Let’s Make Hidden Color Bath Bombs

I recently purchased an 8-piece bath bomb set featuring a variety of heavy duty bath bomb molds. It included two differently sized sets of round molds, a leaf and a tulips shaped mold, and a pineapple bath bomb mold. Ever since I shared a guest recipe on how to make rainbow bar bath bomb embeds for hidden color bath bombs, I’ve been wanting to try it myself. Unfortunately, bath bombs are not my strong suit. Not to mention the humidity in Southwestern Virginia right now has been insane. (We seriously have been getting more rainfall than Seattle, Washington the past few years.)

Formulating A No Fail Bath Bomb Recipe

When I received my new bath bomb molds, however, I knew it was time to just give it a go. Rather than attempt a two part process where I first make embeds and then make the bath bombs to hide them in, I thought I’d try it as a one step process with a single hidden color inside. I ended up using a blue lake dye (made specifically for bath bombs) for the hidden color. I then used a small amount of mica in conjunction with polysorbate 80 (so there’s no staining or colored bath tub ring) for the surrounding colors. This pretty much makes this bath bomb project for people – like myself – who struggle with practicing patience.

In addition, I formulated these pineapple hidden color bath bombs order to ensure a no fail bath bomb recipe even in humidity. (No joke, I made these during the day with the humidity at 43% because I was tired of putting them off. I then unmolded them the next day with the humidity at 84%.) To achieve this I included moisturizing shea butter and babassu oil – a rockin’ substitute for coconut oil – along with a bit of cream of tartar.

Finally, I also added magnesium flakes for their natural skin care benefits. Also known as magnesium chloride, magnesium flakes are better suited than Epsom salt for topical application. When used in bathwater, magnesium flakes are a great natural remedy for stress relief and sore muscle recovery. They also aid in improving circulation.

Hidden Color Bath Bomb Recipe Notes:

My hidden color bath bomb recipe makes a total of four hidden color bath bombs. I was able to use the pineapple bath bomb mold in addition to the two-part small round mold and the leaf and tulip molds. I started with the pineapple bath bomb mold first. Then, once I had made that bath bomb, I filled the other molds with colors at random.

Instructions for My Hidden Color Bath Bomb Recipe:

Begin by melting and mixing the liquid ingredients. To do this, weigh out the shea butter and babassu oil. Then combine in a heat safe container. Heat at 30% power in the microwave, or using the double boiler method, until melted. Remove from heat. Then weigh out the polysorbate 80 and fragrance oil. Stir into the melted oil and butter. Set aside.

Next combine and mix the dry ingredients called for in my pineapple hidden color bath bomb recipe. (A face mask is recommended for this step.) Weigh out the citric acid, baking soda, cream of tartar and magnesium flakes. Combine in a large bowl and mix well, ensuring all the ingredients are evenly combined throughout.

Now set out three separate bowls. Divide the dry bath bomb mixture between the three molds – one for each of the three colors.

Ingredients and bath bomb colorants for mixing and making hidden color bath bombs.

I used a large amount of the dry mixture for the pink mica. The dry mix for the blue lake dye had the least amount. While the green mica was about double that of the blue. Add the bath bomb colorants to each of the containers and mix well to combine. (The blue lake dye should account for about 28-34% of the dry bath bomb mix. Simply adjust the amount called for as needed.)

If desired, you may also add a bit of biodegradable eco-friendly glitter to any of the bath bomb colors.

Now add the liquid bath bomb mixture to each of the containers. Start with one color at a time. Use just enough of the liquid mixture to give the dry ingredients the consistency of wet sand. Mix well to combine then follow with the remaining colors.

You’re now ready to begin making your hidden color bath bombs.

Summer pineapple hidden color bath bomb being made by piling the different bath bomb colors into a heavy duty pineapple bath bomb mold.

I started with the pineapple bath bomb as it was the largest of the molds. Begin by loosely piling the green bath bomb mixture into the top of the mold where the leaves are. Then loosely fill the bottom portion of the mold with the pink mixture. Next, gently press – but don’t pack – the pink mixture into the mold.

Now loosely add some of the blue bath bomb mixture to the mold on top of the pink mixture. Press it slightly into the pink bath bomb mixture without packing it into the mold.

Follow with a loose pile of pink to cover the blue. Now firmly press and pack the bath bomb into the mold.

Once you’ve made your pineapple hidden color bath bomb, follow with the remainder of the molds, filling the colors as desired.

Allow the bath bombs to dry overnight or over the course of several days depending on the humidity in your area. (I left all of my hidden color bath bombs in the molds overnight with the exception of the round bath bomb mold. I was able to unmold that one right away.)

Then remove from the molds and package as desired.

Tips for removing the hidden color bath bombs from the molds.

If you have trouble removing your hidden color bath bombs from the pineapple, leaf and tulip shaped molds, simply bang the edges of the molds onto a table or hard surface on each side. At that point the bath bombs should come out of the molds in one piece. (You can also freeze them first to make removal even easier. Simply place the filled bath bomb molds in a gallon sized ziplock bag, then freeze for an hour before removing.)
