Easy Bath Bomb Recipe (Beginner Formula)

Ingredients:

  • 1 cup baking soda

  • ½ cup citric acid

  • ½ cup Epsom salt

  • ½ cup cornstarch

  • 2–3 teaspoons water

  • 2 teaspoons essential oil

  • 2½ teaspoons coconut oil (melted)

  • Optional: natural colorant or mica powder

👉 This ratio is critical — it ensures the perfect fizz without premature activation.

Equipment You’ll Need

  • Mixing bowls

  • Whisk

  • Spray bottle

  • Bath bomb molds (or tightly packed measuring cups)

That’s it — no fancy tools required.

Step-by-Step Instructions

Step 1: Combine Dry Ingredients

In a large bowl, whisk together:

  • Baking soda

  • Citric acid

  • Epsom salt

  • Cornstarch

Remove all clumps for a smooth finish.

Step 2: Mix Wet Ingredients

In a separate container, combine:

  • Melted coconut oil

  • Essential oils

  • Water

Slowly is the secret here.

Step 3: Combine Without Triggering the Fizz

Gradually drizzle the wet mixture into the dry ingredients while whisking constantly.

Avoid pouring too fast — moisture activates the fizz reaction.

Your mixture should feel like slightly damp sand.

👉 If it holds shape when squeezed, you nailed it.

Step 4: Add Color (Optional)

Start small — a little pigment goes a long way.

Too much coloring can stain tubs.

Step 5: Mold the Bath Bombs

Pack the mixture tightly into molds.

Press firmly.

Then gently remove.

Step 6: Let Them Dry

Allow bath bombs to dry for 24 hours in a low-humidity space.

Patience here prevents cracking.
