DIY Foaming Hand Soap Recipe - all natural and frugal
Wellness Mama » Blog » Natural Home » DIY Foaming Hand Soap

I started making my own foaming hand soap pretty early in my switch to a more natural lifestyle. With concerns over antibacterial ingredients in many hand soaps and potty-training little ones who found the need to wash their hands/arms/the counter with soap a thousand times a day, I needed a healthy and frugal option.

Thankfully, there is a natural, homemade and incredibly simple option that works just as well and doesn’t cost $3.59 a bottle like the foaming versions at the store.

The recipe itself is literally so simple that I now have my six year old refill the bottles and it takes just seconds to make. I keep the few simple ingredients on hand and we never have to buy hand soap or worry about running out…Surprisingly, this foaming version also makes a decent shaving cream in the shower…

Before you begin, you’ll need a foaming hand soap container. I originally ordered this pretty but pricey foam dispenser online before I realized that  there was a much more frugal and inexpensive option: Buy a bottle of foaming hand soap, pour it out if it isn’t natural, and reuse after the soap is used up.

Materials

Instructions

  • Fill the soap dispenser with water to within about 1 inch of the top.
  • Add at least 2 tablespoons of liquid castile soap to the water mixture. NOTE: do not add the soap first or it will create bubbles when the water is added.
  • Add the oil and any essential oils if you are using them.
  • Close and lightly swish to mix.
  • Use as you would any regular foaming soap.

Notes

You will need a foaming soap dispenser for this soap. Either buy one online or reuse the bottle from a store-bought foaming soap.

    So I’ve read through all the comments and there still doesn’t seem to be a clear answer on how to keep the soap from separating. I’ve read liquid lecithin? Has that worked for anyone? If so, how much do you add to a castille/moisturizing oil/essential oil combo for, say, and 8oz dispenser? Thank you!

    Holy crap this is a complete life changer! I’m so so happy to be able to make my own foaming soap and get rid of more yucky chemicals from our lives!

    Thank you!

    I find the soap causes a lot of friction and it gets difficult to rub them together. anything I can add to make it more slippery?

    I’ve been researching good for you and environmentally friendly hand soap. All the good ones are at least $10 a bottle! As a SAHM living off one income that’s just not an option. I just ordered the ingredients I don’t already have and am excited to make this!

    Is there a way to make the soap mixture thicker? Should I reduce the amount of water and add in more castile soap?

    Have you ever tried to foam an olive oil castile soap? I’m allergic to coconut and was checking out Penn’s Hill soap. Thanks!

    I made this soap last night. Is there a way to keep the olive oil from sitting on the top? Do you have to swirl the bottle before each use? Thank you!

    Mine didn’t foam at all. Not enough soap? I didn’t use olive oil since it was optional. Any suggestions?

    I got a little carried away and added a little aloe vera gel (very thin stuff) and witch hazel to the basic recipe. Some of the ingredients did not like each other and formed a scum-like white material which settles to the bottom. There’s not much of it, but there was enough to clog the foam pump. I have tried shaking the bottle to dissolve it, which does not work. I am thinking of zapping it in the nutri-bullet to break up the the thick stuff and incorporate it into the liquid mixture. If you have any ideas, I would welcome them.

    How wasteful (and harmful to the environment) to recommend pouring out a bottle of unused hand soap if not natural!

    I used a combination of bergamot, lime, basil & lemon EO for a citrus odor eliminator foaming soap
    Thank you for the basic recipe

    Thank you for this recipe! I just made it in two of my regular mouth mason jars with foaming soap dispensers I got on Amazon. So happy to be down with the mess of bars of soap! I think my kids will also be washing their hands a little better instead of just tapping the soap bar…haha

    I’ve never added olive oil to mine, but I’ve been doing this for years. It’s so much cheaper and I know exactly what is in it. Thanks for sharing. My son was just reading over my shoulder and wants me to add peppermint oil so it will smell like Christmas. I think he’s rushing this a bit. 🙂

    I don’t have a foaming pump, so just used a regular soap dispenser. It comes out watery (of course) but I just rub my hands together and it foams up nicely. Love it! Thank you for posting this!

    My question regarding this about a year ago was never awnsered. So I will anwser you! I have been using distilled water from jugs from the store and have not seen any issues. I use a store bought soap for my upstairs since we never use that one much (i was always scared it would develop bacteria sitting for months) but use this recipe to make my own for the kitchen and downstairs bathroom. I go through both pumps about every 2 weeks and I clean them and all pieces out using hot water and let dry completely before use again (I have 4 bottles for this reason, i use 2 at a time and let air dry the others until needed) so far I have not seen any mold or ickyness developing in the time it takes us to use the whole foaming soap bottle. Hope this helps!

    I make my own castile soap, when I make foaming hand wash with it, my hands feel sticky afterward, it goes away but still bothers me. Is there any way to stop this
