Making Coffee Soap with 10 ingredients: - Sunset Soap Co.

If you’re just like me and love coffee, this coffee soap recipe is for you. It’s made with an amazing blend of plant based oils and even coffee, which is extracted from freshly-roasted coffee beans. 

This recipe makes about 10-11 bars of soap using a 10 inch silicone mold.

This takes a moderate amount of skills and effort and typically it takes me about 45 - 60 minutes to make this recipe. 

Ingredients

10″ Silicone Loaf Mold
13.9 oz. Olive Oil (42%)
8.3 oz. Coconut Oil (25%)
8.3 oz. Palm Oil (25%)
1.7 oz. Coffee Butter (5%)
1 oz. Coffee Oil (3%)
5 oz. Brewed Coffee
5 oz. Distilled Water
4.6 oz. Sodium Hydroxide Lye
2 Tbsp. Used Coffee Grounds
Whole Coffee Beans (for the top)
Optional: Crinkle Cutter

Instructions

SAFETY FIRST: That means wear goggles, gloves, and long sleeves. Make sure kids, pets, other distractions, and tripping hazards are out of the house or don’t have access to your soaping space. Make sure your soaping area is well ventilated.

COFFEE LYE PREP: Brew 7-8 ounces of coffee using distilled water. Some will evaporate, so you'll need to brew extra. The strength of the coffee is up to you - the stronger it is, the darker your soap will be. 

Measure 5 ounces of coffee into a heat-safe container. Add 5 ounces of cold or room temperature distilled water to the coffee.

 

1

Once your liquid is room temperature or below, slowly add 4.6 ounces of sodium hydroxide lye to the coffee and gently stir until the lye flakes are fully dissolved. The solution will start to darken and smell quite unpleasant - this is normal! Luckily, the scent goes away in the final bars. 

Pro tip: When the lye mixture cools to around 150° F, add 2 teaspoons of sodium lactate to harden the bars more quickly.

2

Fully melt and combine 8.3 ounces of coconut oil, 8.3 ounces of palm oil, 13.9 ounces of olive oil, 1.7 ounces of coffee butter, and 1 ounce of coffee oil. Once the lye water and the oils have cooled to 130° F or below (and are ideally within 10 degrees of each other), add the lye water to the oils and stick blend until it’s at a thin trace. Thin trace the soap looks more like a runny cake batter.

3

Continue to stick blend the soap until you reach a medium trace. Medium trace is perfect for suspending the coffee grounds and creating texture on top. When the soap is at medium trace it starts to look like pudding.

4

Add 2 tablespoons of used coffee grounds to the soap and use a whisk to fully incorporate them.

5

Pour the soap into the mold. Tap the mold firmly on the counter to get rid of bubbles.

6

Use a spoon to mound the soap in the center and create texture. There is no right or wrong way to do this, so have fun with it!

7

Place coffee beans in the center of the soap down the length of the mold. Gently pressing the beans into the soap will help them stick better. Once you’re happy with the look, spritz the top with 99% isopropyl alcohol to prevent soda ash. Allow the soap to stay in the mold for about 2-3 days. Un-mold, and cut into bars. Allow the bars to cure for 4-6 weeks and enjoy!
