What are Bubble Bars?

Bubble bars are a fun bath time treat. I would describe bubble bars as a solid bubble bath. Bubble bars disintegrate in water and contain a foaming agent that creates mounds of foam and bubbles. Whereas bath bombs generally only fizz and don’t produce much foam.

Ingredients for Bubble Bars

You probably already have most of the ingredients for my solid bubble bath recipe. Here’s what goes into them:

  • Baking Soda and Citric AcidBaking soda and citric acid are responsible for the fizzing reaction and make the bulk of this bubble bar recipe.
  • SLSA (Sodium Lauryl Sulfoacetate) – SLSA is a natural detergent, derived from coconut and palm oils, and acts as the foaming agent. Unlike SLS, SLSA has a large particle size and can’t penetrate the skin. The ingredient is considered a mild, skin-friendly cleanser, unlikely to cause irritation.
  • Shea ButterShea butter holds the bubble bar mixture together. The plant butter also is also deeply moisturizing and will make your skin feel soft and nourished.
  • Emulsifier – We also need to add an emulsifier to disperse the shea butter, essential oils, and colorant in the bathwater. Without an emulsifier, the oils will pool on the water surface, and the mica powder will leave a ring on the tub. I used Polysorbate 80, which is readily available and works well in this homemade bath product.
  • Essential Oils (optional) – Essential oils provide a natural fragrance. You can find a few blends below.
  • Mica (optional) – To create a tie-dye effect, I used pink and blue mica to tint portions of the bubble bar. Of course, you can choose other hues or omit the colorant. Alternately you can also make rainbow bar embeds for your DIY bubble bars.
  • Biodegradable Glitter (optional) – Biodegradable glitter makes this bubble bar recipe shine and sparkle.

These DIY unicorn bubble bars are the perfect gift for Lush lovers. Enjoy pampering self care at bath time with a fragrant bath filled with moisturizing shea butter and a relaxing natural essential oil blend that's kid-safe.

Equipment Needed to Make Solid Bubble Bath

To make these DIY bubble bars, assemble the following equipment and tools:

  • Mouth Cover – SLSA is a fine, airborne powder that can irritate the airways. For this reason, cover your mouth and nose with a face mask or another form of protective covering.
  • Nitrile Gloves – Raw citric acid can be stinging and damage nail polish, so I recommend putting on nitrile gloves to protect your hands.
  • Mixing Bowl and Measuring Cup – A large glass mixing bowl and heat-proof glass measuring cup are best to melting and mixing the ingredients.
  • Spatula – A spatula or spoon is perfect for mixing the bubble bar mixture.
  • Cookie Cutter – My easy method for making bubble bars at home uses cookie cutters to form the bubble bars. I opted for cute unicorn cutters. Of course, you can pick whatever shape you like. It’s also a good idea to mix different shapes and sizes to create an interesting variety of bubble bars.

How to Make Bubble Bars

Now that we have gathered our supplies and tools, it’s time to make bubble bars! Don’t be intimidated by the process. Making bubble bars at home is easier than you think, and I’m here to explain every step to create the perfect unicorn bubble bars.

Melt Shea Butter

The first step is to melt the shea butter. You can either melt the shea butter in a water bath or in the microwave. Here is what you do:

  • Water Bath: Fill a small saucepan or double boiler 1 in with water and bring to a gentle simmer. Place the shea butter in a heat-proof container (I used a large glass measuring cup) and heat in the water bath until melted.
  • Microwave: Place the shea butter into a microwave-safe dish. Heat on medium for 30 seconds. Take out and stir. Continue this process until the shea butter has completely melted.

Be careful when handling melted shea butter because it can be quite hot.

Add the Essential Oils and Emulsifier

Let the shea butter cool on the counter for 10 minutes. Then add in the essential oils and emulsifier. Give the mixture a good stir to ensure that the liquids are well combined.

Mix Dry Ingredients

First, put on a face mask and gloves. Add the baking soda, citric acid, SLSA, and glitter into a large glass mixing bowl. Stir to combine.

Tip: If the baking soda and citric acid are lumpy, sift them first.

Make Bubble Bar Mixture

To make the bubble bar mixture, pour the melted shea butter over the dry ingredients. Stir until the mixture starts clumping together. Then continue to knead with your hands until it resembles the texture of cookie dough, and no lumps remain.

At this point, feel free to take off your facemask. The SLSA is now bound, and there’s no risk of inhaling the tiny particles.

Color the Mixture

To make unicorn bubble bars like you see in the pictures, cut the bubble bar mixture into half, and then cut one half into quarters. Tint one quarter portion pink and the other quarter portion blue. The half portion remains white.

Flatten The Bubble Bar Dough

Work on a clean, flat, non-stick surface (I used my kitchen countertops), mix the colors, and flatten the bubble bar dough with your hands. Form a disk that’s about 1/2 inch thick.

Cut Out Bubble Bar Shapes

Using cookie cutters, cut out your bubble bars. Since the bubble bar dough is still soft at this point, avoid lifting the bars. Instead, cut out shapes near the edge and then pull the cookie cutter away from the center. Remove any excess dough and then lift the cutter to release your bubble bar.

Optionally, sprinkle the bubble bar dough with glitter before cutting out shapes.

Continue this process with the scraps until all of the dough for your unicorn bubble bars is used up.

Dry the Solid Bubble Bath Bars

Leave the bubble bars to dry for several hours or overnight, and you’re all done. Typically, bubble bars take between 48 and 72 hours to dry. However, as these bars are thinner than most solid bubble bath bars, they may be ready in as little as 6 hours.

However, if your bubble bars aren’t fully dry after 48 hours, simply give them additional time, as humidity and other conditions can affect drying time.

Once your solid bubble bath bars are dry, they will be hard to touch, and ready to use.

How to Use Bubble Bars

There are several ways to use bubble bars:

  • Fill the bathtub with warm water and drop one bubble bar in. The bubble bar will fizz and dissolve. You can help the process by swirling it around.
  • You can also crumble the bars under the running tap while the bath fills up.
  • Regardless of which method you choose to dissolve your bubble bars, be sure to swish and twirl the water with your hands to create more foam and bubbles.

Tips for Gift Giving and Packaging Ideas

Unicorn bubble bars are adorable homemade gift ideas. They are sweet presents for kids, Galentine’s, or thank-you favors for a baby shower, bridal shower or birthday.

For gift wrapping, package the bubble bars in favor bags and decorate each bag with colorful ribbons or twine. I found the cutest unicorn gift tags on Etsy that go perfectly with these DIY bubble bars:

Storage and Shelf Life

Store the bubble bars in an airtight and waterproof storage container in a dry, cool place. I keep mine in a Tupperware box, but Ziplock bags or large mason jars would work, too.

I don’t store my bubble bars in the bathroom as the moisture in the air (e.g. steams from the shower) can cause them to dissolve. Wrap them tightly in plastic wrap for extra protection.

Although all ingredients have a long shelf life, citric acid loses its potency over time. I recommend using your DIY bubble bars within 6 months.

Yield: 8 to 12 bubbles bars (depending on size of your cookie cutter)

    This recipe as written didn’t give me cookie dough consistency, I had to add a lot more dry ingredients, not sure why. They are hardening up tho so hopefully they turn out ok!

      It could be the shea butter was too warm and just needed additional time to cool. Something as simple as room temperature could affect this. Also shea butter tends to have a range of melting points especially with refined vs unrefined that may require some minro tweaks, as natural products are never entirely consistent. A high melt point point refined shea butter is best but other types should work as well.

        Hi, made these last night & still soft. I have them stored in an air tight box- will they dry in there

        1. Rebecca D. Dillon

          April 27, 2021 at 1:44 pm

          I’d wait until they dry before storing them.

    It looks super cute.
    Can i use 1/4 cup slsa in place of 1/2 cup.?
    will it make a diffcwhike binding the mix.
    Thank you.

      You can reduce the SLSA. However, you’ll need to proportionally increase the other dry ingredients to make up for the difference, or reduce the amount of shea butter you use.

    Can you replace Shea butter with coconut oil or cocoa butter?

    1. Rebecca D. Dillon

      March 19, 2021 at 11:54 am

      Both of these have very different melt points than shea butter. Coconut oil has a melt point that’s likely to low to be used solo, however, it may be possible to use cocoa butter, though you may need to add another ingredient to lower the melt point. It would require some experimentation however as you wouldn’t be able to make a straight swap for the shea butter.
