I often get asked about a special soap recipe, because most soap makers don’t realise that any soap will work! Soap dough is actually a normal soap recipe that has gone through the saponification process but hasn’t been allowed to dry out (cure). It’s not a special formulation and doesn’t contain any special ingredients. Really, any soap can be used, and I often use my left over soap from other projects, either cut offs or the leftover in my soap pot, and will it turn into little soap beads or other soap decorations for my cupcakes. The trick is, as mentioned before, to not let the soap dry out. As long as you store it in an airtight plastic bag or container, the soap dough will keep for at least a month or longer.

You don’t have to use a special soap dough recipe, any left over soap that is still soft enough can be used!

However, there are times when you do need a bit more soap dough for larger projects, or if you want to prepare a batch ahead, so I have added a special soap dough recipe at the end of this blog post, which will give you a nice white soap base, like the one in the picture below. You can make the soap as usual using the cold process method, letting it set in the mold overnight, before unmolding and storing it in a plastic bag. The soap should be soft and pliable. If it is too wet and sticky just let it dry out a little longer. You can either use the soap as it is, or add micas, soap colourants, or natural colourants to colour the dough.

The consistency of the soap should be like play dough – easy to knead and mold. If the soap is a little too sticky, you can mix in a little corn starch. Take as much soap as you need for the project, and leave the rest in the bag, as not to dry out. Knead your soap before using. The warmth of your hands and the friction will help soften the soap and make it easier to work with. I do recommend wearing gloves, especially if the soap is less than 2 weeks old, although I have to admit I’m don’t always wear gloves when playing with my soap dough.

If you are very creative, you can shape your dough into any little creature or object. It’s just like working with play dough. There are some very creative people out there, have a look on YouTube and search for polymer clay or fondant miniature tutorials. To paint the shapes, mix a little mica with alcohol and using a small paint brush, just paint on the mica (for example eyes, shading, etc).

Here are some simple tutorials to check out and get you started:

You can also use little silicon molds, such as berries or shells. Just press the soap into the mold and then carefully unmold. You can use the shapes straight away, but if you are planning on storing them, let them cure for a few weeks to harden before placing them into a container.

My favourite use for the soap dough is making little mica coloured soap pearls, which are so easy to make and great for embellishing your soap creations. Just roll your soaps into little balls with your hands, and place them in a little cup or container. Add a little mica, depending on how many beads you are making, about 1/4 teaspoon should be more than enough, and then swirl the beads around in the mica. When you take out the beads, give them a little shake to remove the excess mica, and store them in an open container to harden them and finish curing.

Here’s my favourite dough recipe, although as I mentioned before, you can just as easily use any left over soap from another project.

To make the dough base as white as the little shells in the picture above, I added titanium dioxide, which you can get from Pure Nature.

Soap dough recipe

  • Difficulty: intermediate
  • Print
Before starting, make sure you wear protective goggles and gloves and work in a well-ventilated area, free from any distractions!

Ingredients

  • 140 g olive oil
  • 100 g coconut oil
  • 100 g sunflower oil
  • 100 g cocoa butter
  • 10 g castor oil
  • 60 g caustic soda
  • 140 ml water
  • 1 teaspoon titanium dioxide

Directions

  1. Measure out the water into a heat proof Pyrex jug. Weigh out the caustic soda and carefully add it to the water, avoiding any splashes. Gently stir until all the caustic soda has dissolved and the lye water is clear.
  2. In a large heat proof Pyrex jug or pot, weigh out the coconut oil and cocoa butter. Heat in microwave (if Pyrex jug) or stove (if pot) until all the oil and butter has melted.
  3. Add the olive, sunflower and castor oils to the now-liquid coconut oil and cocoa butter, and give it a quick stir. Set aside.
  4. Prepare the titanium dioxide, by mixing 1 teaspoon of titanium dioxide with 2 teaspoons of water.
  5. Once the lye has cooled down to room temperature, and making sure you are still wearing protective goggles and gloves, carefully add the lye to the oils.
  6. Add the titanium dioxide mixture.
  7. Then, using a stick blender, pulse and stir until the oil/lye mixture has emulsified and thickened to medium trace.
  8. Pour the soap into the mold and leave to set overnight.
  9. The next day, unmold and check if the soap is not sticky anymore. If it is, let it cure for another day or so, just enough to dry it out a little more, but not enough to harden.
  10. Cut the soap up into cubes and knead them together, to make it soft and pliable. Make sure you are wearing gloves! The soap is still zingy!
  11. Store the soap dough in an airtight container or plastic bag until needed. It will keep for a month or longer.
