Cold Process Coffee Soap

Have you heard of the caffeine soap craze? There are products out there that market a soap with so much caffeine in the bar that just taking a shower it equal to a cup of coffee. This very likely isn't true, but you sure can get an early morning pick up if you love the smell of coffee and putting coffee grounds into your bar is a gentle way to incorporate an exfoliating side.

Cold Process Coffee Soap

Being a coffee addict, this was one of the first recipes I made multiple times. Now, the reason I was so eager to try this was because I had a girlfriend who swears that coffee does something to break up cellulite underneath your skin. Of course, with my google powers, I couldn’t verify that, but people really do pep up when you offer coffee grounds as an exfoliate. Some claim when it comes to caffeine in your skin care products you can get a stimulating effect that will draw blood to the surface of the skin and create a pink glow. Others say that you will absorb the caffeine through your skin and feel awake and vibrant. In any case, remember you probably shouldn't be trying to absorb anything into your body that isn't approved by the FDA, and soap washes right off your skin so contact is minimal. If it's coffee you love, this is a fun bar. If it's a morning perk you want, aroma therapy might do a better job. This recipe is a 5 lb. Recipe. It will yield 16-20 bars cut into 4/4.5 oz. I like to make this recipe in the slab mold so that the bottom flat side of the bar is covered in coffee grounds for exfoliate. Cut this recipe in half for a 2.5 lb bread mold size recipe, or run it through the Thermal Mermaid soap calculator for the 3 lb. recipe

  • Brewed Coffee 7 oz.

  • Water 7 oz.

  • Lye 7.3 oz. (3.65/3.65)

  • Coconut Oil 18.5 oz.

  • Lard 15 oz.

  • Vegetable Oil 11.5 oz.

  • Olive Oil 15 oz.

  • Castor Oil 7.3 oz.

  • Shea Butter 2.5 oz.

  • Coffee Grounds

  • Coffee Fragrance 2.5 (optional)

  • ½ tsp. Titanium dioxide

This is an easy standard cold process method. You will make this bar like all your other cold process batches.

However, here when you mix your lye solution you will substitute ½ of the water for brewed coffee. Make sure you have put your coffee in the refrigerator to cool down. You may find the best luck if you put it in the freezer and make a slush out of it. (Don’t brew your coffee fresh and pour your lye crystals into hot coffee. It could bubble up violently.) Mix the lye water solution in 2 parts. 1 part is coffee water/lye and the second part is water/lye. Allow these to relax and reach room temperature.

Mix your oils. Split the oils into 2 separate bowls. Mix the coffee/lye solution into 1 part of the oils. Sprinkle a thin layer of coffee grounds in the bottom of your mold. Add 1.25 oz fragrance oil.

Tip: These grounds should be the ones that you've already processed. If you use fresh grounds the finished soap can stain the surface of a counter or dish if its set down while wet. The used grounds will give you the coffee texture without bleeding actual coffee into whatever it touches. Fold the remaining grounds into the soap and pour the bottom half of the slab.

Mix the lye water solution and the oils for the second half of the slab. Add ½ tsp. Of titanium dioxide to whiten the soap and 1.25 oz. Of fragrance oil. Gently spoon this on top with a texture. Dust the top with coffee grounds and full beans.
