Book 3. Soap Making: Essential Guide For Absolute Beginners. 20 Homemade Organic Recipes
Chapter 11. Fragrant Coffee Soap
19 ounces double strength coffee, room temperature
8 ounces lye
21 ounces olive oil
9 ounces palm kernel oil
12 ounces coconut oil
3 ounces castor oil
6 ounces jojoba oil
9 ounces macadamia nut oil
Step 1: Add the lye to the coffee
Instead of water, for this soap, you’ll use double strength coffee. Carefully add the lye, stirring continuously. Set the mixture aside to cool.
Step 2: Mix the oils
Combine all the oils in a glass or stainless steel bowl. Heat in a microwave until the temperature reaches 90F.
Step 3: Blend
When the temperature of the coffee mixture is also 90F, pour it into the bowl with the oils. Use a stick blender to combine the mixtures.
Step 4: Molding
Once you reach trace, pour the mixture into molds and leave to harden. This will take a day or two.
Step 5: Cut into bars
Unmold the soap and cut it into bars. Leave to cure for 4 to 6 weeks. The best option is to keep the bars in a well-ventilated area.
