This fun cold process soap swirling technique creates stunning bars of soap! This is called a drop swirl because you simply fill your mold with a base and then drop soap into it. (Check out the video to see what I mean.) I’ve never tried a black base before; I always swirl into white. I love the results!

I call it a flowerbomb design because some of the pieces look like a messy bouquet of flowers. πŸ™‚

Flowerbomb Drop Swirl Soap Recipe

  • Coconut Oil – 306 grams (34%)
  • Shea Butter – 45 grams (5%)
  • Olive Oil – 360 grams (40%)
  • Avocado Oil – 54 grams (6%)
  • Rice Bran Oil – 135 grams (15%)
  • Sodium Hydroxide – 128 grams
  • Distilled Water – 256 grams
  • Voodoo Mica (Mad Oils) – 1/2 teaspoon
  • Flirt Mica (Mad Oils) – 1/2 teaspoon
  • Voodoo + White – 1/4 + 1/2 teaspoon
  • Charcoal – 2 teaspoons
  • Lavender Essential Oil – 30 grams

Step 1 – Create your lye solution. Set it aside to cool down.

Step 2 – Weigh out your solid oils (coconut oil + shea butter) and melt.

Step 3 – Weigh out your liquid oils and add them to your melted oils. This will cool the temperature down.

Step 4 – Add your slow-moving essential oils or fragrance oils to the melted oils.

Step 5 – Let your oils and lye solution cool to under 90 degrees F. so that you have time to swirl.

Step 6 – Emulsify your soap. Don’t stir to trace or you might not have enough time to swirl.

Step 7 – Divide your soap out into your base and four colors for swirling.

Step 8 – Color your base using charcoal and color each swirling color using the mica.

Step 9 – Pour the base into your mold.

Step 10 – Rotating through your colors, pour them into the mold as shown in the video.

Step 11 – Let your soap saponify overnight.

After 24 hours, cut your soap and let it cure for 4 weeks.
