I absolutely love relaxing in a bath and using bath bombs is one of my favorite parts of the ritual. The smell, the fizz, the soft skin. What isn’t to like? Well, not the price. They definitely get expensive—one of them can be around $6 bucks at Lush.
I’ve always wanted to make my own bath bombs but only recently started getting into it. Getting all the supplies might seem expensive at first since you’re buying them at once, but making your own is ultimately very cost effective. Plus, you can reuse the supplies for other projects. I’ve been making bath melts, lip balms, lip scrubs, and hand scrubs as gifts and for myself.
This recipe will make about 3 large bombs. You can put colorants in if you want, but I like to keep it as natural as possible.
You Will Need
2 cups of baking soda
1 cup of citric acid
1/2 cup of Epsom salt
1 tsp jojoba oil
2 tbs castor oil or olive oil
2 tbs of shea butter (this is totally optional)
20 drops of your choice essential oil (I’m using bergamot and sweet orange in the photos)
Water in a spray bottle (one that has an ultra fine mist is best)
Note on citric acid: I get mine from Amazon. Citric acid makes the fizziest bath bombs. I’ve seen substitutes online (like cream of tartar, for example) but I’ve never gotten as good of results.
1. In a large bowl combine the oils and essential oils. Add the Epsom salt and mix it thoroughly.
3. Use your hands to start kneading the dry mixtures into the oils. Do it slowly so the ingredients don’t puff up everywhere.
5. Now, you’ll need to start adding little sprays of water into the mixture, only enough so that it clumps together and can be molded. This is a very slow process, but do not rush it! The second you add too much water the citric acid will bubble and that will be it for the bath bombs.
6. Spray, knead, spray, knead. Eventually the mixture will become just damp enough to stay clumped together. To make sure it is ready, pack everything into your mold and release it. If it doesn’t crumble then it’s ready.
7. Tightly pack your mixture into a mold. I don’t have a mold specifically for bombs, so I just use a measuring cup. Gently flip the mold out to release. Set it on a wire cooling rack and let it sit for a few days undisturbed.
8. Be aware that the bombs might be slightly sticky to the touch at first, but eventually they will dry out. If I’m giving them as a gift, I wrap them in wax paper and twist the ends like it is a big candy. If you’re going to use them for yourself, store them in a plastic container or ziploc bag otherwise.
Note: The oils in the bomb might make the tub a little slick afterwards, so leave a little note for your recipient if you’re giving them as a gift.
