Bath Bomb Recipes and Tutorials

It’s a good idea to have a bath bomb recipe you want to use before you begin shopping around for citric acid, so that you know how much you need to purchase. Most recipes call for about 4 ounces of citric acid to make 3-4 small bath bombs. Although you may already have a bath bomb recipe in mind, here are a few more for you to check out:

What Is Citric Acid?

Citric acid is a weak organic acid that occurs naturally in citrus fruit. It has many uses including as a preservative, a sour flavoring, an emulsifying agent, and as an additive in processed food. It’s such an effective preservative that it’s found in many canned food as a preventative against botulism. Although it can be derived from lemon or pineapple juice, modern citric acid is often made from Aspergillus niger – common black mold – because it is a cheap, safe, and effective process.

Citric acid comes in either anhydrous (dry) or monohydrate (liquid) form. For bath bombs, you’ll need to find dry citric acid. Most citric acid available for purchase is in a powder or fine granular form, so finding citric acid suitable for homemade bath bombs shouldn’t be a problem.

Why Is Citric Acid an Important Bath Bomb Ingredient?

The fizzing effect of bath bombs is one of their biggest appeals. The fizziness happens when two key ingredients, baking soda and citric acid, react to the water. This reaction causes the release of carbon dioxide gas and makes bubbles erupt as the bath bomb dissolves. Although citric acid substitutes like cream of tartar or lemon juice can be used, citric acid gives your bath bombs a more impressive fizz.

Citric Acid Safety

Although an acid, citric acid is fairly mild and generally safe to use. However, repeated consumption may cause the erosion of tooth enamel. Exposure to pure citric acid is also dangerous. Inhalation of the dust from the powder can cause shortness of breath, cough, and sore throat. Ingesting large quantities can cause abdominal pain and sore throat.

When purchasing citric acid, always be sure to buy food grade or non-food grade that is marked safe for external use.

Other Uses For Citric Acid

It is often cheaper to buy citric acid in bulk quantities, but this means having a lot of excess after you’re done making your bath bombs. Don’t worry about having leftover citric acid, because it has many uses ranging from an additive in homemade canned foods to descaling hard water buildup around your home. Some common uses for citric acid:
