What are Bath Bombs?
A bath bomb is one of the most friendly skincare products you can buy to enjoy a great time in the bathtub. You must have seen lots of bath bomb ideas where the tub is lit with candles and filled with multiple colors. But what exactly are bath bombs?
A bath bomb is a spherical blend of fragrant and soothing oils and extracts that you throw into your tub before bathing. Its main ingredients are sodium bicarbonate (baking soda) and citric acid, which are the ones responsible for the fizzing effect that bath bombs create.
When you drop the bath bomb into the water, this reaction will happen and cause the bath bomb to dissolve completely and release all the goodies inside, from the awesome fragrance to skin-smoothing emollients, which helps soften the skin.
How Does it Work?
The “bomb” aspect of a bath bomb is the fizziness. But what’s going on in those spheres that make them so fizzy? Two of the key ingredients to a bath bomb are citric acid and sodium bicarbonate. You might also know sodium bicarbonate by its more common name, baking soda. These two ingredients are what cause the impressive and delightful fizz when the bath bomb enters the water.
When sodium bicarbonate (NaHCO3) comes in contact with water, the sodium (Na) molecules break off from the bicarbonate (HCO3). At the same time, the citric acid is dissolving, with a single hydrogen ion (H+) separating from the rest of the molecule. When the released hydrogen ion from the citric acid encounters the bicarbonate from the baking soda another reaction happens! This time, carbon dioxide (CO2) gas is released as one of the end products. The carbon dioxide forms bubbles in the soap and bath water, and rushes to the surface with a delightful fizz.
Are bath bombs bad for your vagina
There's good news: "Some women can use any bath bomb without issue," says Alyssa Dweck, M.D., ob-gyn and sexual and reproductive health expert for INTIMINA. But not everyone will be so lucky. "Many others are sensitive and will have increased risk of vaginal infection, urethral irritation, and UTI or vulvar skin irritation (vulvitis) due to the ingredients," she says.

the vagina is a self-cleaning organ and maintains its own ecosystem. It's highly susceptible to disruption by external agents (think: chemicals, fragrances, even soaps) because they can easily disturb your vaginal flora and shift your body's natural pH, increasing your risk of things like bacterial vaginosis (an imbalance of bacteria in the vagina) and yeast infections (and overgrowth of naturally occurring yeast in the vagina). Because your vaginal ecosystem can so easily be thrown off, it's really important to pay attention to what you're using in this oh-so-sensitive area.
So, if you're already prone to irritation, yeast infections, UTIs, or bacterial vaginosis, it may be safer to avoid bath bombs altogether and taking a look at what's inside your favorite one, says Dr. Dweck. Here are some ingredients that Dr. Dweck says you might want to avoid:
-
Heavy fragrance or dyes: These chemicals can lead to irritation and pH imbalances within the vagina. This can cause discomfort or even bacterial vaginosis. They often appear as "fragrance" or things like "Blue 2" or "Red 4" in ingredient lists.
-
Talc: Talc has a possible link to ovarian cancer, although this idea is debated among medical professionals and researchers. Best to steer clear, just in case.
-
Parabens and phthalates: Dr. Dweck described these as endocrine disruptors, meaning they can interfere with your hormonal functions. Many endocrine disruptors are also hazardous for the environment, so overall it's best to avoid them in any personal hygiene or beauty product.
-
Glycerin: Glycerin, a common ingredient in beauty products, breaks down into sugar. While, as a humectant, it's great to seal in moisture for dry skin, glycerin near your vagina can lead to an increased risk of bacterial vaginosis or yeast infections because some bacteria and yeast feed off of sugar, and introducing it to the area can least to yeast overgrowth. (Note: Glycerin is also found in many OTC vaginal lubricants, so make sure you're checking the ingredient list on those bottles as well.)
-
Glitter: It may also be a good idea to avoid bath bombs with glitter. Glitter is hard to clean off of anything (including skin) and may scratch the skin of your vagina. Ouch. (Sorry, I guess we all can't live out our fairy princess fantasies from childhood.)
It's important to note that brands claiming to be "clean" and "natural" still make products with these ingredients, so always check the ingredient list before making a purchase. When in doubt, go with a product with as few ingredients as possible, because then there will be fewer things to potentially cause a reaction.
