If you’ve never made Cold Process soap before, stop here! I highly recommend checking out our FREE four part SoapQueen.tv series on Cold Process Soapmaking, especially the episode on lye safety. And if you’d rather do some reading, Bramble Berry carries a wide range of books on the topic, including my newest book, Pure Soapmaking. You can also checkout the digital downloads for that instant gratification factor.

SAFETY FIRST: Suit up for safe handling practices! That means goggles, gloves and long sleeves. Make sure kids, pets, and other distractions and tripping hazards are out of the house or don’t have access to your soaping space. Always soap in a well-ventilated area.

FRAGRANCE PREP: Measure 1.7 ounces of orange 10X essential oil into a glass, fragrance oil safe container. Set aside.

ONE: Slowly and carefully add the lye to the water and gently stir until the lye has fully dissolved and the liquid is clear. Set aside to cool.

TWO: Melt and combine the coconut oil, cocoa butter, castor oil, palm oil, and olive oil (remember to fully melt then mix your entire container of palm oil before portioning). Once the lye water and the oils have cooled to 130 degrees or below (and are ideally within 10 degrees of each other). Place 5 tablespoons of pumice in a small container, and add 5 tablespoons of the soaping oils into the container and mix together. Doing so helps get rid of clumps, without adding too much extra oil into the soap. Set aside.

collageTHREE: Add the lye water to the oils and stick blend until thin trace. 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 about 2 teaspoon sodium lactate.

THREE

FOUR: Once you’ve reached a thin trace, add the orange 10X essential oil and use the stick blender to mix in. Alternate using short bursts and stirring with the blender to avoid over stick blending.

FOURFIVE

FIVE: Add the pumice mixture into the soap, and use the stick blender to mix in. This will cause the mixture to thicken.

SIX

SIX: Add 8 tablespoons of walnut shells and use a whisk to fully mix in.

SEVEN

SEVEN: If your batter is thin enough to pour, fill each cavity evenly. My batter was quite thick thanks to the additives and water discount, so I used a spoon to fill each cavity. Tap the mold firmly on the counter to help eliminate the air bubbles (make sure those goggles are on; beware of splashing soap when tapping). Spritz the soap with 99% isopropyl alcohol to help eliminate soda ash.

EIGHT

Allow the soap to stay in the mold for about 2-3 days. Unmold, and allow to cure for 4-6 weeks. I used the Soap Shaver to clean up the sides and top of the soaps, but this is optional.
