Total Time 45 minutes


  • 2 cups baking soda
  • 1 cup citric acid
  • 1/2 cup cornstarch
  • 1/4 cup Epsom salts
  • 1/4 cup SLSA
  • 1/2 cup dried lavender
  • 1/3 cup coconut oil
  • 1 tbsp polysorbate 80
  • 10 drops Chamomile, Rosemary, Frankincense, Ginger, Lavender and Marjoram essential oils
  • 1/2 tsp mica powder we used purple and teal


  1. In a large bowl add the baking soda, citric acid, cornstarch, SLSA, epsom salts and the dried lavender. Stir gently. Citric acid can irritate the sinuses if it is inhaled.

  2. In a small microwave safe container melt the coconut oil until it is liquid. Add the essential oils and polysorbate 80. Blend together. Feel free to adjust the essential oils to meet your preferences. I also find citrus works very well on headaches even though we didn't use it in this batch. But also, just lavender by itself is amazing at helping to relieve our headaches. 

  3. Add the wet ingredients to the large bowl with the dry ingredients and mix together well. I recommend putting on some gloves and using your hands to really mix it all in. You want it to stick together like wet sand. If the air in your home is particularly dry you may need to add more coconut oil. Add only a teaspoon at a time and blend in really well until you reach the desired consistency. 

  4. Divide your mix in two bowls. Add 1/2 teaspoon of purple mica powder to one and teal to the other one. Mix well. If you want your bath bombs darker in colour, you can add more mica powder. But too much mica will create a mess in the tub. A little goes a LONG way. 

  5. Loosely mound the bath bomb mixture into both halves of the bath bomb mold. To get the layered look simply add a bit of purple, then a bit of teal, then a bit of purple. Once you have them nicely heaped up, bring the halves together and twist until the edges touch and all excess falls back into the bowl. Gently tap the ends of the mold, then carefully pop the bath bomb out of the mold. 

  6. Set it somewhere warm and dry, and allow it to set overnight.
