Slowly and carefully add 4.9 ounces of lye to 10.4 ounces of distilled water. Gently stir until the lye has fully dissolved. Set it aside to cool. If you’d like a harder bar of soap that releases faster from the mold, you can add sodium lactate to the cooled lye water. Use 1 teaspoon of sodium lactate per pound of oils in the recipe. For this recipe, you’d add 2 teaspoons sodium lactate.

Melt and combine 3.5 ounces of avocado oil, 1 ounce of castor oil, 8.8 ounces of coconut oil, 8.8 ounces of olive oil, 8.8 ounces of palm oil (remember to fully melt the entire container of palm oil before portioning), and 4.2 ounces of rice bran oil into a large mixing bowl. Once the lye water and the oils have cooled to 130 degrees F or below (and are ideally within 10 degrees of each other), add the lye water to the oils and stick blend the mixture to a very thin trace.

Split the soap into 3 separate containers and add the following colors. Use a whisk to mix them in.

• Container A (300 mL ): 1.5 teaspoons dispersed Caribeen Blue Mica

• Container B (300 mL): 2 teaspoons dispersed Ultramarine Blue Pigment

• Container C (remaining soap): All dispersed titanium dioxide

Add the 1.75 ounces of Fresh Snow Fragrance Oil to each container proportionally – it’s okay to eyeball it. Use a whisk to mix in the fragrance.

Pour a small amount of the white soap into the mold – just enough to cover the bottom. Then alternate pouring small amounts of the dark blue, white, and light blue soap into the mold at varying heights. That helps the soap drop to different areas of the mold rather than sitting on top and creating layers. Don’t worry about being too precise when you’re pouring.
Tip: Pouring white soap between the two shades of blue helps define the swirls. 

Continue pouring the soap into the mold. Save a very small amount of each color for the top.

Insert the Hanger Swirl Tool into one side of the mold. Then, use loop-de-loop motions to swirl the soap. There is no right or wrong way to do this necessarily, but different motions and patterns will result in slightly different looking swirl. Some loops should be big and some small. Varying the direction (horizontal versus vertical) also creates a more complex swirl. Once you’ve swirled the soap about 7-10 times, remove the Hanger Swirl Tool by bringing it up and out on one side of the mold.

Pour or plop (depending on your trace – ours was quite thick at this point) dollops of the remaining soap on top. Don’t worry too much about the placement of each color.

Use the back of a spoon to create peaks and divots into the soap. Have fun with the texture – there is no right or wrong way to do it.

Once you’re happy with the top, spritz with 99% isopropyl alcohol. We placed this soap on a heating pad for about 1 hour to help promote gel phase. Allow the soap to stay in the mold for 1-3 days (depending if you used sodium lactate or not). Unmold and cut into bars. Allow the bars to cure for 4-6 weeks and enjoy!
