Easy Peasy Liquid Soap

homemade liquid soap

We have bars of soap in all our bathrooms but I like to keep liquid soap by the kitchen sink for when my hands are manky with dough or minced meat. It’s super easy and cheap to make

  • 1 tsp of finely grated soap
  • 200ml of boiled water
  1. Mix the grated soap with the boiled water
  2. If the grated soap doesn’t dissolve fully, heat mixture on high at 30 second intervals until it’s all dissolved.
  3. Stir and check that all the soap has been dissolved
  4. Leave to cool
  5. When cool poor into a soap dispenser.

If the soap is too thick when it’s cools add 30ml of water and heat for 2 minutes, stir and leave to cool. Repeat until soap is desired consistency.

You will be surprised just how potent the soap is, don’t be tempted to add in too much grated soap because if you do you’ll end up making tons of liquid soap!

You can try this recipe with any soap but if you’re buying some specifically then, if your budget allows, aim to buy palm oil-free soap, preferably unwrapped or if that’s not possible in paper packaging.

If this doesn’t work for you or you don’t want the hassle you can get refills of bodywash or liquid soap in quite a few zero waste / health food stores around Ireland. Just check my Map of Eco Stores

Alternatively Swedish company Forgo will aricle you powder soap that you just mix with water in a dispenser of your choosing.

    1. It has been for me. The main issue is knowing how much water to add and making too much in one go. I’ve learned that it’s better to use a small amount of grated soap to begin with and to add small amounts of water each time, measuring as I go, until i get the right consistency. Once I’ve done that the first time I know the proportions for that soap from then on. If you do make too much just store it in a jar until you need to top up your soap dispenser. Also if you can get one of those foaming soap dispensers you can have foamy soap!
