FAQs
What makes bath bombs fizz?
The reaction between baking soda and citric acid creates the signature fizz when added to water.
Can I substitute essential oils?
Yes, you can use any skin-safe essential oil or fragrance oil you prefer.
Why are my bath bombs cracking?
Too much or too little moisture can cause cracking. Add liquid slowly and test texture as you mix.
Can I use water instead of witch hazel?
Yes, though witch hazel evaporates more quickly and reduces the risk of premature fizzing.
Are bath bombs safe for sensitive skin?
Yes, but patch test first if you’re sensitive to essential oils or fragrances.
Can I make these without a mold?
Yes, you can shape the mixture by hand or use silicone molds, muffin tins, or cookie cutters.
How long do bath bombs need to dry?
At least 24 hours at room temperature. Ensure they are fully dry before storing.
Will these leave residue in the tub?
Minimal residue may occur due to the oils and botanicals. Rinse the tub after use to keep it clean.
Can I use these in a hot tub or jacuzzi?
It’s best to avoid using bath bombs in jets or hot tubs, as oils and particles may clog filters.
Are these safe for kids?
Yes, with gentle ingredients and under adult supervision, they’re great for children’s baths.
