Bath Bomb Recipe in Video

Dry Ingredients:
  • 3 Cups of Baking Soda
  • 1 ½ Cups of Citric Acid
  • 1 ½ Cups of Corn Starch or Arrowroot Flour (I used Corn Starch)
  • ½ Cups of Epsom Salts
Wet Ingredients:
  • .25 oz. Distilled Water
  • .50 oz. of 91% Rubbing Alcohol or Clear Alcohol (I used Clear Alcohol)
  • 2 Tablespoons of Fragrance Oil
  • 2 oz. Grapeseed Oil or Sweet Almond Oil or Light Oil of Choice (I used Sweet Almond Oil)
  • Colorant to be Added to Wet Ingredients
  • 1/4 to 1/8 Teaspoons of Mica or LaBomb Colorant, Lake Colors or Food Coloring


  1. Weigh and measure your Dry Ingredients (Except Epsom Salts) and whisk/gently stir. (Please use a Face Mask)
  2. Weigh and measure your Wet Ingredients.
  3. Add your Colorant to your Wet Ingredients. Mix your Wet Ingredients with your Epsom Salts. Then slowly add the Epsom Salts Mixture into your Dry Ingredients.
  4. That’s it. You are done!

Do NOT add additional wet ingredients. Mixture may feel dry at the end, but try NOT to add additional liquids as this may cause “warts” on your Bath Bombs.

Let Bath Bombs “dry out” in a dry location, preferably away from humid areas. I prefer a closet or the oven.

    I converted the wet ingredients into teaspoons/tablespoons because I don’t have a scale that measures in ounces. The mix was very dry and I kept adding water, witchhazel interchangeably even more oil, couldn’t get it wet enough. Instead of adding Epsom salt I added kaolin clay and I also added 3T of powdered milk. I also added poly80. My mixture wouldn’t hold in the ss mold. After 3 hours of adding liquid, remixing, remolding, I just gave up. I put some in silicone molds. We’ll see how they pan out tmrw. Overall this was awful and it was such a large batch…FAIL 😣
