand Soap

I have a confession to make.  I have always hated those foaming soap dispensers that are ubiquitous in public restrooms.  To me, they are a watery, slimy mess that leaves hands feeling sticky and icky no matter how hard you work at rinsing after the fact.

That being said, I wanted an alternative to the Dirt Cheap Soft Soap that is crafted in my kitchen every month or two.  While not difficult to make, it does take some time and a bit of a mess.  Plus, as those of you that have tried it know, it sometimes takes a bit of tinkering to bring it to that just-perfect texture.

Thus started my exploration into making my own foaming hand soap.  I needed a benchmark so I started out by purchasing some Method Foaming Hand Soap from the local supermarket.  My thought was that I could then re-purpose the container to use when making my own DIY version.

Two things happened along the way.  First, I loved the foaming hand soap. It was not even remotely similar to the commercial stuff used in public places.  Second, repurposing the container after the fact was a total waste of time.  It started to fail early on and never did work right.

From there I was on a mission to make my own liquid foaming hand soap and let me tell you, there is now going to be no turning back. This stuff is fantastic.  It is rich and creamy and not at all slimy.  It smells heavenly and leaves my hands with a nice, smooth and moisturized feeling after the fact.  Plus, it is a cinch to make and there is no mess to clean up.

DIY Foaming Hand Soap (So Simple Anyone Can Make It)

If you are expecting a complicated recipe, look elsewhere because this is so easy peasy that I am browbeating myself not trying it sooner.  Plus, as you will learn below, it only costs about $1.10 for a large, 12 ounce bottle of the best darn hand soap you will ever use.


10 ounces of water (distilled or filtered water is best; I use Berkey water)
2 ounces liquid castile soap (I used Dr. Bronner’s)
8 to 10 drops of essential oil (optional)
Foaming Dispenser (I like this one)


Add the water to your dispenser.  Top with liquid castile soap and your essential oils if you are using them.  Give everything a good shake and you are good to go.

Note:  the ratio of castile soap to water is 1:5 so if your container is smaller or larger, you can adjust the amounts accordingly.

That is it.  Were your expecting something difficult?

Variations to Personalize Your Foaming Hand Soap

For the ultimate flexibility, use unscented liquid castile soap and add your own essential oils  This is an especially good solution when you want to mix up a variety of “flavors”.  Perhaps you want to use lemon, as an example, in the kitchen and tea tree (melaleuca) in the bathroom.  Or the other way around.  During the winter cold and flu season, you might want to add some oregano essential oil or even some Shield Protective Blend (a thieves-like blend) to add some extra protection to your wellness arsenal.

All that being said, soap would make an excellent use for your inexpensive oils since they are, after all, going down the drain.  Some may think making this statement is travesty but as far as I am concerned, it is what it is.

For my own use, I have chosen to purchase Dr. Bronner’s Liquid Castile Soap that is pre-scented.  Call me a sucker for those crazy hallucinogenic labels on the bottles, but I have the Lavender, Tea Tree, Hemp Rose, and Peppermint.

By the way, if you love the smell of Rose essential oil but not the price, try Geranium instead.  I like to use it in the diffuser at bedtime since it is so calming and puts me in the right frame of mind for sleeping.

DIY Means Saving Money

I ran some rough calculations on the cost of making your own liquid foaming hand soap.  I did not want to include the cost of the foamer (container) itself since the type you use is a matter of choice.

Using a quality foaming soap such as Method, I came up with $5.00 for a 28 ounce refill pouch (remember, I did not want to include the cost of the foaming dispenser which can run from free for a repurposed container to $10 or $20 depending on how fancy you want to get).  That works out to 17 cents an ounce, pre-diluted.  To fill a 12 ounce container, your cost will be $2.04.

Purchasing Dr, Bronners on Amazon is not the cheapest way to go but convenient.  At about $18 for a 32 ounce bottle, that works out to 56 cents an ounce.  To fill a 12 ounce container you only need two ounces at an outside cost of $1.12.

Don’t you just love to save money?  Plus, you can use your liquid castile soap for so many other things.

A Word About Foaming Dispenser

I hesitate to recommend one specific foaming dispenser over another. Making things difficult is that online reviews are all over the board.  Although using a repurposed foamer might sound like a good idea, my repurposed Method soap dispenser failed almost immediately.  I also tried some inexpensive travel-sized foaming dispensers, but of the three I ordered, two were DOA.

On the other hand, the foaming dispenser in the picture has been functioning for about three weeks and is a keeper as far as I am concerned.  Your mileage may vary.  

The Perfect Gift

This time of year we all have gift giving on the mind.  Let’s face it, some people are darn difficult to please.  Here is a suggestion: how about a bottle of liquid castile soap, a nice foamer bottle, and a fluffy hand towel?  Snuggle it all in a basket with some instructions for making the foaming hand soap and you are all set.

The Final Word

I have always sought out products that are both non-toxic and multi-purpose.  This includes personal products such as lotions, potions, and soaps in addition to household cleaners.  The thing is, over the years I have learned that some of the products I considered safe and natural were not.  For that reason I continue to study and educate myself and, when possible, make my own products.

In closing, I just want to remind you that as as preppers, we want to stock up on as few products as necessary to get the job done.  On my list are liquid castile soap, vinegar, club soda, and baking soda.  These items have a forever shelf life and, with the exception of the liquid castile soap, are dirt cheap.  And even the liquid castile soap, when diluted, is not a bad value.

Have fun making your own liquid foaming hand soap; once you start, you will never go back to buying pre-made hand soap at the store!

Enjoy your next adventure through common sense and thoughtful preparation!
