Make Your Own Liquid Hand Soap From Scratch

You can learn how to make you own liquid hand soap in just a few easy steps. It’s an easy thing to make and has a lot of advantages.  For starters, it’s very frugal!

I make my own soap (For recipes, go here.), so there is very little cost to using two to three bars to make liquid soap. It actually ends up being tons cheaper than buying it from the store, and it puts you in charge of the ingredients.

It’s also super easy to make on your own.

In order to add scent, you can add essential oils to the batch, or add a few drops after pouring the soap into your dispenser so that you can change the scent each time. You can also add antibacterial essential oils to give your soap an extra punch.

Find a list of antibacterial essential oils here.

It’s also a wonderful thing to have with little kids. 

It’s a luxury that I like, because it seems to be cleaner than the dirty soap bars that I find sitting in the sink (if you have little kids you’ll know what I mean).

DIY Liquid Hand Soap

This soap recipe is very simple. And you only need two ingredients! There’s a little freeze and thaw method I use to make it the perfect creamy thickness. If you’ve tried to make your own liquid soap before and it ended up being too thin or thick, then try this method.

This recipe makes one gallon. You can divide it in half if needed.

Makes: 1 gallon
Author: Kelly

Equipment

  • 1 large stainless steel pot
  • 1 stick blender
  • 1 cheese grater
  • 1 large glass bowl

Ingredients

  • 1 gallon water
  • 3 bars soap

Instructions

  • Put one gallon of water in a large stainless steel pot and turn on to medium heat.
  • Grate 3 bars of natural soap into the water. Stir until melted and remove the pot from the heat.
  • Allow soap to cool and then pour it into a large glass bowl or other container with a lid. Place in the freezer. Leave it in the freezer until it starts to freeze. If you leave it too long and it freezes solid, just leave it out until it thaws.
  • Blend with a stick blender. Cover and let it sit at room temperature for 24 hours. Blend one more time and then store in a sealed container until ready to use. Use within 8 weeks for freshness.

Notes

You can leave it at room temperature after removing it from the stove, but I’ve found that the freeze and thaw method makes sure that it reaches a wonderful creamy thickness and texture. Very watery soap will become thick after freezing and thawing. 
The 24 hour wait is so that you can break up the molecules one more time before storing. Often they will reform in that first 24 hours where it’s too thick (forming long chain bonds like snot). Blend again when (or if) that happens. It breaks up again to a beautiful consistency. 

Tips to Making Great Liquid Hand Soap

The first thing I learned when trying to make liquid hand soap is to not use Castile (olive oil) soap bars.  The reason for this is that Castile soap is extremely soft and will make a very watery hand soap.  That is fine, but most people like to have a hand soap that’s a bit thicker. .

Second, you can use less soap bars. It will be thinner, but will still be effective.  I like to use three bars for a creamy hand soap.

Third, liquid hand soap typically bonds back together over time. You may start with a watery thickness, then it will turn into the perfect thickness, only to finally end up in a thick blob. This process will happen faster with temperature differences. The nest thing to do is to cause it. Follow the directions in the recipe to cause the binding to occur so that you can break the bonds again. The soap molecules may bond together again over time and you’ll need to use a stick blender to mix it again, but it will stay at a good consistency for 4-6 weeks at least.

Fourth, homemade liquid hand soap does go bad. When making beauty or bath products, any product that has water added to it tends to last less than pure oil products. If you smell a dusty scent to it, this is it starting to go bad. Make as much as you will use in two months for the freshest hand soap. I’ve had soap last longer than that (3-4 months), but you can use the two months rule as a plan for how much to make.

Want to make a larger bath or want it to last longer? Put what you are not using in the freezer. It will last indefinitely when frozen. Save

    I made a batch of your crockpot soap (wonderful), and used those for this recipe… The consistency is rather watery, no matter how many times I go back and add more soap to it – it gets more concentrated. But doesn’t thicken. It lathered well from the beginning, just watery…any suggestions?

    I’ve read that adding glycerine can give the soap a slimy texture… I did add about 1.5 tbsp the first time, 1.25 when I went back and added more soap – this did not seem to make any difference whatsoever. The soap is absolutely perfect in every other way: it lathers great, is rich, feels nice and smells nice – just super watery (and very concentrated, now that I’ve added so much of the bars to it) . I’m not even sure now how to dilute it, and how much glycerin to add at a time. I really don’t want to ruin this batch…my husband is already completely unsupportive, and feels I’m wasting money (even though I’ve presented the money-saving, more healthy, less waste arguments and demonstrated the good bars…)
    Any suggestions on how I should go about diluting my liquid solution, and how much glycerin I should add? I could provide more specifics, if you’d like -just let me know.

    Thanks for your help!!

      Mishell,
      I’m not sure exactly why yours is staying so watery….It never does get as thick as store bought because it doesn’t have the same thickeners, but it should thicken more than what you are experiencing. What I would suggest is to heat it in a large pot, double the amount of water (so if you have one gallon, add one more). When warm and combined well, pour into two gallon jugs and seal.
      THEN, get a cheap soap dispenser that foams, dump the soap in it, or use it if your husband would rather you to 😉 and use it from now on with your homemade soap. It will foam and seem “thick” to those not used to thinner hand soap.
      I hope that is a workable solution.

    I understand it’s kind of a trial and error process when you’re first starting out in soapmaking 🙂

      Hi Elise,
      Any hard bar with natural ingredients. A good natural lye bar will do. It’s just that the castille bar doesn’t allow it to thicken for some reason.

      You can add water. The consistency will vary depending on what soap bar you use. I used a beer soap with juniper berry once and it was like elementary way the molecules connected to one another. But every other bar I’ve used has been thinner, but perfect. Heat it if you need to and add a little water to thin it out if needed.

      No, glycerin was mentioned in the discussion of possibly thickening the soap if it comes out thinner due to the fact that a more castille soap was used.

    I’ve been successful with this in thickening up my liquid soaps by blending in shea butter, salt & fine brown sugar. Per 1 c… start with 1/2tsp of brown sugar& salt…1 level tsp shea until it blends thick. Add more hydrolsol or castile if its too thick. LOVE YOUR SITE!!!

    I had some soap that didn’t harden as usual so I used your liquid soap recipe with the bars. It has been several weeks since I made it. It has been sitting in my cool basement. The soap is still very liquid. I think it will probably work with a foaming dispenser but wondered if there was anything I could do to thicken it. The bars of soap were made with goats milk, olive oil, coconut oil and palm oil.

    Thanks for all you share with us. I’m learning a lot.

      You said didn’t harden, “as usual”. I’m not sure what you are using so it’s hard to advise you. You can try adding a half bar or full bar of shredded soap, depending on the size batch that you’ve made.

        Hi Kelly,
        The batch of soap I made was with goats milk, pomace olive oil coconut oil and palm oil. I had to leave it several days longer than usual to unfold because it was too soft. It finally did harden but is still a softer bar than usual. I shredded these bars as your recipe suggest but that solution is still pretty runny. You say not to use a castile soap bar but I’m not sure what makes a castile soap. I’d like the liquid soap to be a bit thicker. Any tips?

          I’d freeze it, then thaw and use a stick blender or hand mixer on it. Sometimes it needs a little help bonding into a thicker consistency.

    Thank you for this recipe! I found a similar one that said to just let it sit for 24 hours. I did and it just separated. Waited a few more days, still nothing. I found your recipe and decided to try the freeze and blend part, and it totally worked! It’s thick and looks like it’ll work great! I’m still on the waiting 24 hours before use part, but I was too excited to share my excitement lol
