You'll enjoy making this silk soap recipe with it's luxuriously creamy, palm-free lather.
Coconut oil, Shea Butter, Olive oil and castor oil make up the base ingredients of this natural soap along with Kaolin Clay for added slip and of course silk peptide to give the lather it's wonderful texture.
I've used mica's and oxides to colour the handmade soap and normally this would give the soap a matt like finish.
The addition of silk, however, gives the soap a slightly glossier appearance.
You will also notice when holding a soap with silk in one hand and one without in the other, that you can really feel the difference.
The silk soap recipe has a much smoother feeling finish.

Begin by preparing your colourants. Divide the 4 tablespoons of olive oil into four containers. To each container, add 1/2 teaspoon of Kaolin Clay and 1/2 teaspoon of each colourant.
Be sure to mix the colours really well. Use the back of a spoon to break up clumps and blend until you have a smooth paste. Put aside.
Next, weigh out all of your ingredients. Place the hard oils into your soaping bowl/pot and add the lye to the water.
Mix the silk peptide powder into the hot lye water until it is completely dissolved. This can take a few minutes.
Don't worry that the water goes a golden colour. This is normal and doesn't seem to change the colour of the soap base.
As soon as the silk has dissolved, you can add the lye water to the hard oils. Stir gently until all of the hard oils have melted.
Add the soft oils to the soap base and mix with your stick blender and/or whisk until a light trace is reached.
If you are adding scent, now is the time to do it. Once again, a slower moving fragrance or essential oil would be best since you will be working with the soap for awhile.
Divide the soap between the containers of colour you prepared earlier and mix until incorporated. Pour the coloured soap into squeeze bottles. Alternatively, pour directly from the cups. Just be sure to pour nice thin streams of soap into the soap mould. This can get hard to do as the soap thickens up in the cups.
Squeeze (or pour) the coloured soap into the soap mould until all of the soap has been used up. Be sure to alternate between colours frequently. Marble the soap however you like. I used my spatula and did a (messy) figure eight pattern. Regardless, this silk soap recipe turned out quite pretty.
