Once you have made bath bombs a time or two, you will find them quite easy to make and you will save yourself some money while you are at it.
Not only that, by making them yourself, you’ll know exactly what’s in them. Not all commercial or artisan-made bath bombs are all-natural, but you can make virtually all-natural bath bombs at home that fizz amazingly well. Making them yourself will also save you at least half the price of what equivalent bath bombs cost from artisans and bath bomb specialty stores.
The key ingredients here are Citric Acid, Baking Soda & Food Coloring/Pearlescent Micas… (Say what? Let us explain..)
Citric Acid: Citric acid is naturally found in citrus and other fruits/vegetables. As it’s name says… it is acidic. No worries though, citric acid acts as a natural preservative and natural antioxidant and is found in an array of skin care products.
Baking Soda: Baking soda is the common name for sodium bicarbonate or bicarbonate of soda. Sodium bicarbonate is a naturally forming salt, but is most commonly manufactured synthetically. Because it is a salt that exists in nature, it’s often considered natural, regardless of manufacture, and is used in natural products. In personal care, baking soda is known for its deodorizing and cleansing properties. Baking soda is a alkali that reacts wonderfully with citric acid in bath bombs.
Food Coloring or Pearlescent Micas: Bath bombs don’t need to be colored to be fun, and effective, but color can add an aesthetic touch to your creations. You can use food coloring but Pearlescent micas might be better for you. They contain naturally forming mica powder colorized with minerals like iron oxides and titanium dioxide. Pearlescent micas can have synthetic color additives, so its best to purchase it from a reputable source and check the ingredients of each particular mica that you use.
