Ingredients in this DIY Bath Bomb Recipe

Before we get to the recipe, I want to share about some of the benefits of each of these bath bomb ingredients:

Baking Soda and Citric Acid

The main ingredients of a bath bomb are baking soda and citric acid. They are the ones that cause the fizzy reaction when they come into contact with water for the chemical reaction.

Citric acid is a weak organic acid that reacts with baking soda (sodium bicarbonate), which is a base, to produce carbon dioxide gas. This reaction generates the effervescent fizzing and bubbling that makes bath bombs so enjoyable.

Beyond the fizzing reaction, citric acid also contributes to the acidity of the bath water, which can help to soften the skin and promote exfoliation. It can act as a preservative, helping to prolong the shelf life of the bath bomb as well.

Baking soda, on the other hand, not only reacts with citric acid to produce carbon dioxide gas, but it also helps to soften the bath water. It can leave the skin feeling smoother and more moisturized after bathing.

Baking soda is also one of the main ingredients for a detox bath too.

Epsom Salt

Epsom salt, also known as magnesium sulfate, serves several purposes in bath bombs.

First off, it can help to soothe sore muscles and joints when dissolved in warm water, making the bath experience more relaxing and therapeutic.

Epsom salt also contributes to the fizzing reaction of the bath bomb when it comes into contact with water, adding to the sensory experience of using the bath bomb.

Epsom salt can also help to detoxify the body and improve skin health too!

Pink Kaolin Clay

The pink kaolin clay is what gives it this beautiful pink color. You won’t need any food coloring or mica powder, which is really important to me.

I hate cleaning the bath after the colors! Plus, some coloring is hard for sensitive skin, so thankfully with this bath bomb mixture, you won’t have to worry about that!

Kaolin clay is also known for its gentle cleansing properties. When added to bath bombs, it can help to draw out impurities and excess oils from the skin, leaving it feeling clean and refreshed.

Pink kaolin clay is often considered one of the mildest clay varieties, making it suitable for sensitive or irritated skin. It can help to soothe inflammation and calm redness, making it a great choice for those with sensitive skin.

Sweet Almond Oil

Sweet almond oil is rich in fatty acids and vitamins, making it an excellent moisturizer for the skin. It helps to hydrate and soften the skin, leaving it feeling smooth and nourished after bathing.

Almond oil can also act as a binding agent in homemade bath bomb recipes, helping to hold the other ingredients together and create a cohesive mixture that forms a solid bath bomb.

You can use any carrier oils you prefer. If you only have olive oil or melted coconut oil, that’s fine too!

Essential Oils

Some of my favorite essential oils for a warm bath depends on what I want to accomplish with the bath.

For sore muscles, I like to add in eucalyptus, peppermint, copaiba, or a muscle blend.

If you had a long day and just want to relax, you can enjoy lavender essential oil for a nice warm bath.

One of the best things about making natural bath bombs is that you can use different scents to make your hot bath just what you need!

I don’t use fragrance oils, since they are full of chemicals and can cause a lot of skin irritations.

Natural Bath Bomb Recipe without Corn Starch

Now you know about the essential ingredients in this simple bath bomb recipe, here is how to make your own.

If you use this recipe, it will make 3 small and 2 medium bath bombs.

Supplies

½ cup baking soda
¼ cup citric acid
¼ cup Epsom salt
3 tablespoons Pink Kaolin Clay
1 tablespoon sweet almond oil
½ tablespoon water
Bath bomb molds

Directions

Add the baking soda, citric acid, Epsom salt, and kaolin clay to a large bowl, and stir with a whisk until all of the dry ingredients are completely combined.

Mix the sweet almond oil and water together. The wet ingredients mix easily if you shake it in a small glass jar.

Slowly pour a tiny bit of liquid into the mixture while whisking.

You want to do this drop by drop so you don’t make the bath bombs fizz, otherwise you may ruin the mixture. Whisk together until you have a mixture that easily clumps together like wet sand.

Overfill two halves of the bath bombs mold, press together, and give a quick twist.

Allow the mixture to set in the mold for 1 hour, then you can unmold and allow to set overnight to completely harden.

Notes

You can use any carrier oil you prefer. Jojoba, hemp seed, avocado, are all great options.
If you are using essential oils, add in with the wet ingredients.
Any clay should work, but I only used Kaolin clay for this recipe. You would have to try it out just to double check!
Many like to use silicone molds, but I prefer metal molds for bath bombs. The silicone molds are great for soaps, but they do make it harder to keep the shape of the bath bomb.
