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.

Author: Katie Wells

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.

Do you make your own soap already? If not… will you start now? Share below!

    I’m so excited you posted this. I was thinking about making my own foaming soap and hadn’t gotten around to finding a recipe. If I wanted to use it as body soap, would you recommend adjusting the ingredients at all?

      I use liquid castile soap and coconut milk (equal parts) for a body wash, I love it. I use Dr. Bronners mild….that with the coconut milk gives it a very light fresh scent that isn’t drying.

        Do you become immune to the tea tree oil? I have been using dr. bronner’s hemp/tea tree liquid soap in a pump dispenser for a long time, it does dry my hands out a lot, so I am trying to figure out a better hand soap option. Why would I want a foam soap rather than a liquid soap? I need to find an easy hand soap for frequent use that is moisturizing. I like the tea tree for it’s antibacterial property, but maybe using it all the time is not a good idea? Thanks for any help.

        Doesn’t the coconut oil harden and clog up your dispenser (unless it stays warm)?

          it shouldn’t, but it depends on the temp in your home. You could try some Vit E oil instead! Good for the skin and won’t harden.

          You could use fractionated coconut oil if you are worried about it hardening. Fractionated CO is liquid at all temps.

    I love this soap recipe but keep having a problem with the dispenser. The pump is not recoiling (you have to pull it back up). I have bought two different foaming soap dispensers and it happened with both within a few days of making this soap. I have 2 little ones and it’s difficult for them to pull the pump back up every time. Any suggestions?

          Could be the lid is tightened too much. Like with baby bottles & water bottles, sometimes if the lid is too tight it won’t let enough air in and even out pressure for suctioning contents out. Downside is if you have to loosen too much it could leak if turned on the side.

      I have the exact same problem with the pump getting stuck. I made liquid soap from a natural bar soap, which is quite goopy/jelly, but works alright in a regular soap dispenser, but in the foaming dispenser, the pump gets stuck… I ended up dumping it out of the foaming pump and now I might have to go back and try again but add some oil??

        You need to add water. The kind of soap that works in a traditional hand soap dispenser needs to be watered down by at least half to work in a foaming one.

      Not all the people responds equally to olive oil soap.

      I have found that for some people high percentage olive soaps can clean too deeply the skin drying it out.

      I prevent that using 30% olive oil, 25% sunflower, 5% castor and 40% palm, yes, palm… I am from Costa Rica and we have very good laws protecting the workers and environment and the lands have decades with the same palm trees that were planted for rebuilding the economy of agricultural little towns that collapsed after the big banana companies left the country and thousands of unemployed people, in other words no orangutans in danger (we don’ t have them anyway) The castor has to be added after trace and it will be very moisturizing.

      My girls have trouble with the peppermint & citrus soaps making their hands exceptionally dry. I use almond, rose, or lavender Dr. Bronner’s and they haven’t had any more problems. I don’t add the oil either, just the soap & water and it works just fine (used the same dispensers for over a year).

        Lemon, (& most citruses) is a degreaser so it will strip all of the oil from your hands. That’s why it is used regularly in laundry and dish soap. Also, citrus oils are predominately made of monoterpenes which are prone to oxidation and become skin irritants when that happens. Peppermint has menthone, a ketone, which is a skin irritant in large amounts, or if a lower grade is used. Adding some skin nourshing essential oils comprised of alchols, esters, and other ketones will help to avoid these issues….think Lavender, Rosewood, Myrrh, etc., like you you. Adding a skin soothing carrier oil will help prevent these problems as well.

      Hi. I have heard that Jojaba Oil is GREAT for eliminating dry skin (hands). I get dry hands so so bad in the winter esp if I have em in water too often. So I’m currently making my first NON TOXIC foam soap! Although I have coconut oil, I realized I need Jojaba oil too to take care of my dry hands:-)

      I’m a single dad raising my 10 year old son. We bought SoftSoap Antibacterial from costco. used it for years. Every winter my son’s hands cracked, chapped bright red and painful. His doctor recommended petrolium jelly. We used it and it worked. THEN I READ THE INGREDIENTS on the SoftSoap huge jug from costco. BAD BAD BAD! We started using Doctor Bronners bar soap in the shower and Doctor Bronners liquid Castille soap from Trader Joes in a diluted form for liquid soap. Guess what? NO chapping, cracking redness or pain and NO PETROLEUM JELLY. READ YOUR INGREDIENTS ON ALL YOUR FOOD AND BEAUTY PRODUCTS! DO RESEARCH! MOST OF IT IS TOXIC POISON!!

      i know this post is old but wanted to let you know that using antibacterial soap for a long period of time, 3 months or more makes you become immune to it…so it isnt doing any good anyway, all you are doiongis adding chemicals you dont need. Its like taking antibiotics for too long, they stop working and cause harm.

        We recently discovered that if there’s turmeric on our dish sponge, putting bronner’s Sal Suds on the sponge turns that area pink. Sal Suds is their dish soap. As a backpacker I learned that if you use iodine treated water to wash a pot you cooked pasta in, the pasta’s starch would react with the iodine’ turning the water blue.

      All soap has lye solid soap has sodium hydroxide, liquid soap has potassium hydroxide. Without lye as a catalyst for saponification you cannot make soap. There is no lye present after the saponification process but it is absolutely necessary to turn oils into soap. You won’t find a soap without it.

        Oh right, well I’m not against Lye at all, but I just don’t think I could go through the whole process of making it (for different reasons)… I was more like wondering what I could use as a substitute for soap. I know people who wash only with honey, others who use sugar scrubs etc…

    I’ve been making foaming soap for a couple years. I mix Bronners castille soap with water 1:5 ratio. Trader Joe’s has the best price around for the soap. I used the foaming dispensers from Target (Method) once they are empty. I found buying a dispenser by itself was not worth it.

            Sorry I am a couple of years late getting to this. You don’t need a foamer. If you use 50% Castile soap then grind some sea salt into it and mix well it turns into something I can only describe as a ‘glob’. The other 50% can be made up of all water, all oil or a combination of the 2 with honey and/or Aloe and/or glycerin etc (a light oil like rapeseed is good, try a combination with coconut oil and honey). Using all oil will make your soap last longer than using water as long as you sterilise your implements, it doesn’t seem to make it greasy in my experience. Add your essential oils to the oil or water you’re adding and account for it in the 50% as this can affect the viscosity. I have found that any more than 50% it turns to liquid. You then add this very gradually into the ‘glob’ until all the oil is combined or if you like your soap a bit thicker don’t add quite 50%. It goes silky smooth like commercial soap and you can use it in an ordinary soap dispenser. I use 60 drops of oil to 300ml , I suppose that’s about 6 per fluid Oz in imperial. Depends how strong your oil is, how big your dropper is and how strong you like it. Hope that helps.
