Ingredients

  • 1 cup baking soda (sodium bicarbonate)
  • 1/2 cup citric acid
  • 1/2 cup cornstarch
  • 1/2 cup Epsom salt
  • 2 tbsp polysorbate 80 (emulsifier)
  • 3 tbsp coconut oil (melted)
  • 1 tsp water
  • 15-20 drops essential oils (lavender, eucalyptus, or your favorite scent)
  • Natural colorants or cosmetic-grade mica powder (optional)

Equipment

  • Mixing bowls (medium and large sizes)
  • Whisk or spoon for mixing
  • Bath bomb molds (plastic spheres or silicone molds)
  • Measuring cups and spoons
  • Spray bottle with water (for misting)
  • Gloves (optional, to protect hands from dryness)
  • Plastic wrap or parchment paper (for drying)

Instructions

  1. Combine Dry Ingredients: In a large bowl, whisk together the baking soda, citric acid, cornstarch, and Epsom salt until evenly mixed. This creates the fizz base of your bath bombs.
  2. Mix Wet Ingredients: In a separate small bowl, combine the melted coconut oil, polysorbate 80, water, and your chosen essential oils. Add any colorants here if you want vibrant bath bombs.
  3. Slowly Add Wet to Dry: Gradually pour the wet mixture into the dry ingredients, whisking continuously to prevent the mixture from fizzing prematurely. The goal is a damp sand-like consistency that holds shape when pressed.
  4. Mist and Adjust: If the mixture feels too dry, lightly mist with water using your spray bottle, mixing thoroughly after each spray. Be cautious not to add too much water, or the mixture will fizz early.
  5. Fill Your Molds: Firmly pack the mixture into your bath bomb molds, pressing to ensure no air gaps. Overfill slightly and press the halves of the mold together.
  6. Let Set: Allow the bath bombs to dry in the molds for at least 24 hours in a cool, dry place. Avoid humidity which can cause premature fizzing.
  7. Remove and Cure: Gently remove the bath bombs from the molds. For best results, let them cure on parchment paper for an additional 24-48 hours to harden fully.
  8. Store Properly: Keep your bath bombs in an airtight container or wrapped in plastic to preserve their fizz and fragrance until you’re ready to enjoy.

Tips & Variations

“If you want a vibrant, multi-colored bath bomb, try layering different colored mixtures in your molds for a beautiful surprise when fizzing!”

  • Substitute Oils: Try sweet almond or jojoba oil instead of coconut oil for different moisturizing effects.
  • Fragrance Blends: Experiment with blends like lavender and chamomile for relaxation or peppermint and eucalyptus for invigoration.
  • Botanical Additions: Add dried flower petals or herbs inside the molds for a decorative touch, but be mindful of tub staining.
  • Use Silicone Molds: They’re easier to unmold and come in fun shapes for kids or themed gifts.
  • Control Fizz: Adjust the citric acid slightly if you prefer a slower or more intense fizz.
