Ingredients

Instructions

  • In a large mixing bowl, thoroughly combine the baking soda, cream of tartar (or kaolin clay), SLSA. Stir in mica colorant if desired until completely combined.
  • In a small container, combine the oil, fragrance/essential oil, and Polysorbate 80 (if using).
  • Stirring constantly, slowly mix the liquids into the dry ingredients until they are completely combined.
  • Add citric acid to the mixture and stir until it is fully incorporated.
  • Test to see if the mixture is a moldable consistency - it should feel like slightly damp sand and hold together when squeezed in your hand.
    If the mixture is not quite wet enough to mold, spritz two to three times with a spray bottle of witch hazel and mix well. Repeat as necessary until the proper consistency is reached.
  • Fill both halves of the bath bomb mold with the bath bomb mixture, making sure to overfill both sides of the mold just a bit. Press both halves of the mold firmly together.
  • Carefully release the bath bomb from the mold (tap the mold lightly with a wooden spoon if needed) and allow it to dry completely for 24-48 hours depending on the temperature and humidity of your location.

Notes

The amount of fragrance oil and/or essential oil that will need to be added to your bath bomb mixture will vary widely depending on what you are using. Generally, fragrance oil can be added by the 1/2 teaspoon until the desired amount of fragrance is reached. Essential oils are often far more potent than fragrance oil, so we recommend adding 15-20 drops of essential oil to each recipe to start and then adding more in 5 drop increments until the desired level of fragrance is achieved.
