Turn a Bar of Soap into Liquid Soap

How to make Liquid Soap

I have a thing about soaps.  Either I like expensive bar soap, or else, I like liquid soap.  Plain old Dial or Irish Spring soaps just don’t cut it for me. For showers, I enjoy my expensive bar soaps but for normal hand washing,  I prefer using liquid soap because it is tidier on my bathroom sink counter.  This great tutorial shows how to turn any ordinary bar soap into Liquid soap.Make your own liquid soap from an ordinary bar of soap.

Many homemade products do just as good a job as those the retail products that you buy in stores.  Things like disinfectant wipes and liquid soap can be made at home for a fraction of the price of store goods.

Making liquid soap is so easy. All it takes is melting the soap with water, adding a little vegetable glycerin, and in no time at all, you have liquid hand soap. 

To make liquid soap, you will first need a bar of normal soap. Then get out a food grater and grate away. You’ll need to end up with about 1 cup of soap flakes from your bar.

Next, combine the soap flakes in a large pot with 10 cups of water.   Add 1 tbsp of vegetable glycerin to the water. Bring to a boil, then reduce the heat and cook it over a medium low heat for 1-2 minutes until the soap dissolves.

You can also add 1 tsp of essential oils at this time if you would like your soap to have a lovely scent. Lavender, Tea Tree, Eucalyptus, Lemongrass, Orange, and Peppermint all make great scented soaps. (affiliate link.)

Let the soap cool completely, then use a funnel to pour it into a fancy soap dispenser.  If the soap is too thick, use a hand blender to beat it until smooth.  (add a tiny bit of extra water to get the consistency that you like.)

Easy peasy and so much less expensive than normal liquid soap!

I tried this but mine ended up watery and wasn’t thick enough to get a lather up. It wasn’t completely cool when I saw it very runny so wondered if it cools thicker or if I’ve got the ratios wrong? I don’t have a cup measurement (UK) so did a conversion which said this was 2.36ml so is this where I went wrong?

is there a substitute for the vegetable glycerin?

If you Google this question, you'll get some ideas but I have not tried any of the substitutes so I can't attest to how they will turn out.

Thanks for sharing the technique. If I'll turned a bar soap into a creamy soft bar, what should I change in your given recipe?

I can't suggest changes, since I have not tried to do what you suggest.

Mine turned out slimy, anything I did wrong? Should I wait longer about 12 hours so far

I'm not sure why it would come out that way Marisa. It could be simply the contents of the soap you used. It worked fine when I tried it.

Can this be used in a foam soap dispenser?

I don't think it will foam Rachel.
