How to Make Bath Bombs
By: Madison Ireland
Bath Bombs, you put them in your bath and watch the water become an array of colors. They are very popular at the moment and sometimes very expensive. Here is a way you can make it yourself for much less!
Things you’ll need...
Baking Soda The backbone of this recipe is alkalizing baking soda. It is a necessary complement to the acidic citric acid and part of the fizzing reaction. I order food-grade aluminum free baking soda from here.
Citric Acid The more obscure ingredient in this recipe that a lot of people don’t have on hand is citric acid. It is necessary for the fizzing reaction that makes bath bombs feel like bathing in champagne. I order natural citric acid by the pound from here.
Corn Starch or Arrowroot Corn starch provides the silky feel that we all love from bath bombs. I usually use organic corn starch powder in this recipe. Arrowroot also works but doesn’t provide quite as silky of a finished product.
Salt, Oil and Liquid These are all very versatile and you can pick any combination that you have on hand. You’ll need some kind of: Oil: Pick a simple oil like olive oil, almond oil or coconut oil or get more fancy with sea buckthorn oil, argan oil or apricot oil. Salt: Stick to basic salt or take it up a notch with epsom salt or another favorite salt option. Liquid: Basic water works, but I also love using organic witch hazel for some extra skin soothing.
Scents and Colors This is where the options get endless. Use your favorite essential oils, add dried herbs or make them scent free. You can even add some natural dyes to change the color.
Other Equipment These are easy to make with measuring cups and your hands, but for a fancier and more uniform product, it helps to also have: A digital scale to get the proportions exactly right Molds- For the easiest version, just form these into balls with your hands, but if you are making as gifts or just want fancier shapes, molds are the way to go.

Ingredients… 8 ounces Baking Soda (about 1 cup) 4 ounces Citric Acid (1/2 cup) 1/2 cup (4 ounces) Sea Salt or Epsom Salt 4 ounces Cornstarch (about 3/4 cup) 2 tablespoons oil of choice (this is my personal favorite but any liquid oil will work) 2 teaspoons witch hazel (or water) plus a little more if needed 1 teaspoon vanilla extract (or more water) 30-40 drops of Essential oils or powdered dried herbs (ginger is great) Combine dry ingredients (baking soda, salt, citric acid, and cornstarch) in a large bowl and mix well until combined.
Instructions: In a small bowl, combine the oil, witch hazel and vanilla extract and stir well. Add essential oils if using. Add the liquid ingredients to the dry ingredients a few drops at a time. Mix well with hands (wear gloves if you have sensitive skin). Add powdered dried herbs if using. Mixture should hold together when squeezed without crumbling. You may need to add slightly more witch hazel if it hasn’t achieved this consistency yet. I recommend using a spray bottle with additional liquid to evenly add. Quickly push mixture into molds, greased muffin tins or any other greased container. Press in firmly and leave at least 24 hours (48 is better) or until hardened. It will expand some and this is normal. You can push it down into the mold several times while it is drying to keep it from expanding to much. Using the metal molds will create a stronger and more effective final bath bomb. When dry, remove and store in air tight container or bag. Use within 2 weeks Enjoy!
