To make goat's milk soap, combine goat's milk, lye, olive oil, coconut oil, castor oil, rice bran oil, shea butter and sweet almond oil. Other required supplies include a large mixing bowl, a medium mixing bowl, silicone soap molds, water, ice cubes, rubber cleaning gloves, a silicone spatula, a wooden spoon, measuring cups, a metal cooking pot and a stove. It takes about 30 minutes to make one batch of soap.
- Prepare an ice water bath
Place a handful of ice cubes in the large mixing bowl, and add several inches of water.
- Combine the goat's milk and lye
Put on rubber cleaning gloves. Pour 18 ounces of goat's milk into the medium mixing bowl. Set the bowl in the ice bath, and stir the milk with a silicone spatula. Gradually add 9 ounces of lye, and stir continuously until the lye powder dissolves.
- Heat the solid oils
Set a metal pot over medium heat. Add 20 ounces of coconut oil and 5 ounces of shea butter. Stir the mixture until it liquefies, and then remove it from the heat. Add the liquid oils in the following amounts: 20 ounces of olive oil, 4 ounces of castor oil and 5 ounces each of rice bran oil, avocado oil and sweet almond oil.
- Stir the soap
Pour the goat's milk mixture into the oils. Stir the soap with a silicone spatula until it cools and thickens.
- Pour the soap into the molds
Pour the soap into silicone molds, and leave them to set for 24 hours.
- Remove and cure the soap
Remove the soap from the molds, and slice it into rectangular bars. Cure the bars for four weeks before using them.
