Yesterday in the first part of this blog post, we talked about the different types of CBD, the legality of its use, and the potential usage rates of CBD in bath bombs. But today I want to show you how to actually incorporate this ingredient into your formulation so you can make awesome bath bombs like these! At the end of this post we also have a special, limited time offer from Kayla Fioravanti, co-founder of Ology Essentials (our favorite CBD Supplier!) as well, so make sure you don’t miss out!

Now first and foremost, I suggest using a very simple recipe to make your CBD bath bombs. Since the isolate itself is an expensive additive, a simple recipe will help cut down on the COGS (the cost of goods sold/ingredient cost). Also, I’ve found that with CBD bath bombs it helps to soak for at least 20 minutes. That means it’s better if the bath bomb fizzes out fast and distributes the isolate into the bath water as quickly as possible. Our free basic recipe is a great place to start! 

If you’ve never made bath bombs before, or if you’ve made them with disastrous outcomes, this recipe is super easy to work with and has consistently great results! Before you use an expensive ingredient like CBD we suggest that you give basic bath bombs a shot first, but if you’re ready to take the leap, then let me show you how I made these CBD bath bombs!

No matter what kind of CDB you choose, it’s easy to incorporate it into your bath bombs. You can mix by hand or use a stand mixer with the paddle attachment! I’m going to use 1 gram of Hemp CBD Isolate from Ology!

• Combine your dry ingredients (except your citric acid)

• Weigh out your oil. We like avocado oil, but you can use any oil of your choice, including solid oils like coconut, or hard butters like cocoa butter. 

• Gently heat your oils. If using solid oil and/or butter make sure to fully melt them.

• Add your CBD to your warm oils and stir. If using crystal/powder isolate, make sure to stir until dissolved. You may need to gently reheat the oil until the isolate is fully incorporated. 

• Once dissolved, add your fragrance and/or essential oils to the oil blend and stir

•Add to your oil blend to your powder ingredients and thoroughly mix

•If adding color, I typically add it at this point, before I add my citric acid.

•Add citric acid and thoroughly mix

•Add binder and mix well! You can use witch hazel, 91% isopropyl (rubbing) alcohol, or–my favorite–distilled water! We suggest adding binder with a spray bottle. For a batch this size I generally use 2-3 sprays of water which equals approximately 3-4 grams of water! 

Your mix is ready when it can pass a drop test. Simply squeeze a small handful of the mix and drop it back into the bowl from a few inches up. If the clump cracks, you might need to mix a little longer, add a tiny bit more oil, or give it one or two more sprays of binder (always add more binder LAST since a little goes a long way!)

Mold your bath bombs using your favorite bath bomb mold. I usually use 3D printed molds, but this one from WyldeThymeStudios on Etsy seemed perfect for the project and was super easy to work with. Not all bath bomb molds are as easy as others though, so make sure you have a back up mold just in case the one you choose gives you trouble.

To use a vacuum form mold, sprinkle some mix in, tap in the details with your fingers, then fill the mold the rest of the way, packing it with the palm of your hand. With molds like these, make sure you scrape the back flat and pack the edges extra tight! That will help prevent them cracking when they are drying.

To unmold, pull the edges of the vacuum form mold away from the bath bomb then flip onto a pan or tray. Massage the top and sides of the mold to help it release. Finally, tug the sides away from the bath bomb as you pull up. 

For best results, allow your bath bombs to dry for a minimum of 24 hours–although 72 hours is preferred–before testing or packaging.

Make sure you calculate how much CBD is in each bath bomb. If you have left over mix you can subtract it from your total, or you may have to calculate how much CBD is in each ounce and list your bath bombs as such. This is another great reason to have your recipe converted to weight instead of being volumetric and you can read about that here.
