Fizzy Bath Salts Recipe

These fizzy bath salts are similar to bath bombs, but much easier and less time-consuming to make. It’s fun to pour them into the tub and watch them do their thing- especially if you add food coloring. The kids love this recipe too!

Ingredients

A. Pure Unscented Epsom Salt (magnesium sulfate)

B. Baking soda (sodium bicarbonate)

C. Citric acid

D. Sweet almond oil (or jojoba oil, vitamin E oil or fractionated coconut oil)

E. Jasmine Essential Oil (or other essential oils of your choice)

F. Food coloring (optional)

Tools

A. medium mixing bowl

B. small bowl

C. nitrile gloves (optional)

D. fork and spoon

E. measuring cups and spoons

Packaging

A. 3 inch wood scoops

B. glass jars with airtight lids (these are the ones I’m using)

C. chalkboard sticker labels (I love this brand & use them on everything!)

D. white paint pen

Directions

1. Combine dry ingredients.

Combine the epsom salt, baking soda and citric acid in a medium mixing bowl and stir well.

2. Combine oils.

Add essential oils to carrier oil (I’m using sweet almond oil) in a small bowl and stir.

3. Add oils to salt mixture.

Pour the oils into the salt mixture. Stir with a fork, and then mix with your hands.

4. Add food coloring.

Add a few drops of food coloring. If you want a fun galaxy effect, use 2-3 different colors that are near each other on the color wheel. I’m using purple, blue and pink.

Use gloved hands to mix and sift the colors in until you have a fairly even distribution. There will still be specks of the individual colors. Note: The gloves are just to prevent you from dying your hands purple.

5. Fill jars.

Spoon the finished bath salts into jars. You never want to pack them down like brown sugar, as this will form a bath salt brick.

Bath Salt Storage

Bath salts should always be packaged and stored in airtight containers. Otherwise the salt will absorb the moisture in the air and form large clumps- or worse, one big bath salt brick. So keep that lid on when you’re not using it!

Bath salts should be fine at room temperature, but it’s best to keep them out of direct sunlight. The fragrance from the essential oils will dissipate over time.

Helpful Tips

I prefer to use food coloring (you can get all-natural food colors here) over mica powder in my homemade bath products. I’ve found that the combination of mica powder and carrier oil usually leaves a mess in the tub, while a small amount of food color won’t. Mica is also expensive.
It’s fine to adjust the quantities of your ingredients slightly, but don’t overdo it on the oil, as this can make the tub slippery.
If you use more that a couple of drops of food color, I recommend spreading your finished salts out on a parchment or foil-lined sheet pan to dry for 24 hours before spooning them into jars or packages. This will help prevent clumping from the extra moisture.
