Turning Bar Soap into Liquid Soap

I was able to buy a lot of bar soap for 10 cents a bar and I was wondering if I could turn that into liquid soap? Appreciate any ideas.

YUP! Just cut the bar soap up into chunks, put in a saucepan with enough water to cover, and heat slowly, stirring occassionally (slowly). When it’s melted, let it cool, and check the consistancy. The first time you do this, you may need to re-heat it and add a bit more water, until you get the proportions straightened out. Once it’s cool (and it’s been thinned enough), just pour it into a clean pump dispenser, and it’s good to use! You can also add a drop or two of essential oil at this point to make it smell nice.

Another way (but it takes a while) is to get a large jar (like a clean pickle jar), put about an inch to an inch and a half of water in it, and add bits of soap. Close the jar and let it sit for a month or so. This is good to do with left-over bits of bar soap, so you don’t waste it!

A fun craft is to simply melt the soap (without any water), add a few drops of a fun essential oil and then pour it into a mold! You can also pick up colouring that’s OK to use for soap at your local craft store, too. That way, you can make pumpkin soaps that smell like pumpkin pie, or candy-cane scented soaps! I’ve even heard of taking fabric leaves and dipping them into the scented soap to make one-use soaps for company! The leaves would then be re-usable, once they were washed.

Hope this helps! :)

I just take the soap and shave into small pieces and then throw it all in my food processor with a little water and pulse till it is all liquid and then I pour it into my soap dispenser. I keep all my little ends of the shower soap till I have enough to make a batch. No cooking needed.

Here’s a recipe that was passed on to me from another group:


3 cups of water
One bar of your favorite soap
Grate one bar of soap into a microwave safe bowl. Add three cups of water. Heat in microwave on high for 2 mins. Take out and stir… then heat 2 more mins. then stir… 2 more mins. then stir… for a total of six minutes. Allow it to cool and place in your favorite pump container.

I tried making it, but got impatient with how thin it was, forgetting it would thicken as it cooled, and kept adding more soap to it. Once it did actually cool, it was almost completely solid again and I had to sit there and mix in extra water. I ended up with about double the amount of soap I intended and if its sits and doesn’t get used for awhile, it starts to gel and you have to shake it up. I’ve been told by friends that have been soaping for years that the only “real” way to make a liquid soap is through “hot process” soap making which is difficult. Most people who say they make soap actually make either melt and pour soap or “cold process” soap.

    I wonder if you used half the recipe at a time if would b better. You would use it faster and mayb it would not thicken as much? Just a thought.

Im doing the microwave version right now but mix is very thin, should i just put it in pump and see if it thickens when it cools?

Can you turn a liquid soap into a bar soap?

I have read somewhere that you can add vinegar and 1 tsp borax to reg handsoap that it extends the life of the soap. when you are about 1/2 way through your soap contanier you add borax and fill with vinegar. I have done this and it makes the soap runnier. I wonder if you added it to the thickened soap if it will make it a good consistency? I guess I will have to experiement!
