Yield: 6 Bath Bombs

Materials

  • 1 cup baking soda
  • 1/2 cup citric acid
  • 1/2 cup Epsom salts
  • 2-3 tablespoons baby oil
  • A few drops of arnica oil optional
  • Essential oils of your choice
  • Dried rose petals or any other dried flowers

Instructions

  • Mix the Dry Ingredients: In a large bowl, combine the baking soda, citric acid, and Epsom salts. Whisk together until well mixed.
  • Mix Wet Ingredients In a separate bowl: Mix in the baby oil and arnica oil. 10-15 drops of your chosen essential oils A few drops of food coloring if you want to add color to your bath bombs
  • Combine Wet and Dry Ingredients
    Gradually add the wet ingredients to the dry ingredients, mixing constantly. This step requires some patience as you don't want the mixture to fizz. A whisk or your hands (wear gloves if you have sensitive skin) work well for this.
  • Incorporate Flowers: Add the dried rose petals to the mixture.
  • Mold the Bath Bombs: Once the mixture starts to hold together when squeezed, it's ready to be molded. You can use a variety of molds, including
    Special bath bomb molds
    Muffin tinsSilicone molds
    Silicone molds
    Or we used small glass cups/ sauce cups
    Pack the mixture tightly into your chosen mold. If you’re using round bath bomb molds, make sure to overfill each half slightly before pressing them together firmly.
  • Gently tap the molds to release the bath bombs and then allow the bath bombs to sit for 12-24 hours before carefully removing from the molds.

Notes

Can I use different oils in my bath bombs? Yes, you can substitute the baby oil with other carrier oils such as coconut oil, almond oil, or jojoba oil. Just ensure they are skin-safe and moisturizing.
How can I make my bath bombs more colourful? To add a splash of colour, you can use food-grade dyes or mica powders. Add them to the dry ingredients before mixing in the oils.
Why are my bath bombs crumbling? If your bath bombs are too dry and crumbly, try adding a bit more oil to the mixture or lightly spritzing it with witch hazel. The mixture should hold together when pressed into a ball.
Can I use fresh flowers instead of dried ones? It's best to use dried flowers as fresh flowers contain moisture, which can cause the bath bombs to fizz prematurely or mold over time.
