Common Bath Bomb Ingredients


ingredients to make the perfect bath bomb




Like with any other project or recipe you carry out, to get the most out of the ingredients, you have to understand them and what they provide to the final product. Making bath bombs seems easy, but the more ingredients you add to get the desired effect the more crucial it is that you understand the ingredients you are using.


Baking Soda (Sodium Bicarbonate)

This one is probably the most well known ingredient in a bath bomb and essential to being successful making them. A common ingredient seen in baking, it is also well known for it's use in many cleaning products, as well as things like toothpaste.

I recommended when making bath bombs to go with a reputable brand like Arm and Hammer. You want baking soda with fine granules, the less clumpy these ingredients, the better off you'll be. Baking soda is soluble in water and composed of sodium and bicarbonate ions. Best off it's super cheap!






Citric Acid

The other essential ingredient for success is your Citric Acid (unless using milk powder). When combined with the baking soda and placed in water, this is what gives you the fizzing reaction.

Citric acid is natural in fruits and is a weak organic tricaboxlic acid. Like with baking soda, you really want this in the finest powder you can find.

We buy our citric acid right from Amazon.com. It's inexpensive and you can find many reputable brands. Baking soda and citric acid are skin safe ingredients.


Salts (Epsom Salt)

Another common ingredient you will find in bath bombs are salts, like Epsom salt. These types of salts contain certain minerals that help to soften, and heal the skin. You can use fine sea salt or coarse, like Epsom salt.






Clay's

Some clay's are better then others, but this additives is amazing because it has 2 great benefits. Number one clay is skin safe and great to soak in as it has a detoxifying effect, but it also helps to draw moisture out of your bath bomb and make for a rock solid end product (literally).

Now keep in mind many of these Clay's like Kaolin clay will make your mixture dry much faster and you will find yourself adding much more binder (water/alcohol) and much more often.






Cream of Tartar (Potassium Bitatrate)

Another efficient hardener is cream of tartar, which you can also find in a lot of baking recipes. Usually the end product is not quite as hard as kaolin clay, and less binder is needed, but it still results in harder bath bomb then without.






Corn Starch

This is one ingredient that most people add to their list of essentials, however it's debated in the "bath bomb" world if it's actually an essential product. So I would say it depends.

Corn starch to me is not absolutely essential, however what corn starch does in a bath bomb can be important depending what you want your end product to do. For instance, if you want your bath bomb to dissolve slower and float then corn starch is an additive that's more essential to your mixture because it slows down the reaction between baking soda and citric acid when placed in water.

If that's not important to you then don't add corn starch to your recipe. We tend to include corn starch, however at much lower amounts then many recipes call for, it's really just preference.






Oils

Oils are another one of those ingredients that's based on preference. We typically don't use a lot of oils, but common oils you see in bath bombs included; coconut oil, avocado oil, grape-seed oil, sunflower oil, olive oil, sweet almond oil (personal favorite) and Shea butter.

These oils are nice in the fact that they add another softening and hydrating element to your bath bombs, leaving the skin feeling silky smooth. My thought process behind them is that if you choose to use them, a little goes a long way!

Keep in mind there is also a difference between oils, some are light, some are medium and some are heavy oils. While each of these categorize of oils serve a purpose, they can also effect the weight of your end bath bomb, which means there is a greater chance of it sinking if your density is higher then that of water.






Tip: If you're selling bath bombs and using oils, you must place a warning about the hazards of slipping in the tub. Oils can make the bottom of a tub very slippery, and that's why we tend to use with caution.



These are the most common ingredients you will see in all bath bombs.
