This goat milk shampoo bar recipe combines the nourishing benefits of goat milk with natural oils and essential oils, creating a luxurious and eco-friendly alternative to traditional liquid shampoos.
You’ll need to freeze the milk. To do so, weigh out the amount of milk you need for the recipe directly into ice cube trays. Freeze until solid.
241 g Goat’s Milk
Place the frozen goat’s milk and water in a heavy-duty plastic or stainless steel bowl. Wearing protective gloves and eyewear, carefully sprinkle a small amount of lye at a time over the frozen milk, stirring well after each addition.
14 g Water, 111 g Sodium Hydroxide
Melt the coconut oil and shea butter, then add them to the other oils. Add the lye/milk solution to the oils. Using a combination of hand stirring and an immersion blender, stir the soap until it reaches a very light trace.
213 g Coconut Oil, 85 g Shea Butter, 298 g Olive Oil, 85 g Sweet Almond Oil, 113 g Castor Oil
At trace, stir in essential oil, if using, then pour into a prepared mold.
35 g Lavender Essential Oil
Let the soap stay in the mold for 24 hours. The next day, you’re ready to unmold and slice into bars.
Notes
It is safe to use your soap after a few days, but I recommend putting the soap somewhere cool, dry, and with good airflow for four to six weeks. The extra water will evaporate, making the bars harder, so they last longer in the shower.
