Tutorial: Pastel Four Color Gradient Layers Soap (ISC)

Jaime at Sleeping GypsyIt’s time for another Inspiration Soap Challenge tutorial!

Jaime from Sleeping Gypsy received one of the ISC kits, and whipped up this bright treat inspired by Mungo Jerry’s In The Summertime. Jaime challenged me:

make a soap has gradient layers using 4 colors. 🙂

Four color gradient layers? Sure thing! I’ve been wanting to do this with Lab Colors or another bleeding colorant, but I grabbed micas for this one.

Pastel Four Color Gradient Layers Soap Recipe

This formula is sized for the Brambleberry 10″ silicone mold, you can resize the formula for your own mold by using SoapCalc.

Soap Recipe Used

  • 8 ounces Rice Bran Oil
  • 5 ounces Apricot Kernel Oil
  • 5 ounces Avocado Oil
  • 2 ounces Castor Oil
  • 10 ounces Coconut Oil
  • 6 ounces Cocoa Butter
  • 9.90 ounces Distilled Water
  • 4.88 ounces of Sodium Hydroxide

I usually buy my oils from Soapers Choice.

Fragrance Oil Used

Colorants Used

PREP WORK: Weigh out your soaping oils. I like to add my fragrance to my main soap pot so I can’t possibly forget it later! Make up your lye solution, too!

Prep four mixing cups that are large enough for a quarter of the batch (around 4 cups), each one containing a different mica and a teaspoon of the oils from the main pot.

GET STARTED: Add your lye solution to your soaping oils. Stick blend until emulsified.

Once you have reached an emulsified state, add the titanium dioxide (predisperse it in oil or water, depending on the type you have). Split your batch in quarters. Each quarter to it’s own mixing cup, and then stir to incorporate the colorants in each.

LAYER IT UP: Starting with the red soap, start pouring! Pour three quarters of the red soap into the mold, and then add one quarter of the pink soap to the red soap. Pour the next layer, emptying the cup of all pinkish red soap.

Take the remaining pink soap, and pour half of it into the mold. Add a quarter of the purple soap to the pink soap, and pour the next layer, emptying the pink soap cup.

Take the remaining purple soap, and pour half of it into the mold. Add a quarter of the blue soap to the purple soap. Pour the next layer, emptying the cup of all purple soap.

Top off the batch with the remainder of the blue soap.

FINISH IT UP: Texture the top & sprinkle with white mica, pink mica, and purple mica. Plus a little dash of Diamond Dust! (Everything’s better with glitter!)

After 24 hours, remove from the mold, slice it up, and give it a good cure. Enjoy!

  1. What a beautiful soap! And I just love the Conservatory and their cheap sample pricing! Just ordered the mica’s for this pretty soap! I think I am going to try and substitute Sweet Almond Oil for the Apricot oil & Hazelnut Oil for the Avo. Oil since that is what I have on hand = )…Does the mica on top of the soap stay in little spots like that or do they migrate easily? Thanks for the great tutorial!
