Bath Bomb Recipes

While there are MANY variations on Bath Bomb recipes covered in my Atomic Bath Bomb Book, there are some commonalities.

Typically the ratio is:

For skin softening, ingredients may include a variety of light oils, or butters such as mango, coconut, or shea.

Some General Notes:

For skin softening, you may want to include a variety of light oils, or butters such as mango, coconut, or shea.
The addition of oil helps bind the dry ingredients together, and can help hold your mixture together when compressed. Some recipes include alcohol and glycerin mixes as a binder. While they may work fine, bear in mind that these items are hydroscopic, and will absorb water from the air.
When storing your bath bombs, remember to keep them in an airtight container to prevent them from "blooming" (absorbing water from the air, causing premature reaction).
Sodium Lauryl Sulfoacetate added in a 10-15% ratio can add lots of wonderful, foamy suds to your bath. It can also help extend the fragrance of your bath bombs.
Milk powders are great for adding a silky feeling to your bath, but they tend to minimize the amount of fizzing of bath bombs. For best results, use milk and yogurt powders sparingly.
Sifting your dry ingredients together helps create a smoother blend. The addition of Epsom or Sea Salts will make your blend more coarse, but will also serve as a softening agent in the bath.
Take caution if you elect to color your Bath Bombs. Be sure to use only soap-safe colorants. Some newer design tubs have been known to stain -- so use color sparingly! You may elect to add color to your creations with the addition of herbs or botanicals, as opposed to colorants.
