A few years ago, I started making my own bath fizzies or bath bombs. It's actually a rather simple process. You mix together the various ingredients until you the mixture is the right consistency to hold it's shape when pressed together. It is pressed into a mold and then allowed to dry until it is rock solid. That is the basic process. Of course, there is a myriad combinations of skin conditioning ingredients, scents, colors, molds and textures that can be incorporated into the basic scheme to produce a very unique bath fizzie and satisfying bath experience.
The basic recipe for bath fizzies:
1 Cup Baking Soda
1/2 Cup Citric Acid
1-2 Tablespoons of an emollient oil or melted bath butter of your choice.
1/2 teaspoon - more or less - essential or fragrance oil
Coloring - a tiny dab of paste food coloring diluted in a minute amount of H2O
Witch Hazel in a bottle with an attached sprayer
If you are sensitive to dust, you should use a disposable dust mask.
The basic steps are as follows:
1. Measure Baking soda into a large mixing bowl.
2. Blend the emollient oils into the baking soda. I like to use a large spoon to smash and stir the dry ingredients until the oils are evenly mixed into the baking soda.
3. Measure and add the Citric Acid. Thoroughly stir until completely incorporated into the baking soda mixture.
4. Dilute the food color with a tiny amount of water and then add to the witch hazel in the bottle.
5. Alternately spray witch hazel into the dry ingredients while quickly stirring the mixture until the fizzie mixture will hold shape in a mold. Be careful not to wet the mixture so much that you prematurely activate the chemical reaction responsible for the bath bomb fizzing. It is very important to immediately stop spraying the witch hazel and stir the dry ingredients vigorously if any fizzing takes place.
6. When the mixture has absorbed enough witch hazel to allow it to be molded, press the mixture into the mold of your choice.
7. Let fizzie mix sit in the mold for a minute and then very gently, release the fizzies from their mold.
8. I like to line a cookie sheet with wax paper while I allow them to dry, at least overnight.
9. When completely dry, store in a container.
There are a lot of variations that can be used to create a custom bath fizzie. Some of the possibilities include incorporating other emollients such as glycerin, emollient oils, melted coconut oil or vegetable butters into the mixture.
Dry ingredient alternatives include adding finely ground oatmeal, Epsom salts, dry milk powder(for a milk bath), corn starch or just use your imagination.
On a whim, I've added finely ground lavender buds to my bath fizzies. What a delightful treat that was!
Bath fizzie bases can be molded into a myriad shapes such as hearts or flowers. Sizes can range from a softball size to a mini lozenge size.
I've seen pictures of fizzies offered on the Internet that are spray painted on the outside or have coordinating scent and color combos incorporated into a single bomb. Haven't tried it myself, but think they look pretty cool.
One of the friends I had gifted the lozenge size fizzies to made sachets out of a few to keep as drawer fresheners. She took different colors of Tulle and decorative ribbons to hold the sachet/fizzie and then put them into drawers and linen closets.
Children and Tweens can really get into this project too! Group dynamics can really get charged when the kids figure out that the bath fizzies are very similar to the vinegar and baking soda volcano science experiments we all remember from our childhood & that all they need to do is add water.
In any event, my frustration in locating certain essential oils, fragrance combinations & other materials for this project led me to embark on the study of niche perfumery.
