Learn how to make the best Charcoal Bath Bombs in this easy DIY beauty tutorial.
I prefer to go light on the charcoal powder because it can leave behind a residue that needs to be cleaned (try this tub cleaner). You can add extra charcoal powder to the dry ingredients for totally black bath bombs.
As far as essential oils go, I used lavender and Roman chamomile, but you can choose any scent combination you like. If you prefer bath salts over bath bombs, try our DIY Charcoal Bath Soak.
How to Make Charcoal Bath Bombs
- Dash activated charcoal powder
- Dusting mica powder
- 1 cup baking soda
- ¼ cup citric acid
- 8 drops lavender essential oil
- 4 drops Roman Chamomile essential oil
- 1-2 tablespoons filtered water
- Bath bomb molds
- Mixing bowls
- Start by adding a dusting of activated charcoal and mica to the bottom of each cavity of the silicone mold – a little goes a long way.
- Combine the baking soda and citric acid in a small mixing bowl, then add the essential oils.
- Using your hands or a small spatula, add in just a little water at a time and mix. You’ll be able to feel the consistency go from a grainy powder to a wet smooth sand consistency that will hold its shape when you press it together.Quickly press the mixture into the molds, making sure to push all the way down on each one so the finished fizzies will hold their shape.
- Allow your soothing bath fizzies to dry for 12-24 hours. The amount of time it takes will simply depend on the humidity and size of the molds. The bath fizzies are ready when they feel hard, dry and maybe a little brittle to the touch. They should pop right out of the molds. Store them in an air tight container until ready to use.
How to Use
- Draw a warm to hot bath and add 2-4 charcoal bath bombs, depending on the size of you tub. Soak for about 20 minutes.
