Supplies Needed for DIY Bath Bombs:

IMPORTANT NOTE:

The amount of fragrance oil and/or essential oil that will need to be added to your bath bomb mixture can vary widely depending on what you are using. Generally, fragrance oil can be added to the bath bomb mixture in 1/2 teaspoon increments until the desired amount of fragrance is reached. Essential oils are often far more potent than fragrance oil, so we recommend adding 15-20 drops of essential oil to each recipe to start and then adding more in 5-drop increments until the desired level of fragrance is achieved. 

How to Make Red and White Striped Bath Bombs:

Adding dry ingredients to a mixing bowl to make bath bombs

In a large mixing bowl, thoroughly combine the baking soda, cream of tartar, and SLSA powder.

Divide the dry mixture evenly into two medium bowls, and stir the red mica colorant into one of the bowls. Leave the second bowl uncolored.

In a small container (a 2-oz shot glass works great!), combine 1 tablespoon of fractionated coconut oil, 1/2 tablespoon of Polysorbate 80, and half of your fragrance or essential oil. Stirring constantly, slowly mix the liquids into the red dry ingredients until they are completely combined.

In a second small container, combine the remaining fractionated coconut oil, Polysorbate 80, and the remaining fragrance/essential oil. Stirring constantly, combine the liquid ingredients with the dry white ingredients.

Add 3/4 cup of citric acid to each of the bowls, and stir until it is fully incorporated into the mixture.

testing the bath bomb mixture firmness in hand

Test to see if the mixture is a moldable consistency – it should feel like slightly damp sand and hold together when squeezed in your hand.

If the mixture is not quite wet enough to mold, spritz it two to three times with a misting spray bottle of witch hazel and mix well. Repeat as necessary until the proper consistency is reached – it doesn’t need to be very wet, so don’t overdo it!

When both colors are ready to mold, fill both halves of the bath bomb mold with alternating stripes of the red and white mixtures. Make sure to overfill both sides of the mold a bit so that there is a slight mound to the top. Press both halves of the mold firmly together.

Carefully release the bath bomb from the mold (you can use a wooden spoon to lightly tap the exterior of the mold to help release the bath bomb, if necessary), place the bath bomb onto a cookie sheet or an egg-crate foam sheet and allow it to dry completely – this may take anywhere from 12-48 hours depending on the temperature and humidity of your location.

Frequently Asked Questions On How To Make Bath Bombs

What’s The Best Method For Drying Bath Bombs?

My technique for unmolding and drying bath bombs is this:

When unmolding round bath bombs, begin by carefully removing the top half of the metal mold. Allow the bottom half of the bath bomb to remain in the lower mold section while the top half begins the drying process. This technique prevents the bottom of the bath bomb from flattening, which can happen if you immediately place it on a flat surface like a baking sheet after unmolding.

After one hour, flip the mold to expose the opposite side of the bath bomb. After a total of two hours, remove the bath bomb from the mold completely. For thorough drying, place the bath bomb on a foam egg crate sheet and leave it to dry for 24 to 48 hours.

IMPORTANT NOTE:

Do NOT allow each half of the bath bomb to dry inside of the mold for longer than an hour! Exceeding this time may cause the bath bombs to become stuck inside the mold!

How Long Do Bath Bombs Last and Stay Good For?

Bath bombs typically have a shelf life of around six months to a year when stored properly. This lifespan can vary based on the ingredients used and the storage conditions. To maximize their shelf life, always store bath bombs in a cool, dry place away from moisture, as humidity can prematurely trigger the fizzing reaction and reduce their effectiveness. Additionally, if bath bombs contain any oils, these can become rancid over time, so it’s best to use them while they’re fresh for the best experience.

These Cat in the Hat bath bombs use fractionated coconut oil which can last for a minimum of two to three years, if not longer, when stored properly. That means that these particular bath bombs will be good for at least two years, though the fragrance and fizzing/bubble reactions will be the strongest within the first 12 months.
