How to make your own Liquid Soap from Bar Soap!

I remember the first time I stocked up on bars of soap! I went nuts and bought at least 10 packages! Then, when I got home and was bragging to my husband about my score, he gently reminded me, “But we don’t use bars of soap.” At the time we were strictly liquid soap users.  Well, to prove my husband wrong I found another way to use up my soap!  Thanks to SavvyHouseKeeping for this recipe:

Homemade Liquid Soap

Ingredients you will need:

  • 1 cup Grated Bar Soap Flakes
  • 10 cups Water
  • 1 Tbsp Glycerin*

Other Items you will need for this project:

  • Cheese Grater
  • Large Pot
  • Spatula
  • Left over Soap Container with pump
  • Container for Extras
  • Funnel

Directions: Grate the Soap; you will need about 1 bar to get 1 cup of flakes. In a large pot, combine 1 cup soap flakes, 10 cups water, and 1 tablespoon glycerin. Turn on medium-low heat and stir until the soap dissolves. This should only take about 2 minutes.  Take off heat and let it cool completely. Once it’s cool, use the funnel to put the liquid soap into your container.  Now, enjoy your super frugal soap!

*Glycerin can be purchased at craft stores (Michaels, etc) or at many drugstores and supercenters.  Ask at the pharmacy.

If you are out of soap, this could be a fun, cheap way to build your stockpile! Here is a valid Walmart Scenario:

Lever 2000, 4-pack $2.23, Rollback Price
Use $1.00/1 – Lever 2000 Bar Soap – (bricks.coupons.com)
Final Price: $1.23 (or $0.31 a bar)

  1. Tea Tree Oil is a natural antiviral, antibacterial, & antifungal. If anyone has sensitive skin it should be tested on a small area before using. It should not be used by pregnant or nursing women.

    I just wanted to say thank you to all of you for your ideas and comments on how to save save save!!! My husband recently was layed off from his job and I am learning to coupon! Please keep the ideas flowing!!! Thanks again for all that you share, it is greatly appreciated!!!

    If you do go to Michaels to get the Glycerin bar/brick, try looking for the 40% off on regular priced item coupon that comes in the Michael’s sales ad in the Sunday paper. So long as it isn’t already on sale, you could get the glycerin at a pretty good price. Sometimes the stores have these ads instore and you can swipe a coupon from the ad, just ask the associate if they happen to have the sale ad. If you needed more than one brick of glycerin(probably for a huge batch since you only need 1 Tbsp which is either half or a full square from the brick), just get two coupons and do two transactions thekrazycouponlady way!

  5. I experimented with this when I saw the recipe come up on one of the blogs a few months back. I’ve now made two batches, and when my husband *finally* mentioned he didn’t like it, I admitted that I didn’t either. Maybe I’m not doing it right, but I even bought higher quality soap and the glycerin… oh well. Can’t win them all right? Just bought target brand liquid soap and have never been happier :)

  6. I love this idea! cant wait to try it, gonna have to make a run to Michaels first :)

    Sorry, I thought you were replying to the laundry detergent remark! Lol. What I said wouldn’t work for a soap pump.

    Bar soap makes great sachets. They are very inexpensive and your closets and drawers smell wonderful.

    Thank you so much for this. I don’t use bar soap but this is a great idea as I wash my hands a million times a day!

    This will work great for my Lysol Battery powered soap dispenser I got from RiteAid for .49¢.

    • how do you refill it?? I tried unsuccessfully!

        My husband got the top off of ours with a butter knife. After a little bit of work it popped right off. We have since refilled it about 5 times and everytime it gets easier to open.

        My husband used a butter knife to pop the top off of the Lysol soap bottle. We have three of these dispensers and have refilled all of them more than once. Each time we refill them they get easier to open.

    Anyone know how much the glycerin is? Even if you can get the bar soap for free, if the glycerin is too pricey it still may not be worth it. Cute idea though!

    • Amy Gallagher says:

      I get mine in the pharmacy section of walmart. Its with the first aid suff and its like $2.88 if I remember correctly. A little bit goes a looong way so its very cost effective for making hand soap. I keep it around anyway for making lip gloss and stuff.

    I should try this considering, only one person in my house uses bar soap and I got tons of Dove last week when it was a moneymaker! Anyone know the price of glycerin?

    • Anonymous says:

      LOL! I was looking all over the internet for this, trying to figure out what kind of glycerin to use. Then I decided to click the link she posted above for Savvy Housekeeping, and VOILA!! The post on that website says $2 per bottle.

    when our bars of soap are too small to use, i put them away into a plastic baggie. i have a recipe to melt them down and make them into new bars of soap, but i might try this recipe instead. thanks! (then i don’t have to waste my “good” soaps)

  14. I should definitely try this. I will, and share my experience. =)

      Sometimes men and children don’t understand the concept of rinsing the bar when they’re done using it so it ends up looking filthy dirty, and becomes the LAST THING you’d want to use to wash your hands. In the shower, I wouldn’t imagine it would make much difference. However – If you can get liquid soap for cheap or free, it’s worth it to just get what you use… And if the bar soap is a money-maker, I like the idea of donating it to someone who can use it. Rather than spending your profits to make it work, spend the MM profit on the liquid soap you prefer! =)

    neat. i have a ton of olay bars that i got cheap and bought for the free shaving cream and only one person in the family uses bar soap, but we go through hand soap like water so this will be fun to try out!

  19. Heidi Wood says:

    Ive tried this recipe before and its too watery….

    • Lisa Witt says:

      You should try powder instead. I do 3 bars of soap, 3 cups of washing soda, and 3 C. borax. (there are lots of variations out there, I think your water effects how well each variation works) I put the grated soap and other two in the food processor and make a nice powder and keep it in a 3 gal. bucket. It takes 1-2 T. per load. My cost per load right now is .02 because the soap was really cheap, it was Dial.

  21. We always do the trick with Dawn foaming soap, just buy one bottle of foaming dish soap, and then we mix about 1/4 dawn with 3/4 warm water, and make foam for the next several weeks. . . it makes our dish soap last SOOO much longer! My husband loves this, every time, he says “I love making the soap, its like sticking it to Dawn!” LOL!

  22. I have TONS of ivory bar soap, so I am going to experiment with this! :-)

  23. Im so excited to try this!

    • Charonne Alaiasa says:

      Ooohhh, I would love to learn how to make my own laundry detergent! Can you share one with us?

      • This is the recipe that I use:
        4 Cups – hot tap water
        1 Fels-Naptha soap bar ( I use Ivory)
        1 Cup – Arm & Hammer Super Washing Soda*
        ½ Cup Borax

        - Grate bar of soap and add to saucepan with water. Stir continually over medium-low heat until soap dissolves and is melted.
        -Fill a 5 gallon bucket half full of hot tap water. Add melted soap, washing soda and Borax. Stir well until all powder is dissolved. Fill bucket to top with more hot water. Stir, cover and let sit overnight to thicken.
        -Stir and fill a used, clean, laundry soap dispenser half full with soap and then fill rest of way with water. Shake before each use. (will gel)
        -Optional: You can add 10-15 drops of essential oil per 2 gallons. Add once soap has cooled. Ideas: lavender, rosemary, tea tree oil.
        -Yield: Liquid soap recipe makes 10 gallons.

        -Top Load Machine- 5/8 Cup per load (Approx. 180 loads)
        -Front Load Machines- ¼ Cup per load (Approx. 640 loads)

          I have always wanted to try this. Do you find that it gets the clothes as clean as regular laundry detergent? What about stains?

          • Lisa Witt says:

            I’ve been making my own for several months, but I just process mine and keep the powder in a small bucket. Takes up less space and is less work. We have an HE machine and this actually works really well with it, our clothes are nice and clean and smell “clean” not like perfume. Though, like the poster said, you could add scents. In the case of the powder, you could use scented soap. And I haven’t noticed any fading or anything. Brighteners in regular detergents are bad for your clothes anyway and my husbands military regs say he can’t use them. As for stains, it seems to work just as well as the All did that I used for years. If I catch it right away, they come out, If I don’t, then they don’t.

            It’s just to note that it has to be The Super Washing Soda!! Just the regular stuff won’t work because it does not have the sodium carbonate. Hope this helps! I make my own as well using this but I use the Fels- Naptha bar and it works great on our clothes.

            You can find it in the laundry detergent aisle with boxed detergents. Washing soda has a higher ph than baking soda, it’s stronger. If you ever clean with it, you should wear rubber gloves.

    Great now how do I turn liquid soap into bars of soap. I was so proud to buy him mens bodywash, but he will ONLY use bars of soap…sigh.

  26. If you take Ivory bars and put them in the microwave (just watch it, it’s cool to watch, but you don’t want to burn it) they expand and you can just crumble them in your hand to make the flakes. Makes your whole house smell like ivory. Kids like the flakes when they wash in the bath too :)

    • Is it REALLY that much of a savings? it sounds like entirely too much work to save so little.

      • Sorry, Rhonda…that wasn’t meant as a reply to you. Just a reply to the whole thread.

        • It’s ok! I was thinking that it did seem like allot of work for liquid soap, which is fairly cheap, but I’m guessing that if you are trying to find something to do with your soap bars, it would be a good idea. But I’m thinking that the glycern isn’t cheap.

          • Glycerin is like 3 dollars in my rite aid. The whole thing for me makes about 32 ounces of liquid soap. My family used to buy dr bronners liquid castille soap which was 15 dollars a bottle and lasts about 3 months because we put that in a foam pump. Buying the Dr Bronners bar instead costed 5 dollars and makes the same amount of liquid soap. 5 dollars for a soap that will last us 3 months and sometimes longer is great savings. Especially since my parents will not get off the Dr Bronners kick. As far as the work is concerned. Melt soap, add glycerin pour in bottle. It shouldnt take more than 5 minutes. You can boil water in your microwave to melt it in.

      • Alaine, I think this was meant to be a “what if” scenario. I agree it is ENTIRELY too much work to make my own liquid soap, but it is a really good idea if, like the writer, you overstock on bar soap. On occasion I’ve had to make my own dishwashing soap because I’ve run out and couldn’t get to the store. I never run out of hand soap because I stock up when Bath and Body Works does their 7 for 20 sale. I get enough to last me for the year then stock up again.

          Hi everyone! I LOVE B&BW. You should try to go to a Outlet. Their soaps are as low as $1. The closest one to me is Gaffney, SC (2 hours away from me). I always go on the way to GA (to visit family). It is totally worth it! Yay B&BW!!!

  27. Kalen Crane says:

    I wonder if there is an easier way to grate the soap, maybe run it through the food processor for a few seconds? Any ideas?

    • You can use the food processor. That’s how I grate my soap when I make laundry detergent.

      • Anonymous says:

        When I make this recipe, I find it SO much easier to chop the soap with a Chef’s knife or a large serrated knife that I only use with soap and I have a flexible cutting matt under it for any shavings. Then I make the cutting matt into a “U” shape and dump it into the pan on the stove. Makes clean up a snap! Depending on the type of soap (glycerine versus opaque bar soap like Ivory), sometimes chopping it makes more shavings (than grating would make shreds), and the pieces are small….It doesn’t matter that the soap is chopped since you’re melting it, and it sure beats having to clean the grater.

  28. Jen Boys says:

    Another really great money saving tip is to reuse the foam hand soap dispensers, fill about a quarter of the bottle with liquid hand soap, and then fill the rest with water. It foams and you use soooo much less soap!

  29. Another Scenario is check your local Kroger!

    We get Ivory coupons all the time that usually double since they range from $0.35 or $0.50 off each 3pk. When Kroger runs Ivory bars on sale 10 for $10 then you can get them free with a $0.50 coupon or pretty close with the $0.35 coupon!

    Ohhhhh..I have some Dove beauty bar, can they turn into body wash?

  31. Joan Smith says:

    great idea! We don’t use bar soap any more but still have a few bar left. I will totally try this so they won’t go into waste! Thank you.
