Materials Needed For This Coffee Soap For all cold process soap recipes, there are a few materials that are always needed. Some of these are common around a house and others will need to be purchased specifically for soap making. Soap Loaf Mold (this recipe will fill one of these molds to the top, providing you with approximately 10, 4 ounce bars.) Soap Cutting Box/ Tools (you can use a knife and cutting board but the bars may not be even. I also love the look of the wavy soap!) Kitchen Scale (this doesn’t have to be fancy but it is a requirement to properly measure soap. If you do not use the exact amounts of oils and lye, the soap may burn you.) A Large Mixing Bowl (you do not want any of the soap overflowing!) An Immersion Blender (I am sure you could technically mix a soap batter by hand but it would take so much longer to reach trace.) Gloves (to protect your hands and keep things sanitary.) Eye Protection (to ensure nothing splashes into your eyes and potentially blinds you.) PH Testing Strips (to ensure a safe bar.) Fine Mesh Strainers (to remove the large coffee grounds) ✅ Get the Free Guide Loading… Thank you! Check your email for a link to the PDF download What Ingredients Are In this Coffee Soap?

There are some steps that can greatly decrease the risk you take and I will outline them for you here. ALWAYS wear eye protection. In the horrible event the lye water or soap batter splashes up at you, you want to make sure you will not get it into your eyes. Know what the MSDS says. Some people will tell you to keep an acid (such as vinegar) close to you in the event any lye gets on you. The MSDS disagrees heavily and instead tells you to focus on flushing the area with WATER for at least 15 minutes. Always seek medical care after you flush. ALWAYS keep your body covered. This means gloves, long sleeve shirts, full pants and shoes. You do not want there to be an opportunity to splash onto bare skin. Pour the lye into a heat safe container that has a lid such as a pyrex storage container and make sure the lid stays on the whole time. Always use lye in a well ventilated area. It creates a lot of fumes that can damage your lungs. It is also an exothermic reaction, meaning it creates heat so be careful when moving the lye mixture. Pour the lye into the water or in this case, coffee and never the other way around. {Related: Easy Tallow Soap Bar That Works for Everything} How to make the coffee soap The night before you intend on making the soap, brew a very strong pot of coffee.

How to strain the coffee from the oils 5. When the coffee oil has a fragrant smell, remove it from the heat using oven mitts and allow it to rest until it has cooled down and you can safely touch the bowl without a burn. Make sure the oils stay liquid though. 6. Add a fine mesh strainer to a secondary bowl and pour the contents of the first bowl, through the strainer into the second bowl. This will allow the small pieces of coffee to remain in your batter as a gentle exfoliant but will remove the large pieces that could scratch you. 7. Return the mix to the double boiler over low heat to re warm. Making the lye
