Cream of Tartar Bath Bombs without Citric Acid
No need to go hunting for citric acid—these aromatherapy bath bombs are made with an ingredient you can find at any grocery store.
Yield: 4 bath bombs
Cost: $10
Equipment
- Mixing bowls
- Bath bomb molds
Materials
- ½ cup baking soda
- ¼ cup corn starch
- ¼ cup cream of tartar
- ¼ cup Epsom salt
- 1 teaspoon water
- 1 teaspoon essential oil
- 1-¼ teaspoon coconut oil
Instructions
- Combine the dry ingredients in a small bowl and whisk to remove any clumps.
- In a separate bowl, combine the wet ingredients (make sure the coconut oil is completely melted first).
- Slowly pour the liquid mixture into the dry mixture, whisking as you go. The dry ingredients might fizz a little as you pour. If this happens, try adding the wet ingredients more slowly. It should stick together fairly well in one or two big chunks. If it's still too powdery to hold together, try adding a tiny bit more water.
- Spoon the mixture into your molds and press firmly. Let dry for a few hours, or better yet overnight, before removing from the molds.
Notes
I used mini muffin liners for molds the second time I made these. Because they turned out small, you may want to add 2–3 bath bombs to each bath. If you make standard-size bath bombs, one bomb per bath should be enough.
Store bath bombs tightly wrapped in plastic wrap (or an airtight container) in the refrigerator for up to 4 weeks.
