Do you LOVE coffee? Need that jolt of caffeine to get you moving in the morning? Did you know that your skin loves coffee too? Coffee is a great source of antioxidants. Washing with a coffee soap helps get those age defying antioxidants into your skin to wash away toxins and cleanse your pores.

Caffeine might be a stimulant when you drink it, but on your skin it has a soothing effect. It’s great for sensitive or sunburned skin. The caffeine constricts blood vessels, so it can help with the appearance of rosacea or redness. Caffeine has also been shown to help with the appearance of cellulite by dehydrating underlying fat cells.

When you add coffee grounds to the soap it provides an excellent exfoliant to help sloth off dead skin layers, leaving your skin soft & younger looking. Coffee grounds also have a natural deodorizing effect so it’s a great soap to keep in the kitchen to wash cooking smells off your hands. Have I convinced you yet? Then let’s get started!

Before getting started, if you have never made soap before, check out my Basic Soap Making post. We will be working with lye, which can be very dangerous. Make sure you are taking proper safety precautions. Once the lye and oils have saponified, no lye will remain in the soap and all that will be left are skin loving oils & coffee.

This recipe will have 25 oz of oil with an 8% superfat.  If you make any substitutions with the oils make sure you run the recipe through a soap calculator.

Ingredients:

9.5 oz brewed coffee (cooled to room temperature)
3.4 oz sodium hydroxide (lye)
6.25 oz Coconut Oil
6.25 oz  Olive Oil
6.25 oz Palm Oil
3 oz Avocado Oil
2 oz Shea Butter
1.25 oz Castor Oil
2 TBSP ground coffee
Essential Oil or Fragrance Oil

Equipment (all equipment should only be used for soap making):

1 large & 1 medium bowl
1 bowl for an ice bath
small bowls
immersion blender
gloves, eye protection &
 face mask
digital thermometer
spoons
digital scale
10 inch silicone mold or other soap mold

Instructions:

Start by brewing your favorite coffee and allowing it to cool to room temperature.  Do not add anything (like cream or sugar), just regular, black caffeinated coffee.  Every New Englander knows Dunkin has the best coffee, so I am using Dunkin Donut’s Original Blend coffee 🙂

While your coffee is cooling, blend the essential oils together in a small bowl.  The blend I used was 0.33 oz coffee, 0.20 oz cinnamon, 0.15 oz clove bud, & 0.15 oz nutmeg essential oils for a warm spicy coffee scent, but you can use whatever blend you like, or a coffee fragrance oil.  Brambleberry has an Espresso fragrance oil that would be perfect.

Pour the cooled coffee into a medium bowl.  Carefully measure the lye and slowly add it to the cooled coffee.  Remember to use your safety equipment!  Put the lye coffee bowl in an ice bath (larger bowl filled with cold water & ice) and stir until lye is totally dissolved.  Alternately, you can freeze the coffee in an ice cube tray ahead of time and add the lye to your coffee cubes.

When you add the lye, it will heat the coffee very quickly.  The ice bath (or coffee cubes) will keep the temperatures down so you don’t end up with a burnt coffee smell in your finished soap.  Set the lye coffee mixture aside.  The lye coffee will likely smell pretty terrible, don’t worry.  I promise as long as you keep the temps down (under 170 degrees is ideal, but the lower you can keep the temp the less smell there will be), that smell won’t transfer to the final product!

Measure out the Coconut, Olive, Palm, Shea, Avocado & Castor oils into the large bowl.  Microwave oils for 40 seconds, stir, then microwave another 40 seconds.  By now the oils should be all liquid (if they aren’t, put them back in for another 20-30 seconds).  Alternately, use a double boiler to melt the oils on the stovetop.  Set the oils aside to cool.

Check the temperature of your lye coffee.  If it’s 100 degrees or lower, you can take it out of the ice bath.

You want both the lye coffee & oils to be between 90-100 degrees.  When soaping with food products, it’s best to soap with colder temperatures.  While they are cooling, I like to put all my oils away, tidy up my workstation and get my soap mold ready to go.

Once the lye coffee & oils are the right temperature, slowly add the lye coffee to the oils.  Using your immersion blender, blend until you reach a medium thick trace.  Add the essential oils and stir them in by hand.  You want the soap mixture to be thick enough that it will suspend the ground coffee.  Once you have the right consistency, add the ground coffee and stir in by hand.

Pour the mixture into your soap mold.  Tap gently against the counter to get rid of air bubbles.  I used a toothpick to add a little bit of texture to the top. When I make soap with a food product I leave the soap mold uncovered and put it in the refrigerator overnight to prevent overheating.  Coffee doesn’t have as much natural sugar as other food products I soap with (like goat or coconut milk, or honey), so refrigerating it might be overkill but I do it anyway.  After about 24 hours, unmold your soap.  Cut the bars and allow them to cure for 4-6 weeks.

    1. I’ve done it both ways and the soap came out just fine either way. But keeping the temperatures cooler definitely makes for an easier soap making process 🙂
