Description

The dark purple hue in these bath bombs is created with Plum Dusk Mica and Queen's Purple Mica, with a touch of Fine Silver Rainbow EcoGlitterCoconut oil gives the bath bombs shape and firmness, while polysorbate 80 helps disperse the oil and micas in the bath water.

Once the bath bombs completely harden, they are removed from the mold. A combination of Gold Sparkle Mica and 99% isopropyl alcohol create a paint that's used for the crescent moon shape. 

Because these bath bombs contain quite a bit of mica and sparkle, they may leave some color behind on your tub. Mica clings onto dirt and grime, so giving your bath a quick wipe down before use will help prevent this. The polysorbate 80 also helps the mica disperse throughout the water rather than pooling on top. We don’t recommend skipping the polysorbate 80 for this recipe.

Crescent Moon Bath Bomb Project
Inspired by crescent moons, these bath bombs feature plenty of sparkle and a fresh scent.

Ingredients

7-8 Disk Mold & Packages
2 cups Sodium Bicarbonate (Baking Soda)
1 cup Citric Acid
2 oz. Coconut Oil
0.2 oz. (about 9 mL) Polysorbate 80
9 mL Moon Child Fragrance Oil
1 tsp. Queen’s Purple Mica
1 tsp. Plum Dusk Mica
1/2 tsp. Fine Silver Rainbow EcoGlitter
1 tsp. Gold Sparkle Mica
Witch Hazel in Spray Bottle
99% Isopropyl Alcohol 
Dropper

Instructions

1

Melt the bag of coconut oil in the microwave using 30-60 second bursts. Pour 2 ounces of coconut oil, 9 mL of Moon Child Fragrance Oil, and 9 mL of polysorbate 80 into a small, fragrance oil-safe container. Use a spoon to fully mix the ingredients together.

2

In a large bowl, mix together 2 cups of baking soda and 1 cup of citric acid. To get rid of clumps in the mixture, you can push the powders through a sifter or break them up with your fingers. Citric acid has a tendency to take off nail polish, so wear gloves to protect your manicure. Thoroughly stir the ingredients together. Add 1 teaspoon of Plum Dusk Mica, 1 teaspoon of Queen’s Purple Mica, and 1/2 teaspoon of Fine Silver Rainbow EcoGlitter to the powders and stir to incorporate.

3

Add the oil mixture to the powder mixture. Use your hands to fully mix the ingredients together.

4

Test the consistency of the bath bomb mixture. The perfect consistency for molding is similar to wet sand and holds its shape when squeezed. If it’s too dry, use one hand to spritz the mixture with witch hazel and one to mix. Continue spritzing until the mixture holds its shape.

 

5

Fill the Disk Mold and Packages with the bath bomb mixture. Firmly compact the mixture in to create a solid shape. Only fill each mold to the inner lip, or the lid will not close. Allow the bath bombs to dry and harden for at least 4 hours or up to overnight. If unmolded too quickly, they may fall apart.

6

Once the bath bombs are completely dry and hard, remove them from the molds. Mix 1 teaspoon of Gold Sparkle Mica with 1 tablespoon of 99% isopropyl alcohol to create a paint. Place the bottom of mold on top of the bath bomb to create a crescent moon shape and paint on the gold. If you find the mica paint is bleeding, add more mica to thicken. If it’s too thick, add a bit more 99% isopropyl alcohol to thin.

7

Continue this process with each bath bomb. Allow the paint to fully dry. The painted moons on top of the bath bombs will transfer mica when touched, so handle carefully. To use, place the bath bombs into a hot bath and enjoy!
NOTE: Because these bath bombs contain quite a bit of dark mica, they may leave behind some color on your tub. Mica clings on to dirt and grime, so giving your bath a quick wipe down before use will help prevent this. The polysorbate 80 also helps the mica disperse throughout the water rather than pooling on top.
