So What Exactly Are Bath Bombs?
Bath bombs become fizzy in your bath and deliver pleasant smells and sometimes other vitamins, minerals, & herbs to calm and soothe your bathtime. Once a niche market, bath bombs have become increasingly popular because the ingredients are designed to help with various different maladies, including stress, insomnia, and detoxifying your body.
Bath Bombs usually contain three main ingredients: citric acid, cornstarch, and baking soda, according to chemistry professor, Frankie Wood-Black of Northern Oklahoma College. Sometimes bath bombs also include colored dyes, perfumes, and epsom salt to make them extra fancy.
Ingredients Inside Bath Bombs
When you purchase a bath bomb, there are many varieties. But they will all come with some basic ingredients to make them fizzy and last during your bathtime. Let’s discuss the main ingredients in bath bombs.
- Epsom salt (also known as magnesium sulfate) is probably something you’ve heard of – it’s composed of sulfur, magnesium, and oxygen.
- Uses: For hundreds of years, it’s been used to treat insomnia, fatigue, muscle pain, and fibromyalgia, but it’s important to note that these benefits haven’t been really researched as treatment.
- While some people do drink it (not recommended), most people use epsom salt soaks as a way to manage stiffness, muscle pain, and swelling
- Sodium bicarbonate is a combination of citric acid and baking soda. This is what gives the bath bombs that fizzy consistency when the citric acid and baking soda are introduced into the bath water.
- Uses: The results of these ingredients hitting the water (through some amazing chemical reactions) is the release of carbon dioxide gas, which forms the bubbles in the water, eventually giving you that delightful fizzy feeling.
- Cornstarch is another ingredient it’s likely that you’ll see listed on the label of your bath bombs and it serves a very important purpose.
- Uses: to slow down the chemical reactions so that the fizz (carbon dioxide – a gas) last longer.
What Are Some of The Ingredients You Should Avoid?
We found a major problem when researching bath bombs. There’s a ton of bath bombs that are sold online that do not share their exact formula of each bomb – even though there are ingredients in there that differ from bomb to bomb. We’ve been asking around and emailing companies, but so far, we’ve not gotten much of a response.
However, the bath bombs themselves often do list the ingredients within the individual bath bomb – trouble is, you’d have to buy it first. (So if you purchase ones that we don’t list, tell us what the ingredients are in the comment section please.)
Here’s a list of what ingredients to avoid in your bath bombs:
- If You Have Sensitive Skin: avoid limonene, linalool, & alpha-isomethyl ionone because they are irritants according to cosmetic chemist Randy Schueller, the editor of thebeautybrains.com.
- Undisclosed Fragrance–The thing about “fragrance” is that it’s not a term regulated by the FDA, therefore the company making these bath bombs can hide plenty of toxins in a “proprietary” blend of ingredients. Some of these “fragrance” ingredients have even found themselves on the EPA’s Hazardous Waste list. What tends to hide inside fragrance is phthalates, which have been found to decrease sperm quality and affect hormone levels in both men and women. Phthalates are currently being linked to obesity, ovarian aging, and certain forms of cancer.
- Artificial Colors & Dyes: Just about every decade, studies come out that show the dangers of a particular color – in fact, since 1906, when we had 80 approved colors to use, we are now down to 7 approved by FDA. This is because the hidden dangers in colors and dyes have come to light – anything from carcinogens, migraines, and anxiety – have been found to likely correlate with a particular color that is eventually removed by the FDA as approved.
- Benzene & Its Derivatives These compounds can cause cancer, believed to cause reproductive malformation, and disturbances in your body’s hormones. There are a great number of benzene derivates, so I found a handy little chart for you to look at.
- Aldehydes & Their Compounds, which include formaldehyde, butyraldehyde, acetaldehyde, benzaldehyde, crotonaldehyde, acrolein, propionaldehyde, valeraldehyde, butyraldehyde, isodecaldehyde, are compounds thought to cause liver disease and embryo toxicity.
- Parabens which are endocrine disruptors. Often, you’ll find more than one paraben in a single product. Some of the other names to look for are methylparaben, ethylparaben, propylparaben, and butylparaben.
Are There Any Dangers Using Bath Bombs? Yes, For Your Vagina.
Whelp, here’s the thing – the beautiful colors and smells of our bath bombs are what the biggest problem in using any type of in-bath products: bath bombs, bath fizzies, bubble bath – even the organic, vegan varieties.
As we know, bath bombs contain perfumes and dyes to achieve that brilliant color and smell combination, however, these products can mess with the pH levels of our vaginas. Just like douching.
Not only can these affect our vaginal pH, but it can also kill off the good bacteria living in your vagina while leaving your vagina prone to yeast infections and urinary tract infections.
And some of the more high-end bath bombs contain glitter, which are very abrasive in an area you don’t want to scratch up.
So treat bath bombs like treats. If you’re one of those people who are prone to yeast infections and/or UTI’s, we suggest avoiding using bath bombs entirely.

Better Bath Bombs
These brands are better than the ones before, but we still found some issues. We allowed some additives in this category like polysorbate 80. These brands may also not be disclosing all their fragrance ingredients. They may be using “natural” fragrance, but we don’t know what’s inside and that may be bad for people with sensitive skin or allergies. They also could be using artificial colors.
