The Perfect Bath Bomb Recipe for your DIY Bath Bomb

A bath bomb recipe with natural ingredients!

Pure Henry Opinion

I love a bath bomb, and using this bath bomb recipe and making them at home lets you avoid the chemical additives that are put in some store bought varieties.  Bath bombs never get old to me.  I love the scent.  I love the fizz, and I love the relaxing feeling I get after soaking in the bath.  This bath bomb recipe is easy to make and the ingredients can provide a lot of positive rewards for your body. I prefer to use the top quality organic and non-GMO ingredients when making my bath bombs.  The two ingredients that create the fun are the baking soda and citric acid.  This is where the fizz comes from.  Not all bath bombs contain corn starch, but this bath bomb recipe does, and I prefer it as an ingredient.  It makes the bath bomb have a smoother consistency.   Also, included in this bath bomb recipe are epsom salts, and essential oils for a beautiful scent.  

You can create any scent you want by using essential oils.  Essential oils provide wonderful therapeutic benefits and aroma.  Some of my favorite essential oil combinations are below.

Our bath bomb recipe contains a few very beneficial ingredients.  Epsoms salts, aka magnesium sulfate, provide many healing benefits for the body through skin absorption by soaking in the bath.(1) Epsom salt has been shown to increase circulation and provide healing benefits to your skin aiding in healing any cuts or scrapes you might have.(2)  It is not only good for your skin but it is beneficial for your mind, too, helping to protect against anxiety. (3) The baking soda in the bath bomb recipe is antibacterial and helps eliminate oder.(4)  To further add benefits to our bath bomb we love using calendula oil for its antimicrobial properties and inflammation reduction properties.  



  • 1/2 Cup Banking Soda
  • 1/4 Cup Epsom salts
  • 1/4 Cup Corn starch
  • 1/4 Cup Citric Acid
  • 1 Tablespoon of Caster Oil (you can really use any oil)
  • 2 Teaspoons of essential oil your preference
  • 1-2 teaspoons of water
  • Food coloring to your preference

Mix all the dry ingredients thoroughly.  Mix all the wet ingredients thoroughly, including the food coloring.  I like to shake it up in a small container so the wet ingredients are evenly distributed when I drip it slowly into the dry ingredients.  Slowly, drip the liquid mixture into the dry ingredients and quickly stir, so the mixture doesn't react.  Stir the ingredients until it appears like moist sand, and color is evenly distributed.  

To mold the bath bombs, I like to use metal molds the best.  Firmly pack the mixture into both sides of the mold and press the two halves together.  I like to place a rubber band on the outside of the mold to hold it together tightly.  Let it sit for 10 minutes and remove it from the mold.  You want the bath bomb to be firm enough to dry on its own without losing shape.  If you let it dry in the mold it will sometimes get stuck in the mold.  If you want to let it dry in the mold longer make sure you coat the mold with coconut oil before filling it.  This will help the removal from the mold.
