Sleepytime Magnesium Bath Bombs: Mineral rich bath fizzles infused with chamomile, mandarin, and vanilla.
Magnesium is my new favorite bath ingredient. Whether I’m simply tossing a cup full of Magnesium Flakes into the tub or finishing my bathing ritual off with a quick spritz of Magnesium Body Spray, this amazing mineral is sure to be part of the fun. While bathing with magnesium does not need to be any more complicated than that, the formulator in me just can’t resist experimenting with my favorite things. So it was really just a matter of time before Magnesium Bath Bombs came to life.
This recipe is fairly simple as far as bath bombs and fizzles go. Inspired by magnesium’s fame for aiding restfulness, I decided to combine the Magnesium Oil and Epsom salts with other popular bedtime ingredients. German Chamomile Essential Oil is often used in aromatherapy to promote sleep and relaxation. It also adds a lovely aqua colored tint to the bath bombs which I chose to complement with some mica. The natural color that German Chamomile gives the recipe is gorgeous on its own though. So feel free to omit the mica for a solid colored fizzy.
I just made a small batch for this project, but you can absolutely double or triple this recipe to make more. The basic ratio of baking soda and citric acid is the most important thing to maintain when making bath bombs. The other important thing to keep an eye on is the ratio of essential oil being used. I like to try to keep the total essential oils under 2% for use in bath products. This provides a nice burst of aroma while steering clear of overdosage. Remember that a product’s scent may be much stronger than you realize in the midst of formulation. When it comes to essential oils and fragrance I prefer to take a less is more approach.
Sleepytime Magnesium Bath Bombs
Makes about three 190 gram fizzies
- 1 cup (240 g) Baking Soda
- 1/2 cup (120 g) Citric Acid
- 1/2 cup (175 g) Epsom Salt
- 1 tablespoon (15 ml) Magnesium Chloride Oil
- 1 tablespoon (15 ml) Shea Butter, melted
- 1/2 teaspoon (2.5 ml) German Chamomile Essential Oil
- 1/2 teaspoon (2.5 ml) Mandarin Essential Oil
- 1/2 teaspoon (2.5 ml) Vanilla CO2 Extract
- 1/2 teaspoon (2.5 ml) Two Tone Blue Green Mica, optional
- Combine baking soda, citric acid, and epsom salt in a small food processor and pulse until powders become smooth and uniform. Transfer powders to mixing bowl.
- In a smaller bowl, combine magnesium oil, shea butter, and essential oils. Whisk together, then slowly drizzle liquids into the powder, mixing continuously as you do so.
- Continue to mix the powders together using your hands. Break up any clumps that form and mix until the powder reaches a consistent texture. At this point, the powder should clump together in your hands like snow or damp sand.
- Split the mixture into two parts. Add mica to one bowl and mix until the color is well blended.
- Pack mixture into bath bomb molds. Press each half of the mold firmly, then add another layer of mixture to the tops so that they are overflowing with powder. Press the two halves together firmly until they stick. Gently tap the mold until it releases, then repeat with the other half.
- Place the finished bath fizzies onto a tray and allow them to cure in a cool, dry place for 24 hours. Once they have fully hardened, they should be packaged in an airtight container.
Usage & Packaging
- To use, drop one bath fizzie into warm bath water. The fizzie will bubble and fizz as it dissolves.
- Bath fizzies should be stores in airtight packaging such as cello bags, shrink wrap, or airtight jars.
