(Original) Basic Goat Milk Soap Recipe
Recipe Instructions
Important notes before beginning:
- Before beginning - mix together your powdered Goat milk with warm water (1 oz. of powdered goat milk to 8 oz. warm water) place into ice cube trays and freeze before measuring out weight for recipe/ usage.
- Mix 1 tsp. of mica with 1 tbsp. of sweet almond oil or avocado oil to make the addition of colorants easier
- Gather all the ingredients together and arrange them on the table in the order in which they appear in the recipe. *I set out my goatmilk cubes to start melting slightly to make them easier to pop out of the ice trays as I pre-measure out my butters, oils, colorants and additives.
- Measure the lye either in a lye safe container or stainless steel bowl and set aside
- Measure out 12.66 oz of goat milk ice cubes into a lye safe container that is large enough for mixing your lye/water/milk solution. Place the container on a heat resistant surface and add a small splash of distilled water to the ice before adding the lye to the ice cubes. This helps the ice cubes start melting more evenly and helps prevent scorching the milk. Slowly add the lye stirring between each addition. Stir until all the lye is completely dissolved and all ice cubes are melted. Optional: Add 2 teaspoons of sodium lactate to help the bars harden more quickly
- Fully melt and combine coconut oil, palm oil, olive oil pomace, sweet almond oil, and castor oil. Once the oils have cooled to 130° F or below add the lye solution slowly to the oils and begin pulsing your stick blender.
- Continue to blend to reach low-medium trace
- Add your fragrance oil, and quickly blend or hand stir in. Add colorant of choice and stir until incorporated.
- Pour the soap into the mold. Tap it firmly on the counter to eliminate air bubbles, and use a spoon or spatula to spread the soap evenly into the mold.
- Spray the top with 99% isopropyl alcohol to help prevent soda ash. Let it sit 3-4 days. If you find the silicone liner is not pulling away from the sides of the mold easily, give it another day to harden. Remove the soap from the dividers and allow the bars to cure for 4-6 weeks.
Additional Notes:
SAFETY FIRST: Suit up for safe handling practices. That means goggles, gloves, and long sleeves. Make sure kids, pets, other distractions, and tripping hazards are out of the house or don’t have access to your space. Always make soap in a well-ventilated area.
LYE PREP: With safety gear on, slowly add about ¼ of the lye flakes to the frozen goat milk. Use a stainless steel spoon to stir. Slowly, the flakes will begin to melt the goat milk cubes. After a few minutes of stirring, add another ¼ of the flakes and stir for several minutes. Continue this process until all the lye flakes have been added. Once the milk has fully melted, keep stirring to make sure all the lye flakes have completely dissolved. Because the temperatures are low, the lye flakes do not dissolve as quickly. Patience is key!
Below, our milk reached about 90° F and developed a very slight yellow color. That's fine for this recipe. If you want a lighter shade, place the container in an ice bath to keep it extra cold. Optional: Add 2 teaspoons of sodium lactate to help the bars harden more quickly.
COLORANT PREP: Disperse 3 teaspoons of titanium dioxide into 2 tablespoons of lightweight liquid oil, like sweet almond oil or sunflower oil. Optional: To ensure the titanium dioxide blends smoothly into the soap, we recommend micronizing it before dispersing it in oil. Use a coffee grinder to break up any clumps of color and prevent streaks of white from showing in the final soap. We like to use a coffee grinder that has a removable stainless steel mixing area for easy cleaning.
