Homemade Mermaid Bath Bombs

How many times have you tossed a bath bomb into the tub and enjoyed soaking in it? If you were buying these bath bombs quite often, knowing how to make them is beneficial. You can stop buying them and start preparing them right at home. If you have little kids at home, you can even get them to help you with creating these Homemade Mermaid Bath Bombs using a blend of essential oils, baking soda, and several other ingredients. Once you’ve made them, you can use them daily while bathing, or even wrap them up as gifts for others.

What You’ll Need to Make the Homemade Mermaid Bath Bombs

Make sure you get everything from this essential list to follow the Homemade Mermaid Bath Bombs Recipe to a T. You’re going to need:

Baking Soda. You can get this at the grocery store. The brand of it doesn’t matter.
Citric Acid. Although you can buy it at stores, you’ll save money buying it in bulk on Amazon.
Coconut Oil. You’ll need to melt the coconut oil before using it to create the bath bombs.
Mica Coloring. Add the perfect unicorn-style colors to your bath bombs. You can get these colors on Amazon.
Mermaid Sprinkles. You can look around for mermaid-style sprinkles or use traditional sprinkles in your bath bombs.

These aren’t the only ingredients you’ll need. It’s also important to have a blend of essential oils, rubbing alcohol, SLSA, and cream of tartar. Along with your essential ingredients, it’s also important to have mixing bowls and bath bomb bowls.

What Can I Use If I Don’t Have Coconut Oil?

If you don’t have coconut oil available to use, castor oil works well as a replacement. It’s affordable and easy to find at most drugstores.

Can I Use Different Essential Oils?

You can always use different essential oils. However, if you’re new to using essential oils, it’s a good idea to stick with the recipe. Once you get more experience with combining the oils, you can start adding in different ones to create unique scents for your bath bombs.

How Long Will the Bath Bombs Need to Dry?

Once you’ve used the molds, you’ll need to let your bath bombs dry on parchment paper for at least 10-12 hours before touching them. If you mess around with them while they’re still wet, they’ll easily fall apart. Once they’re dry, you can wrap them or store them in a container and use them as often as you’d like while bathing.

Can I Add a Surprise in the Center?

You can add a surprise in the center while following this Homemade Mermaid Bath Bombs Recipe. You would need to place the surprise in the middle of your bombs before attaching both shells to one another to create the circle shape. Some people like to add small toys or fashion jewelry to their bath bombs.

What's needed:

1 cup baking soda

1/2 cup SLSA (Sodium Laurel Sulfoacetate)

1/4 cup cream of tartar

1/2 cup citric acid

2 tablespoons melted coconut oil

10-20 drops of each of the following

Orange essential oil
Grapefruit essential oil
Lime essential oil
Tangerine essential oil

Pink, purple and blue, or teal mica coloring

2 tablespoons rubbing alcohol

Mermaid inspired sprinkles (optional)

Spray bottle of rubbing alcohol

1 large mixing bowl

3 smaller mixing bowls

Bath bomb molds or silicone molds

How to make Mermaid Bath Bombs

In a large mixing bowl, add baking soda, citric acid, SLSA, and cream of tartar.

Using a sifter or your hands, break down any lumps in the dry mixture. Mix dry ingredients together with your hands or a whisk.

Add orange, tangerine, lime, and grapefruit essential oils to a small bowl

Next, Add the coconut oil and rubbing alcohol and mix together. Slowly add the liquid ingredients to the dry ingredients. Add about 1 tablespoon at a time, whisk together well and repeat until liquid mixture is incorporated into the dry mixture. You will know when the mixture is perfect when it feels like wet sand and you can press the mixture together in your hands and it stays together (see photos Step 16) Separate the mixture evenly into three bowls.

Add your blue-colored mica powder or soap coloring to one bowl. Blend with your hands.

Repeat for the purple and pink colors.

Take a bath bomb mold or your silicone mold and add just a small bit of the mermaid sprinkles (optional) and layer the three colors. Press down gently. Repeat on the other side.

Press the mold together tightly. You may need to make a slight twisting motion to get all the excess mixture. **Please note** You may need to use your spray bottle of rubbing alcohol to spritz your mixture if it gets too dry. Give a few spritzes and mix together until it has that wet sand feel again.

Gently tap on the top of one side of the mold and release the mold from the bath bomb. Turn the mold over in your hand and repeat. Carefully set the bath bomb on parchment paper and allow it to dry overnight. The next day, the bath bomb should be hard and ready to go! Store in an airtight container until ready to use. Drop one in the bath when ready to use! This Mermaid Bath Bomb smells AMAZING!!!
