I love a good detox bath to remove toxins from the body and help kids relax (especially before bed) but a bubble bath is so much more fun!
Unfortunately, many bubble baths available at the store contain ingredients that can cause more toxicity. This bubble bath recipe is a great way to give kids a fun bubble bath experience without loading them with toxins.
Why Not Conventional Bubble Bath?
Makers of conventional bubble bath know what they’re doing… those brightly colored fun bottles look quite tempting. They even have cartoon character heads on them! While I can’t blame any kid for wanting them, the ingredient list is not as attractive by a long shot.
According to the Environmental Working Group’s website, which ranks ingredients in personal care products from 1-10 (10 being most toxic), some of the most toxic ingredients in these bubble baths are:
- Fragrance – Concerns include allergies/immune dysfunction, irritation (skin, eyes, or lungs), organ system toxicity (non-reproductive), and ecosystem toxicity. Score = 8
- Propylparaben – Concerns include allergies/immune dysfunction, endocrine (hormone) disruption, developmental/reproductive toxicity, ecosystem toxicity. Score = 7
- Oxybenzone – Concerns include biochemical or cellular level changes, allergies/immune dysfunction, endocrine disruption, persistence and bioaccumulation (accumulation in the body), developmental/reproductive toxicity, organ system toxicity (non-reproductive). Score = 8
- Imidazolidinyl Urea (a formaldehyde releaser) – Concerns include allergies/immune dysfunction, cancer, and contamination. Score = 7
- Formaldehyde (from imidazolidinyl urea) – Locks in a 10 on the toxicity scale for cancer, allergies, and immunotoxicity.
There are a number of other ingredients found in children’s bubble bath including sodium laureth sulfate (which helps bubbles last longer) that are questionable at best.
Protecting the Skin (and Body)
The skin is our biggest organ and has its own microbiome that is very important to the body. I’m a firm believer that what goes on the skin is as important as what goes in the body (if not more so) since what goes on the skin can be absorbed. If the skin is so susceptible to toxins, it makes sense to keep conventional bubble bath away from kids (and adults too).
The problem that many naturally minded moms run into when their kids want a bubble bath (with the brightly colored bottles from the grocery store, no less) is that kids don’t understand why the answer is “no”. They just want to enjoy a bubbly, sweet-smelling bath (hey, I do too!).
The solution? Make a homemade bubble bath that only contains ingredients that are safe for kids and adults.
How to Make Your Own Bubble Bath
A few simple natural ingredients are all that’s needed to make your own DIY bubble bath:
- Liquid castile soap – Castile soap, a coconut-based soap, is the base of this recipe. On its own, castile soap doesn’t create very many bubbles (and they don’t last long).
- Vegetable glycerin – Glycerin is the ingredient that gives the bubbles a boost. It helps make more suds and also helps the bubbles last longer.
- Essential oils – A natural way to give the bubble bath a nice scent (without yucky chemical fragrances). They can also be used therapeutically (to enhance relaxation, for example).
Kids’ Bubble Bath Recipe
An all-natural bubble bath recipe to make bath time extra fun!
Ingredients
- ¾ cup liquid castile soap
- ¼ cup vegetable glycerin
- 5-8 drops kid-safe essential oils
Instructions
- In a small bowl, mix castile soap, glycerin, and essential oil. Pour into a glass jar for storage.
- Add 1 tablespoon at a time to running bath water until desired bubbles are achieved.
Full disclosure: This kids’ bubble bath recipe can produce a decent suds but it won’t be as bubbly as a conventional bubble bath.
A Note on Essential Oil Safety
Essential oils are highly concentrated substances and can cause harm when used incorrectly. Always dilute them in a carrier oil (water will not dilute them) before using topically. It’s also important to choose essential oils that are safe for children if adding them to a kids’ bubble bath recipe.
Some essential oils that are calming and safe for infants and children are:
- cedarwood atlantica
- clary sage
- juniper berry
- lavender
- mandarin
- sandalwood
Personally, I would avoid using any essential oils in the bath for infants under 3 months and use them sparingly (and diluted) until about 2 years of age. I never add essential oils directly to the bath but dilute them first as in the recipe above.
For a more detailed list of safer essential oils to use around kids, see this helpful post from the Plant Therapy blog, which is endorsed by Robert Tisserand. They even have a line of Kid-Safe blends to take the guesswork out of it.
How Often Can DIY Bubble Bath Be Used?
Since it’s made with natural ingredients, use this DIY bubble bath recipe as often as you like. But be aware that bubble baths (and bathing/showering in general) doesn’t need to be a daily activity for kids, as bathing too often can actually disrupt the skin microbiome and cause eczema and even asthma.
The idea is that washing too often removes microbes from the skin that would otherwise help the immune system develop optimally. Children who haven’t reached puberty yet can get away with one or two baths a week.
Is This Kids’ Bubble Bath Recipe Tear-Free?
Any castile soap, even Dr. Bronner’s Baby Mild, is not tear-free. So this recipe is not going to be tear-free (which is a good thing — I’ll explain).
The reason soap irritates the eyes in the first place is that soap has a different pH from the eyes. The eyes actually have a very small window of acceptable pH (7.2-7.4). The pH of real soap is outside that range and will cause some burning if it gets in the eyes.
Tear-free “soaps” don’t actually include soap at all, but this isn’t necessarily a great thing. They contain synthetic surfactants that may be carcinogens, endocrine disruptors, and allergens.
My soap strategy: do my best to avoid contact with the eyes and if it happens, rinse with clear water. So far we rarely have any problems.
No Time for DIY?
I love making my own products, but I don’t always have time these days either! Thankfully, companies have come a long way in the last 10 years. This store-bought bubble bath is rated as a top safer choice by the EWG (score of 1). If you try it please let me know what you think in the comments!

So disappointed. Not a bubble ?
hi, like you, i’m very cautious about using essential oils around my little one. i was wondering if i can add the herbs instead of the EO directly into the bath instead (using a tea bag)? e.g., lavender for sleep, thyme / elder flower for cough / fevers etc?
Absolutely. I’ve done that too. Although I find it works better when I brew as a strong tea and pour into the bath since typically more heat is needed than the temperature of the bath water.
Kathy, as near as I can tell, the reason people recommend liquid castile soap for this is that they have experience with the lather it makes with a small amount of even hard water, and so they think the bubbles will “scale up” in a bathtubful the same way they would with bubble bath, dishwashing liquid, or liquid “soaps” that are actually soapless. With such foaming products and detergents, you don’t have to add a proportional amount into hard water to make the same suds you’d get in a small amount of water in a large amount, but with soap you do. If you think about the ratio of a bathtubful of water to the amount of water on your hands or a sponge when you lather it with soap, you see that it might take a huge amount of soap for a bubble bath if your water’s hard. (Ask any engineer for stories about scale-up and how far off quantitative predictions can be for scaling up!)
And then they pass along the recipe without trying it, or they have soft water and get adequate results and think it’ll be like that for everybody.
Another thing is that when they recoil from the preservatives listed on the bubble bath label, they don’t stop to think about the preservatives in the liquid castile soap, because the rules for actual soap products like that don’t require them to be listed. My understanding is that the commonest preservatives used for liquid soap — as in the Dr. Bronner’s products prepared for them by Stahl Soap Co. — are formaldehyde or formaldehyde donors.
And finally, they think that because it’s soap it’s milder to skin. But if you use enough to make the entire bath sudsy, it’s as grease-cutting as dish or laundry water, and then you’re sitting in it for the entire bath, rather than just washing with soap and quickly rinsing. With bubble bath, you typically just use enough to make suds that float on top of the water, and don’t make the whole bath into a strong enough detergent solution to be just that — detergent (i.e. “cleaning”). There have been bubble baths that claimed to soak you clean, but in the concentrations you’d use I doubt they did significantly better at that than plain water.
Really wish I had read the comments before buying the ingredients and trying. No bubbles, just murky grey water.
This recipe didn’t produce one bubble, but the water was very murky (milky white). What did I do wrong?
I wish I had read these comments before making this recipe in my hard water city! Wellness Mama, perhaps adding a warning to the recipe would help others not make the same mistake.
So disappointing. Not a bubble and the ingredients were very expensive.
Every recipe I’ve ever included pure Castile soap in has been a massive flop. No bubbles and in this case it made gray water. On its own, Castile soap leaves an oily residue on dishes if used as dish soap and once again — no bubbles. Why does everyone recommend it?
Hi
I made this and I can’t get it to bubble at all. Help, what did I do wrong?
Thanks Kristen
Read all the comments and you’ll see my explanation.
Here’s from https://www.newspapers.com/newspage/59175086/ , one of a series of newspaper ads in the fall of 1939 for Lux (soap) flakes in areas of moderately hard water:
“Use your regular toilet soap for your bath, of course, but, in addition, just sprinkle the gentle Lux flakes in the water. The speedy Lux bubbles soften the water; Your bath feels extra soothing, extra cleansing. And at the end … no hard scrubbing to get rid of nasty black bathtub ring! Just a swish and your tub is clean. What joy to cut down on scrubbing on bathtub backaches! How much daintier your bath seems, too! The amount of Lux needed varies according to the hardness of the water. For water of average hardness, use about 5 tablespoons or a handful of Lux. For harder water, use more.”
Some of the ads made more to do of the bubbles as an attraction for children to bathe, but bathtub ring prevention was the chief sell. But as I wrote in an earlier comment, the result of using that much soap is a fairly grease-cuttiing bath you might not want to soak in, and would probably want a shower to rinse from. You CAN use soap (castile or otherwise) to make a bath of suds even in hardest water, if you use ENOUGH soap, but that could turn out to be an enormous amount.
Glycerine has little or no effect maintaining suds in a bath like that. Glycerine is useful in more concentrated solutions used for discrete bubble BLOWING, which is probably how it found its way into the recipe posted here.
