Equipment
- Digital Scale
- Safety goggles and gloves
- Stick blender
- Heat-resistant glass or stainless steel bowl
- Soap mold
- Plastic wrap
- Thermometer
- Silicone spatula
- Measuring cups and spoons
Materials
- 95 grams goat milk frozen into ice cubes
- 95 grams water
- 70.31 grams lye sodium hydroxide
- 125 grams olive oil
- 125 grams coconut oil
- 150 grams beef tallow
- 75 grams shea butter
- 25 grams castor oil
- 15.50 grams essential oils optional
Instructions
- Pour lye into water, slowly, stirring in between each pour.
- Stir until the lye is completely dissolved, and then set the jug aside to cool to 100°F.
- When the lye has cooled, add the goat milk cubes. Cool to 68-72 degrees.
- As soon as you add the goat milk to lye water, melt the solid oils over low heat, stirring constantly.
- As soon as they’re melted, remove from heat and add the liquid oils [by pouring them against the back of a spoon to prevent bubbles]. Cool the oil mixture to 90 degrees.
- Slowly add the lye water to the oils [pour against a spoon to prevent bubbles].
- Place an immersion blender into the oil mixture and use it (turned off) to stir the contents together. Then hold the stick blender still, and pulse for a couple of seconds. Repeat the stirring and pulsing process until the mixture begins to thicken. You'll know it's ready when the consistency reaches that of warm custard and you see trails forming on the surface of the oil mixture.
- Add your essential oils and pulse a few more times to incorporate.
- Pour the soap into the mold.
- Cover with plastic wrap and put in fridge for 24-48 hours. Then remove from fridge but leave in mold to cure for 3-4 more days.
- Remove from mold and cut into bars. Even after curing for a few days, this soap will be soft! Let it cure for at least 4 more weeks before using.
Notes
This recipe includes a 5% superfat, meaning there’s more oil than lye and 5% of the oils are left unsaponified, providing extra moisturizing properties.
