Some recipes for homemade soaps that do not use lye include soap bars made with goat milk, soap bars made with liquid castile soap and a multi-layered soap bar made with glycerin. Other homemade soap recipes that do not use lye include lavender and herbal soaps.
To make a bar of goat milk soap without using lye, first melt one bar of glycerin soap in a double-boiler or microwave, then stir two tablespoons of goat milk powder into the melted glycerin and combine over low heat. Next, add 4-5 drops of an essential oil and 5-6 drops of food coloring and mix until well blended. Spread petroleum jelly over the soap molds, fill them with the soap mixture and spray the tops of the molded soaps with rubbing alcohol. Allow the soap to cool completely before removing it from the molds and wrapping it in plastic.
Spraying the tops of lye-free homemade soap bars with rubbing alcohol while they are still in their molds helps to prevent air bubbles from rising to the top of the bars. Another tip for making homemade soap without lye is to make it when it is not humid outside; otherwise, it may be more difficult for the soap to set. In addition, homemade soap made without lye must be allowed to dry out for three weeks before use to ensure the bars are hard enough. This long drying-out process also enables the soap to last longer.
