Lime in the Coconut Milk Cold Process Tutorial
Recipe type: Cold Process
Serves: About 3 pounds of soap
This Lime in the Coconut Cold Process Soap uses coconut milk instead of water for a fluffy and rich lather.
  • Tall 12" Silicone Loaf Mold
  • 1.9 oz. Avocado Butter
  • 1.9 oz. Castor Oil
  • 11.1 oz. Coconut Oil
  • 5.6 oz. Green Tea Seed Oil
  • 1.9 oz. Mango Butter
  • 14.8 oz. Olive Oil
  • 5.2 oz. Sodium Hydroxide Lye
  • 1.5 oz. Coconut Milk Powder
  • 12.3 oz. Distilled Water
  • Chrome Green Oxide
  • Fizzy Lemonade Colorant
  • Titanium Dioxide
  • 1 oz. Lime Distilled Essential Oil
  • 1 oz. Coconut Lemongrass Fragrance Oil
  • Citrus Slice Wax Tart Mold
  • 2 oz. Clear Melt and Pour Base
  • Yellow Lip Safe Mica
  • Chrome Green Color Block
Make the Embeds
  1. Cut and melt 2 ounces of clear melt and pour base in the microwave using 5 second bursts. It’s easy to burn such a small amount of melt and pour, so using small bursts helps avoid this. Add small shavings of the Chrome Green Color Block and stir until a rich green color is achieved. Carefully pour the soap into each cavity until the citrus shape is covered; don’t fill the cavity all the way. Spritz with alcohol to disperse any bubbles. Allow to fully cool and harden.
  2. Remove each embed from the mold. Use a paintbrush to lightly dust the lime shape with Yellow Mica. This step is optional, but the mica really helps the details pop! Set embeds aside.
Make the Cold Process Soap
COLOR PREP: In separate containers, disperse 1 teaspoon of the Chrome Green Oxide into 1 tablespoon of sunflower or sweet almond oil (or any other liquid oil). Then, in separate containers, disperse 2 teaspoons of the Fizzy Lemonade Colorant, Titanium Dioxide of light liquid oil. Use a mini mixer to get the clumps of color worked out smoothly.
FRAGRANCE PREP: Mix 1 oz. of the Coconut Lemongrass Fragrance Oil and 1 oz. of the Lime Essential Oil. Set aside.
MILK PREP: Mix 1.5 oz. of coconut milk powder into the distilled water. When using this Coconut Milk Powder we found it was a little tricky to mix into water however, heating the water slightly (to about 95°F) made it easy. Once the powder is completely mixed into the water and contains no clumps, pour the milk into ice cube trays and place them into the freezer until completely hard (several hours to overnight).
  1. Remove the fully frozen milk from the ice cube trays and place into a container that has been placed in an ice bath. Slowly add lye and stir until the lye is fully dissolved and the milk has become liquid. Click here to see this process and more tips on creating a lye and milk mixture. If you’d like a harder bar of soap that releases faster from the mold, you can add sodium lactate to the cooled lye milk. Use 1 teaspoon of sodium lactate per pound of oils in the recipe. For this recipe, you’d add about 2 tsp. sodium lactate.
  2. Fully melt and combine the coconut, olive, green tea seed, castor, avocado butter and mango butter. Once the oils have cooled to 130 degrees or below, add the lye milk to the oils and stick blend until thin trace.
  3. Pour off two containers, each measuring 1 cup. The large container should then hold about 4 cups.
  4. To the large container, add 2 tablespoons of the dispersed Fizzy Lemonade Colorant, and 1 tablespoon of the dispersed Chrome Green Oxide. Use a whisk to fully incorporate.
  5. To one of the smaller containers, add 2.5 tablespoons of dispersed Fizzy Lemonade Colorant and use a whisk or spoon to fully incorporate. To the other small container, add 2 tablespoons of the dispersed titanium dioxide and use a whisk or spoon to fully incorporate. Add the fragrance oil blend proportionally to each container (it’s okay to eyeball it!) and use a whisk to fully combine.
  6. Pour the entire container of green soap into the mold, and tap the mold firmly on the counter to help get rid of any air bubbles. Don’t scrape the bowl clean, leave a small amount of green soap in the bowl for the top.
  7. Pour half of the white soap into the center of the mold. Pour from about 10 inches above the mold; this helps the white soap drop into the green soap, rather than sitting on top and creating layers.
  8. Pour the yellow soap into the green and white soap. Pour the yellow soap from 8-10 inches above the mold to ensure the yellow soap breaks through into the green soap. Leave a small amount of soap in the container for the top.
  9. Tap the mold firmly on the counter to help get rid of air bubbles. Stick blend the leftover white soap until you reach a thick trace.
  10. Use a spoon to gently place the thick white soap on top of the green soap. Gently spread the soap to ensure an even layer.
  11. Use a spoon to place the leftover yellow soap from the container onto the white.
  12. Place any leftover green soap onto the yellow, and use a spoon to create peaks and texture with the yellow, white and green soap.
  13. Place the lime embeds into the side of the soap. Ensure the lime is far enough in the soap that they don’t fall out.
  14. Spritz the top with 99% isopropyl alcohol to prevent soda ash, and place the soap into the freezer for 24 hours. Doing so prevents the soap from going through gel phase which will scorch the coconut milk. After 24 hours, remove the soap from the freezer and allow to sit in the mold for 3-4 days. Milk soap can be a little softer due to the extra milk fat. Patience is key! Remove from the mold, cut and allow to cure for 4-6 weeks.
