How to Make Foaming Hand Soap at Home

This D.I.Y. post to make your own foaming hand soap at home may contain affiliate links.

Have you ever looked at the ingredients in store-bought hand soap? I bet if you have, you have no idea what they are, let along how safe they really are (or aren’t) for you. And finding a foaming hand soap that isn’t made with questionable chemicals isn’t easy or affordable.

Even the popular “safer’ brand Method includes sodium laurel sulfate as an ingredient which is classified as a toxin in some countries. We had resorted to non-foaming hand soap but I really prefer the foaming. It seems to wash off better.

I have come across “recipes” on the web to make soap, but frankly some things I just don’t have time to do, so the other day I tried an experiment. I took some of my Dr. Bronner’s castile soap, poured it into an old foaming hand soap dispenser, topped it off with water and voila!

It worked!

It foams, smells great and has ingredients that don’t scare me.

Make your own foaming hand soap at home - it's easy!

How to Make Foaming Hand Soap

What you need:


Empty foaming hand soap bottle. I bought one for $1.50, pouring the soap out, rinsed it until the water ran clear, then let it dry.

Dr. Bronner’s Castile soap. You can buy this online at Amazon.com, at Target stores, Meijer, and numerous other places online. It seems pricey but it’s concentrated. A little bit goes a long way. My 32oz bottle lasts a few months and I use it for everything. I even refill kitchen sprays and shampoo with it.

How to make:

Fill bottle a little less than 1/4 full of Dr. Bronner’s soap. Fill the remainder with water. It takes a few pumps to build up the pressure, but it works great! I do find the soap settles a bit so I do shake it up every once in awhile. Not sure I need to, but I do it anyway.

    I am definitely going to try this, maybe it won’t dry my hands out as bad and make them crack. I clean like a maniac and hate germs so wash constantly. Thanks!

    This is what I do as well! Love Dr. Bronner’s and it seemed a natural progression.

    My next project will be moving off products with paraben – oy!

      It’s so simply but works. I clean my floors with it, wash kitchen counters with it. I wash my hair with it. Any situation I need soap I use it. I don’t use it in the dishwasher or washing machine though because the quantities are critical there and I don’t want to break the machines.
