Let’s start creating some real pampering magic!

What’s in This Bath Bomb Recipe

Citric Acid

Citric acid is a naturally occurring acid that gives these bubbly treats their signature fizz and features added benefits like cleaning your skin and balancing the pH of your bathwater.

Almond Oil

Almond oil’s molecular structure helps bind the various ingredients together, while also diluting down essential oils so they won’t be too harsh. Plus, if you don’t feel like almond oil is quite right for your project, no sweat – it can be swapped out with any other type of carrier oil.

Emulsifying Wax (Secret Ingredient)

If you’ve ever wanted to make the perfect, most indulgent bubble bath, emulsifying wax should be in your ingredients. It’s our secret special ingredient for some satisfying bubble-blowing experience. It also allows all of your oils, mica powder, and water to mix in harmony.

Unicorn Essential Oil Blend

Unicorn essential oil blend has soothing citrusy and floral aromas that make it perfect for a spa-like experience. Not just pleasing to the senses, the magical blend of essential oils also provides calming and uplifting emotional benefits.

Mica Powders

Mica powder is a natural ingredient that is great for adding extra shine and brilliant hues. Whether you choose to beautify with red or shimmer in blue, mica powder will add sparkle and sophistication to any DIY bath bomb.

Baking Soda

Adding baking soda to your bath bombs creates the perfect fizzing effect that no pampering session would be complete without. Not only does it add an interesting element to your bathing routine, but it also has properties that can work wonders for soothing sensitive skin.

Cornstarch (or similar starch)

Bath bombs are one of life’s greatest luxuries – except for when the fizz wears off in a matter of seconds, that is! Luckily, adding cornstarch (or other similar starches) can slow down the reaction and prolong its fizz effects. Not to mention it has the added bonus of creating a silky sensation while you bathe.

99% Isopropyl Alcohol

If you’re making bath bombs, you may want to consider adding 99% Isopropyl Alcohol for a natural skin-care solution. This powerful ingredient helps bind all your bath bomb ingredients together. If you’re looking for an alternative, witch hazel, water, or more carrier oil would work just as well.

Things to Remember When Using This Recipe

Always dilute an essential oil when using it on the skin. This essential oil recipe is unlikely to cause skin irritation when diluted properly. If the oil has been oxidized (left with the cap off for long periods of time) it is more likely to cause skin irritation. Check out this dilution chart for diluting this essential oil properly. 

If you are pregnant, consult your doctor prior to use.

Unicorn Bath Bomb Recipe

Foaming Unicorn Bath Bomb Recipe + Secret Ingredient

Ingredients

  • From Simply Earth
  • 1 tbsp Almond Oil

  • ¼ tsp Simply Earth Emulsifying Wax

  • 6 drops Unicorn Essential Oil Blend

  • ¼ cup citric acid

  • Bath Bomb Mold

  • From Your Home
  • ½ cup baking soda

  • ½  cup cornstarch

  • 99% Isopropyl Alcohol (or witch hazel) in a spray bottle

Directions

  • In a medium bowl, mix together baking soda and mica powder.
  • Add cornstarch and stir until evenly combined. 
  • Using a small bowl in the microwave or double boiler, heat the almond oil and emulsifying wax until the wax is just melted. Add the essential oil and stir. 
  • Mix together the dry ingredients and the oil mixture until evenly combined. 
  • Squeeze the mixture in your hand. If it crumbles when you release it, spray in the isopropyl alcohol and mix. Repeat until the mixture holds its shape after squeezing it in your hand. 
  • Stir in the citric acid until evenly combined.
  • Place bath bomb mixture into the mold, lightly packing and overfilling each side. Push both halves of the bath bomb mold together. Remove the bath bomb from the mold and place it in a safe place to dry. Repeat to create a second bath bomb.
  • Once the bath bomb is dry, place 1 dash of fuchsia, violet, and yellow gold mica into three separate bowls. Add 1 tsp of rubbing alcohol to each bowl and stir well.
  • With a paintbrush, draw stripes and splatter mica mixture onto the bath bombs to create a fun design. 
  • To use, wipe down the sides of the bathtub then fill it with water. Add bath bombs and enjoy. Tip: Rinse down the sides of the bathtub as the water drains.

Tips for Making Unicorn Bath Bombs

1. Get the Right Consistency

The most important tip for making bath bombs is to make sure you get the consistency right. Once you have all your ingredients mixed together, squeeze the mixture into your hand. If it doesn’t hold together like a snowball, you need to add more isopropyl alcohol.

2.Consider Wearing Gloves

If you have sensitive skin, or nail polish, or are making bath bombs for someone else, you should wear gloves while making bath bombs. Citric acid can rub away nail polish and irritate some people with sensitive skin (however this typically isn’t an issue when it’s added to the bath).

3.Consider Wearing A Mask

Baking soda and mica powders are very fine powders. They will go airborne when you add them to your mixture. This can be irritating to those with sensitive lungs. This is true of clays and mica powders (or any other fine powder) you may be adding to your bath bombs. You can wear a mask while you make bath bombs to prevent irritation.

4.Humidity

Humidity can be a big factor in the success or failure of bath bombs. Try not to make bath bombs when it rains. If you live in a humid environment, run a humidifier while you make your bath bombs and while they dry so that the water in the air doesn’t cause them to react prematurely.

5.There’s No Such Thing As Failure in Bath Bombs

If your bath bomb mixture isn’t turning out visually how you’d like, don’t count it as a failure. You can still add your mixture to a bath for fizzy, bubbly fun. 

6.Clean Your Tub

Mica powder has a tendency to stick to soap scum on the sides of bathtubs. Adding emulsifying wax to this recipe helps prevent that, but it’s always a good idea to give your tub a quick clean before using a bath bomb. As the tub drains, wash down the sides of the tub to make sure all the mica powder goes down the drain rather than sticking to your tub.

TIP: If you’re worried about mica powder sticking to your tub, you can skip it and have a white beautiful bath bomb.
