CBD Soap Recipes to Try at Home

Did you know you can use CBD on your skin? Because the skin has CBD receptors it’s able to absorb CBD compounds, making it one of the four routes of absorption. And since it’s absorbed so effectively through the skin, CBD is an ideal ingredient in creams, lotions and bath bombs.

Another popular way to deliver CBD to the body is with CBD soap. People have started becoming more aware of the importance of using soap that is nourishing and easy on the skin. This requires using ingredients that are natural and healthy, like CBD oil. The best part is that making your own CBD-infused soap isn’t hard to do. In fact, there are a few different simple recipes for making homemade CBD soap which we’ll discuss in this post.

How CBD Soaps Work

When we use topical CBD products, the cannabinoid receptors on our skin absorb the CBD compounds, energizing our endocannabinoid system (ECS). This produces homeostasis in our minds and bodies that may generate a sense of balance and calmness.

By creating a DIY CBD soap, you have the freedom to customize them to your personal needs. Homemade soaps are usually a vibrant and healthy mix of other types of natural oils as well, like coconut and essential oils, which each carry their own scents and unique benefits.

Using CBD Oil in Your Recipe: Things to Keep in Mind

Before we dive into our recipes, it’s important to discuss a few significant factors about adding CBD oil to your soap.

Finding Quality CBD Oil

When selecting a CBD oil for your recipe, it’s crucial that you look for high-quality CBD products. This requires taking time to research brands and their production methods to ensure that what you’re putting into your body is safe and legitimate. If you’re new to CBD, here are a few key things to look for when choosing CBD oils:

  • It comes from organic, nutrient-rich, and contaminant-free soil.
  • It comes from quality extraction and refinement processes.
  • It’s gone through legitimate third-party testing labs, and you have access to these test results.

Using Saponification & Heat

Saponification (after sapo, Latin for soap) occurs when a solution of lye combines with oils and creates a chemical reaction that breaks the oils down into chains of fatty acids. Heating the lye and oil solution evaporates the water molecules, turning the solution into a solid form, producing bar soap.

Though CBD is known to evaporate under high heat, you won’t have to worry about this when it comes to making your CBD soap. CBD tends to lose its potency at around 300 degrees, but soaps only need to be heated up to about 100 degrees Fahrenheit.

Knowing How Much CBD Oil to Add

Though many CBD soap recipes list a specific amount of CBD oil to use, it’s important to note that every person’s body is different and will respond differently to the cannabinoids in CBD; thus, we can’t say exactly how much CBD oil you should use in your recipe. Finding the right amount of CBD to use will take some trial-and-error. If you already know what your ideal serving of CBD is, you can multiply it by the number of bars of soap you’re making and use that measurement as a starting point.

CBD Bar Soap Recipe with Lye

This recipe yields 12 four-ounce bars, or three pounds of CBD bar soap. It involves using lye, so take extra caution and be sure to wear protective gear.

  • 10 ounces coconut oil
  • 5 ounces cocoa butter
  • 5 ounces shea butter
  • 5 ounces castor oil
  • 5 ounces avocado oil
  • 11.9 ounces filtered water
  • 4.1 ounces lye
  • 1 ounce lavender essential oil (or any essential oil of your choice)
  • Desired amount of CBD oil
  • Soap mold
  • Stainless steel pot
  • Stainless steel spoon
  • Plastic spatula
  • Hand mixer or stick blender
  • Old plastic container (for your lye)
  • Thermometer (a cheap candy thermometer will work just fine)
  • Towels to incubate your mold
  • Protection gear like gloves, goggles, and mask
  1. Combine your coconut, cocoa butter, shea butter, castor, avocado, and CBD oils in a large stainless steel pot. Heat them together on low until they are melted. Stir frequently with your stainless steel spoon and make sure they are combined well. Use your thermometer to make sure the mixture reaches 100 degrees Fahrenheit.
  2. In your plastic container, add your filtered water and then slowly pour your lye into the water (if you pour the water into the lye, the solution can explode). Stir them together with a stainless steel spoon until well combined. This solution will heat up when you combine them, so set this aside after stirring to get it to cool down between 95 and 100 degrees Fahrenheit (use your thermometer to keep track of this).
  3. When both mixtures—oils and lye water—are around 95 to 100 degrees Fahrenheit, pour the lye water into your pot of oils. Blend them together with a hand mixer or stick blender for about two to three minutes or until combined well.
  4. Add your essential oil to the mixture and stir.
  5. Using your spatula, pour the mixture into your soap molds.
  6. Using your towels, cover and insulate your molds for 24 hours.
  7. After 24 hours, remove your soap from the molds, cut them, and let them cure for four to six weeks (turn them occasionally to ensure all sides dry out).

Note: Be very careful handling and mixing the lye; it’s extremely caustic and can cause severe damage if it stays on your skin. It’s recommended that you do this step outside and wear your goggles, mask, and gloves while doing this. Be sure to hold your breath/avoid breathing in the fumes.

CBD Bar Soap Recipe Without Lye

If you don’t feel like involving yourself with lye just yet, we have an easy melt and pour recipe below. This entails melting soap base in your microwave and adding fragrances and CBD.

  • 1 pound of melt-and-pour soap base of your choice (goat milk, aloe, and honey are a few popular choices)
  • Desired amount of CBD oil
  • 0.25 to 0.5 ounces of fragrance or essential oil of your choice
  • Soap-safe colorants and herbal additives like calendula petals to decorate your soaps
  • A heated or butcher’s knife
  • A microwave
  • Spoon or spatula for mixing
  • Soap molds
  • Towels
  1. Chop the soap base up into one to two inch cubes.
  2. Heat the soap base cubes in the microwave in short bursts until most of it has melted. Stir them frequently in between the heating sessions.
  3. When most of the soap has melted, stir in your CBD oil and mix thoroughly.
  4. Add in your optional fragrances/essential oil, colorants, and herbs. Mix until well combined.
  5. Pour the solution into your molds, and let them harden completely. You can use your towels to cover and insulate them.

Be sure to store any extra hardened soap in an airtight container to prevent sweating (due to the natural glycerin content of the soap).

How to make hemp soap

Making your own soap is incredibly rewarding and surprisingly easy. Not only do you get to pick exactly what you want to put in it, but it is much less expensive than buying specialty soaps that might consist of harmful ingredients.


  • Coconut Oil – 6 oz.
  • Cannabis or Hemp Oil – 5 oz.
  • Olive Oil – 5 oz.
  • Water – 4 oz.
  • Lye – 2.32 oz. or 66 grams
  • Essential Oil (optional) – 2 tsp

If you want to make a soap with cannabis oil, you can complement the terpene profile of the cannabis strain you are using by picking matching essential oils. Some examples are: Lemon Kush, best accompanied by lemon essential oil; AK-47 strain, an earthy scent, with frankincense or sandalwood; Burmese Kush, pine scented, matches well with pine essential oil. You can also match cannabis strains with complimenting scents that are less exact, Strawberry Cough would go nicely with lime essential oil.


  • 2 Glass bowls (or 4-cup measuring cup)
  • Wooden Spoon
  • Stick Blender (Hand-mixer)
  • Tupperware for measuring
  • Kitchen Scale
  • Candy Thermometer

Measurements are very important when making soap and need to be done by weight and not volume, so a kitchen scale is essential.

CAUTION: Lye can be harmful to the skin and eyes. Wear protective gear (gloves, long sleeve shirt, pants, shoes, protective glasses) when handling.


Place a glass bowl on your kitchen scale and zero out the weight. Add water and set aside.

In a dry tupperware, measure out the 66 grams of lye. Do not forget to wear protective gear and zero out the scale before measuring.

Using the wooden spoon, carefully pour the lye into the water. Mix well, so the lye does not settle on the bottom of the bowl. It is best to cover your mouth with your sleeve or a towel to prevent inhalation of the vapors. This is the most dangerous part of making soap, so be safe. Once the lye is mixed in well, set aside. It may be wise to use oven mitts for this as the lye gets hot quickly.

In a glass bowl or measuring cup, weigh out the 6 oz. of coconut oil. Add cannabis/hemp and olive oil, until you reach 16 oz.

Slowly heat up the oils in the microwave until the mixed oils’ temperature is between 100-120 degrees. At this point the lye solutions should be the same temperature, if it is too warm, allow it to cool until within 100-120 degrees.

Slowly add lye solution and give it a quick twirl with the wooden spoon. Mix with stick blender until it thickens, about 5-7 minutes. When the blender is pulled out of the soap and leaves an outline and any drips take a moment to settle in, the soap has reached trace and is finished.

Next, add in essential oils. I used bergamot and sage, one teaspoon of each. Blend with the stick blender one more time to mix in the oils, and pour out the mixture into a container to settle.

I use a rectangular glass tupperware lined with plastic for easy removal. This is not ideal for beautiful soap, but it is a great way of protecting it while it sets. Completely covering the soap will prevent an ash, or white dust, layer from forming.

Once you have poured your soap into a container and (preferably) covered it, place it somewhere where it will not be disturbed for 24 hours. The oven or microwave are great options.

After the soap has settled, remove it from its temporary home and cut it into bars. Wait a week or two to let the soap cure for best results, but if you cannot wait to use it, it is ready.
