DIY: Eco Liquid Soap

So, it turns out that many cleaning fluids, such as anti-bacterial liquid soap, contain something called methylisothiazolinone, a chemical found to be allergenic, cytotoxic and linked to nerve cell death, as well as Triclosan, another anti-bacterial chemical registered with the Environmental Protection Agency as a pesticide and is believed to destroy fragile aquatic ecosystems. The obvious alternative to using these chemical-filled detergents is simply to use all-natural bar soap. But, waaa, you don't like bar soap because it slips into the sink, looks messy and "dirty" sitting in its dish, and then it gets so tiny that you can't use it anymore. What to do? You can make natural liquid soap from a bar! To learn how,



  • 4 oz. bar of natural soap
  • Grater
  • 1 gallon of distilled water
  • 1 big pot
  • Hand mixer

Here are the steps, summarized from Suite 101:

  1. Grate your bar of soap.
  2. Heat the water just enough to steam.
  3. Add the grated soap to the water.
  4. Take the mixture off of the heat, and let it sit for 15 minutes.
  5. Blend the mixture, with a hand mixer if you have one.
  6. Let it sit overnight.
  7. Make sure the mixture is completely blended. If not, blend again, and let it sit. Then, blend again.
  8. Pour it into an olive oil bottle and wash your hands!

I make soaps, including a pure castile (olive oil) bar. I simply grate bits of castile soap & add them to a big pot of water. I don't heat it or do anything, just let it sit for a few days. Voila!...liquid castile soap!

I am findind that making soap is a business in it's self. I already make scrub and hand made Himalayan Salt Lamps. I am looking for a soap maker that can make what I need. I need Goat Milk Soap, and Olive oil Soap, that has my main product in it. That would be Dead Sea Salt, and Himalayan Salt. I already have the fragrances, and salt, I just need a soap maker that can make it for me. Please contact me at If you need business, contact me! Check out my web site at Staci Staci

I see someone recommends coconut oil, but how much?

I need HELP! I have 100 bars of soap that I need to turn into liquid soap! I bought melt and pour Olive Oil Soap and Goat Milk Soap to add to my product line. I sell Himalayan Bath Salts and Dead Sea Salts. I thought it would be really great idea to add Dead Sea Salt to the soap bars. I quickly discovered that it messes with the fat in the soap, and will not get hard. I then added Himalayan Salt. It set, but because the salt has so many minerals, it scratches your skin. I am now stuck with close to 100 bars of soap that I need to turn into liquid soap. I have no idea how to do that? HELP ANYONE!

I love this idea. I'm trying to reduce the plastic I use, so making my own liquid soap and putting it into a beautful container is just the thing. Thanks! A gallon should last a long time so any effort will be worth it.

Its a nice idea, but its something I don't have time for.

FYI this is also a way to "save and use" those micro-slivers of soap bars that can be so annoying. Just save them up, and when you feel you have enough, melt them together to make hand soap from the leftovers.

Oh, Just Oh, I have no idea. I wonder how much will be lost to evaporation, as it says heat water to steam. I don't know, but as I said before, I'm sho gon' try this tho.

What a great idea. I'm definitely going to make a batch, but maybe not an entire gallon's worth. terryt18, if I cut the distilled water back to 1/2 gallon how much do you think I'll end up with?

casasugar- where do you get that top for the olive oil bottle? and like terryt18 said how much does this recipe make? I really like bath and body works soaps but they all have Triclosan :( We use Method hand wash in our kitchen but our bathroom has the anti bacterial soap :\ eek.

What about - Hey! Awesome idea! I just found, at Big Lots, a ton of Every Man Jack soap for 50 cents a bar. I stocked up because as you know the soap is tallow, paraben, and sulfate free. Perhaps I'll make some handsoap from a bar of this. But how much liquid soap does this recipe make?
