How To Make A Bath Bomb Without Citric Acid?

Bath bombs are skin soothing items that nourish and soothe your skin. They are a great way to enhance your bath, as bathing with them feels like you are bathing in a painting.

Bath bombs are hard-pressed blends of dry ingredients, which fizz when wet. Usual bath bombs contain a special fizzing ingredient called citric acid, that creates the fun fizzy reaction, when introduced to water. However, the presence of citric acid may not suit everybody’s skin. The good news is that you can make bath bombs at home with the ingredients found at the grocery store and you can omit the use of citric acid.   

In this post, we will provide you with the recipe of how to make a bath bomb without citric acid.

Let’s get started.

Ingredients

Sodium bicarbonate (baking soda) and citric acid are the two primary components in bath bombs. Their combination creates a fuzzy reaction, when the bath bomb is immersed in the water. If you don’t have any citric acid or don’t want to use this component, you can instead use the ‘cream of tartar.’

Ingredients you should take include:

  • 2 cups baking soda
  • 1 cup cream of tartar
  • 1/2 cup cornstarch
  • 120 gram salt (6 tablespoons) – non-iodized table salt, sea salt, or Epson salts
  • 2 teaspoons essential oil (lavender, chamomile, peppermint, rose, bergamot, sandalwood, jasmine, tea tree, rosemary, orange, or lemon)
  • 1 tablespoon oil (olive oil, coconut oil, sweet almond oil, or vegetable oil) – optional
  • Food coloring – entirely optional
  • Dried flower buds or petals of your choice (rose, lavender, etc.) – optional
Another option for bathbomb without citric acid is lemon juice, because its main component is actually a citric acid. However, lemon juice does contain other ingredients besides citric acid, like water. The citric acid you get from lemon juice is relatively weak and diluted because of the water, but it’s still there. Even though these bath bombs won’t fizz as enthusiastically as their citric acid counterparts, they will do the job.

Supplies

  • Large bowls for mixing dry ingredients 
  • Small bowls for mixing wet ingredients
  • Metal fork or whisk
  • Tap water
  • Mold – any shape would work

Step 1: Mix the dry ingredients into a large bowl

Take a large bowl and mix the following ingredients:

  1. 2 cups baking soda
  2. 1 cup cream of tartar
  3. 1/2 cup cornstarch
  4. 120 gram salt
  5. Dried flower buds or petals

Now, using a metal fork or whisk, thoroughly mix the ingredients until the mixture is proportionate. Hold the dried flower petals or buds until you mix the powdered ingredients. Flower buds are optional, and you can add them if you want. You need to ensure that there are no lumps formed. The mixture needs to be completely dry.   

Step 2: Mix the wet ingredients into a small bowl

Take a small bowl and mix the following ingredients:

  1. 2 teaspoons essential oil
  2. 1 tablespoon oil of your choice (any type of skin care oil)
  3. Food coloring – 2-3 drops
Please Note: The quantities mentioned can be altered in the case of wet ingredients. It will depend on what you want. When you combine the wet ingredients into the dry ingredients, the color and the essence of oils will diminish. So, use the quantities as per the requirements.

Take a small bowl and start mixing the ingredients one by one. Use a metal fork to properly blend all the components, until they form a single unique mixture. You need to be cautious when adding the essential oils as too much can make you feel nauseated.

Step 3: Combine the large bowl mixture with small bowl mixture

Take a spoon and gradually pour the wet mixture into the dry mixture, while stirring continuously. If you pour the wet mixture in all at once, it will fizz.

In case the final mixture is so dry that it won’t hold and you can’t squeeze it into a shape, then spray it with a bit of water and mix thoroughly with a fork.

You can determine the moisture content in the mixture by squeezing a small amount in your hand. If the mixture compresses together without separating, you can put it in a mold. However, if it starts crumbling apart, when you squeeze the mixture together, spray water until it easily compresses into a ball.

Step 4: Press the final mixture into a bath bomb mold

Pack the final mixture tightly into the bath bomb molds you prefer. You can choose from silicone, plastic, aluminum or stainless steel molds. If you are making in large quantities, silicone molds are preferred. However, given their very nature of bending and twisting, only professionals are advised to use silicone molds. If you are a beginner getting started with bath bomb making, you can use stainless steel molds. Stainless steel molds have a smooth polished surface that allows you to remove the end-product with ease.

Pro Tip: before filling in the molds with the mixture, you can sprinkle dried flower petals, dried rosebuds, orange peels, or springs of rosemary to give your bath bombs a flowery, decorative top.

Step 5: Allow the mixture to dry in the mold

Leave the mixture in the mold undisturbed for at least 24 hours. Do not place the molds under direct sunlight in hope of getting the mixture quickly dried. Allow it dry under normal room temperature. You can check if the mixture is completely dried by touching the surface and see if there is any dampness.

Step 6: Carefully remove the final product from the molds

This is the trickiest part of the whole bath bomb making. You need to carefully remove the bath bombs from the molds without damaging their surface and edges. Once you carefully remove them from the molds, allow them to air dry for another 24 hours.

That’s it, your bath bombs without citric acid are ready. Drop one in your bath and enjoy the fizz and aroma!  

Conclusion

Following the above-mentioned steps will help you in making a real fizzing bath bomb without citric acid.
