Beer, Soap & Other Questionable Decisions - Why There’s Beer in Your Soap—and Everything You Were Afraid to Ask About It

Wait… There’s Actual BEER in My Soap?!

So you bought a bar of beer soap.

Or maybe somebody gave you one because apparently nothing says “I care about you” quite like washing your ass with Budweiser.

And then you looked at the label.

Wait. There’s actually BEER in this thing?

Yes. Sometimes there really is.

Which immediately raises several perfectly reasonable questions:

-Am I going to smell like I spent the afternoon facedown on a sticky bar floor?

-Can beer actually do anything useful for my skin?

-Is beer soap just for men?

-What does it do to my skin’s pH?

-Is there alcohol left in it?

-Can alcohol somehow get into my body through my skin?

And because the internet has taught us never to underestimate a question:

-Could I get a DUI because I showered with Budweiser?

(Settle down, Officer. It’s soap.)

But those questions aren't actually as ridiculous as they sound. Beer has a surprisingly interesting chemistry, and brewers have spent centuries combining barley, hops and yeast for drinking purposes. Somewhere along the way, somebody apparently looked at a perfectly good beer and thought:

You know what? I should bathe with that.

So, today we're going to find out exactly what the hell the beer is doing in there.

First Things First: Why the Hell Would Anyone Put Beer in Soap?

Beer soap isn't simply regular soap that somebody waved over a six-pack.

Depending on the product, actual beer or brewing ingredients may be incorporated into the formulation. And once you get past the novelty factor, the idea isn't quite as ridiculous as it sounds.

Beer is made from ingredients such as malted grains, hops and yeast. Hops and other brewing materials contain a variety of plant compounds that have attracted scientific interest for potential cosmetic and skin-care applications.

That does not mean your beer soap is medicine. It doesn't mean Budweiser cures eczema, eliminates acne, reverses aging or grants you the complexion of a 22-year-old who drinks eight glasses of water every day.

We aren't making those claims.

What it does mean is that beer is more chemically interesting than “water that makes karaoke seem like a good idea.”

There are legitimate reasons formulators have experimented with beer and brewing by-products in cosmetics and skin-care products.

And then, of course, there's the other reason:

It's beer soap. That's funny.

Yes, Angus.  Sometimes commerce really is that simple.

So What's Actually in Beer That Makes Anyone Think, “Yeah, Let's Rub That on Our Skin?”

Beer is more than alcohol, carbonation and questionable late-night decision-making.

Depending on how it's brewed, it contains compounds contributed by hops, malted grains and yeast. Hops contain plant compounds including polyphenols and flavonoids that researchers have studied for antioxidant, antimicrobial and anti-inflammatory activity. Brewing grains and yeast also contain compounds that have attracted interest for possible cosmetic applications.

Scientists have even been looking at ways to turn brewing by-products—things breweries would otherwise have to discard—into useful ingredients for cosmetics and skin-care formulations.

That's actually pretty damn cool.

But here's where Mrs. Bones puts on her tiny imaginary lab coat:

An ingredient having interesting properties in a laboratory does not automatically mean a bar of soap containing that ingredient will produce the same effect on your skin.

Soap is a finished formulation. Ingredients interact. Concentrations matter. Processing matters. And something that gets rinsed down the drain thirty seconds later is very different from something designed to remain on your skin.

So yes, there is actual science behind researchers being interested in beer and brewing ingredients for skin care.  But, no, washing your face with Budweiser will not make you immortal.

Please stop making us clarify these things.

Does Beer Soap Actually Do Anything Good for Your Skin?

Potentially—but this is where we're going to separate interesting science from marketing bullshit.

Research has examined compounds associated with hops and other brewing materials for antioxidant and other biological properties. There's scientific interest in finding useful cosmetic applications for materials that otherwise become brewing by-products.

That's interesting.  It is not, however, the same as proving that every commercial bar labeled “beer soap” produces a particular skin benefit.

The finished soap matters.  Its complete ingredient list matters.  Your skin matters.  How frequently you use it matters.  And whether the manufacturer actually put beer in the thing—or simply made something that smells vaguely like a tavern—matters.

So when somebody promises that beer soap is going to perform miracles because “hops are good for your skin,” Mrs. Bones would like everybody to put down the marketing copy and back away slowly.

Interesting ingredient? Yes.

Magical dermatological intervention? No.

Is Beer Soap for Men or Women?

Beer soap has been marketed heavily toward men, particularly by brands that package their products somewhere on the aesthetic spectrum between lumberjack and I own seventeen socket wrenches.

That doesn't make the soap male.  Women can use beer soap.  Men can use beer soap.  Nonbinary people can use beer soap.  Your skin does not check the gender section of your driver's license before allowing you to lather.

There are average biological differences between male and female skin, but those differences don't turn beer soap into a sex-specific cleansing product.

The much more useful questions are:

What's actually in this particular soap?

And:

Does my skin tolerate it?

If you like the ingredients, fragrance and way your skin feels after using it, congratulations.  You have successfully overcome gendered soap marketing.

But What About My Skin's pH?

Now we're getting somewhere.

Healthy skin has what is often called an acid mantle—a mildly acidic surface environment that helps support normal barrier function.

Traditional soaps are generally more alkaline. Research comparing conventional soap with synthetic detergent—or “syndet”—cleansers has found that ordinary soap can temporarily increase skin pH and can be more irritating under some testing conditions.

But here's the important part:  Putting beer into soap doesn't magically make that issue disappear.

You need to consider the finished formulation rather than assuming that because beer itself has a certain chemistry, a finished beer soap must behave the same way.

If your skin is particularly dry, sensitive, irritated or prone to dermatitis, the safest question isn't really: “Is beer good for skin?”  It's: “Is this particular cleanser good for MY skin?”

Your epidermis is allowed to have standards.

Am I Going to Smell Like Beer?

This may be the most important question in the entire article.

Because there is a substantial difference between:  “I washed with beer soap.” and “I smell like somebody knocked over a pitcher of Miller Lite on me at 1:47 a.m.”

Fortunately, those are not the same thing.

The scent of the finished soap depends on its complete formulation and added fragrance. A product can contain brewing ingredients without leaving you smelling like an open bottle of beer.  Likewise, something marketed with a beer-inspired scent doesn't necessarily tell you how much—or even whether—actual beer is present.

In other words:  Beer soap and beer-scented soap aren't automatically the same thing.

Read the label.  Mrs. Bones is very big on reading labels.  It's how we end up writing articles like this.

Wait—Is There Still Alcohol in Beer Soap?

Ah. Now that's a good question.

And unfortunately, the answer is the researcher's favorite: It depends.

“Made with beer” does not automatically tell you how much ethanol—if any—remains in the finished bar.

Soapmakers can handle beer differently during production, formulations vary, alcohol is volatile, and manufacturing involves conditions that can change what remains in the finished product. Without information or testing from the manufacturer, we shouldn't look at the word BEER on a package and pretend we know the finished product's alcohol concentration.

What we can say is that beer being used as an ingredient and a finished bar of soap being an alcoholic beverage are two very different things.

Which naturally brings us to:  Can this damn thing get me drunk?

Can Beer Soap Get Me Drunk?

Under normal use?  No.  

Please do not lick the soap to double-check.

There is a legitimate scientific question buried underneath the ridiculous one, though: alcohol can cross human skin under certain exposure conditions. Scientists have actually studied dermal ethanol absorption.

But exposure matters enormously.

One human study examining an alcohol-based topical spray found no detectable alcohol in the blood samples of the 16 volunteers under the conditions tested. Other experimental research shows that ethanol can penetrate skin under particular conditions, especially with concentrated ethanol and prolonged exposure.

That's precisely why we shouldn't say, “Alcohol can never pass through skin.”  Science rarely appreciates the word never.

But washing yourself with a rinse-off beer soap is wildly different from deliberately exposing skin to nearly pure ethanol for hours.

No, Jonathan.  Your shower is not a keg stand.

Could I Fail a Breathalyzer Because I Used Beer Soap?

This is where we need to distinguish a funny question from an actual legal claim.

A breathalyzer measures alcohol associated with breath—not whether your elbow recently encountered Budweiser-branded soap.

There can be circumstances where alcohol-containing substances in or around the mouth temporarily affect breath testing, which is one reason proper testing procedures matter.  But that's a fundamentally different situation from washing your body with a bar of beer soap.  There is no reasonable basis for expecting ordinary external use of a rinse-off beer soap to create an intoxicating blood-alcohol concentration.

Which brings us to the question somebody, somewhere, is absolutely going to Google:

Can I Get a DUI From Showering With Beer Soap?

If you've consumed enough alcohol to be impaired, don't drive.

If you've merely washed your armpits with Budweiser soap? You’re probably good to go.  That's not what DUI laws are about.

We're also not going to promise what every police officer, breath-testing instrument or legal system in every jurisdiction on Earth will ever do under every bizarre imaginable circumstance.

Hey, that's what lawyers are for.  But using beer soap normally isn't the same thing as drinking alcohol.

“But Officer, I swear it was the soap” should not need to become part of your evening.

Does Beer Soap Put Alcohol Into My System?

This is really the more scientifically useful version of the DUI question.  As we just discussed, ethanol is capable of penetrating skin under certain experimental conditions. But concentration, exposure time, the area of skin exposed, evaporation and formulation all matter.

Beer soap is a rinse-off cleansing product, not a glass of beer being introduced into your digestive system.

So while we're not going to make the scientifically sloppy statement that skin is an impenetrable force field through which ethanol can never pass, normal beer-soap use isn't equivalent to consuming beer.

You are washing.  Not drinking.  Please maintain that distinction.

And Now We Have to Talk About Your (or Your Wife’s) Vajayjay.

We all knew we'd get here eventually.

Can Beer Soap Give Me a Yeast Infection?

Not necessarily because your vagina somehow discovered you've introduced Budweiser and decides it's time to start brewing its own batch.

But this is one place where we actually have to put the jokes aside for approximately seventeen seconds.

The vagina naturally contains microorganisms—including yeast—and maintains a slightly acidic environment that helps keep those organisms in balance. Disrupting that normal environment can contribute to vaginal problems.

So: No, absolutely do not put beer soap inside your vagina.  Actually, don't put ordinary soap inside your vagina either.

The American College of Obstetricians and Gynecologists (ACOG) specifically advises against douching and vaginal hygiene products, and notes that the vagina cleans itself.

Now, the vulva is the external anatomy, and that's different. Guidance varies somewhat depending upon irritation and individual sensitivity: ACOG's general vulvovaginal-health guidance says the vulva may be washed with plain fragrance-free soap and rinsed, while its guidance for irritated vulvar skin recommends water alone and avoiding perfumed products.

So there is absolutely nothing wrong with your vagina participating in happy hour.  It just doesn't need the beer.

And while there isn't good reason to say that beer itself in a bar of soap automatically causes a yeast infection, your Budweiser bar still doesn't need an invitation to the downstairs pub.  Use products appropriate for sensitive intimate skin and keep ordinary soap out of the vagina.

As for the rest?

“Here, honey, hold my beer” has a WHOLE different meaning at this particular happy hour.

We have now officially researched this.  You're welcome.

What If I Don't Drink Alcohol?

This one's more personal than chemical.  Using a product containing beer isn't the same physiological activity as drinking an alcoholic beverage.

But people avoid alcohol for all sorts of reasons—religious beliefs, recovery, personal preference, medical reasons or simply because they don't like it.  And for somebody in recovery, beer branding or fragrance could potentially be unwelcome even if the product isn't intoxicating.

That's not something Mrs. Bones gets to decide for another person.

If having Budweiser in your shower bothers you, there are approximately nine billion other soaps available.  Pick one that doesn't.  Bathing should not require an existential crisis.

What About Gluten, Barley or Allergies?

This deserves more nuance than “beer has barley, therefore beer soap has gluten, therefore panic.”

Celiac disease is primarily triggered when gluten is ingested. But that doesn't mean every person with every grain-related condition should automatically smear a barley-containing cosmetic all over themselves.

Contact allergies and skin sensitivities are separate issues.  And different beer soaps contain different ingredients.  If you have a diagnosed wheat, barley or other ingredient allergy—or you've previously reacted to topical products containing those ingredients—read the actual label and follow the advice you've received from your medical professional.

Never assume every product called “beer soap” contains exactly the same thing - because it doesn't.

So… Is Beer Soap Actually Worth Using?

Here's the wonderfully boring answer after all of that:  Beer soap can be a perfectly reasonable soap if you like the formulation and your skin likes it.

Beer and brewing ingredients make for an interesting formulation story. There's legitimate scientific interest in compounds found in hops and brewing materials.  But you don't need to believe that beer soap possesses mystical powers to enjoy it.  Maybe you like the scent.  Maybe you like the lather.  Maybe you like a big substantial bar.  Maybe you bought it because it says Budweiser on the package and you thought it was hilarious.  All of these are perfectly acceptable reasons.

Not every object in your bathroom needs to alter the trajectory of human civilization.  Sometimes soap can just be good soap with beer in it.

But Apparently Putting Beer in the Soap Wasn't Enough.

While researching all of this, we discovered that beer hasn't been confined to the shower.  Because humanity is never satisfied, at some point somebody at Duke Cannon looked at a bottle of Budweiser, looked at a man's facial hair and thought:

You know where that beer needs to be? In his beard.

And yes, Mrs. Bones actually has this Great American Beard Oil Made With Budweiser, which, according to the product information, is made with natural and organic oils and a touch of Budweiser beer.

Which naturally creates another question absolutely nobody at Mrs. Bones intended to research today:

If I Put Beer in My Beard, Can I Fail a Hair Follicle Test?

Oh, for fuck's sake.  Fine.

First, the thing everybody calls a “hair follicle test” generally tests the hair, not the follicle itself. Nobody is yanking tiny follicles out of your chin and asking them where they were at on Friday night.

And putting a product containing beer on your beard is not the same thing as drinking beer.

But—and this is where our stupid question becomes annoyingly legitimate—hair testing can be affected by external contamination and cosmetic products, which is something forensic toxicologists actually have to consider.

Alcohol-related hair testing can look for specific biomarkers rather than simply detecting whether a molecule of ethanol has ever touched your hair. Researchers have also studied how cosmetic treatment and external exposure can complicate interpretation of those tests.

So no, we are not going to tell you that rubbing Budweiser beard oil into your face means you've consumed alcohol.  We're also not going to promise that no grooming product could ever interfere with any conceivable forensic hair test, because apparently this article has standards now.

If you're undergoing employment, probation, forensic, medical or other consequential hair testing, tell the testing professional exactly what you've been putting on your hair or beard.

And, whatever you do, do not tell your probation officer, “Mrs. Bones said I'd be fine.”

Mrs. Bones has enough problems.

Okay, But Does the Beer Soap at Mrs. Bones Actually Have Beer in It?

YES. We checked.

Because after writing several thousand words about beer soap, it would be mildly embarrassing to discover that ours was just regular soap wearing a tiny beer costume.

The Duke Cannon Great American Beer Soap made with Budweiser currently in the Cupboard lists Budweiser® Beer right in the ingredients.

And despite containing actual Budweiser, it's not supposed to leave you smelling like you spent the night sleeping underneath the bar. The Budweiser version has a warm cedarwood fragrance.

Our Old Milwaukee beer soap isn't bluffing either. Its published ingredient list includes beer, and it was made using Old Milwaukee lager.

So when Mrs. Bones says we're selling beer soap, we're not speaking metaphorically.

There is actual damn beer in the soap.

Which, after everything you've just read, probably raises fewer questions than it did twenty minutes ago.

Probably.

Fine. Now I Want to Wash Myself With Beer.

We knew you'd come around.

And as luck would have it, Mrs. Bones Curio Cupboard currently has enough Duke Cannon products hanging around the Cupboard to make some questionable bathing decisions of your very own.

Start with the obvious: Great American Beer Soap Made With Budweiser. This is a whopping 10-ounce bar, and yes—the whole reason we've dragged you this far down the beer-soap rabbit hole is because this one is actually made with Budweiser.

Great American Beer Soap – Made With Budweiser

Prefer your questionable decisions a little more old-school? There's also the Duke Cannon Big Ass Beer Soap made with Old Milwaukee Beer, another 10-ounce monster of a bar, this time with a rugged sandalwood scent.

Duke Cannon Big Ass Beer Soap – Old Milwaukee Beer

And apparently beer wasn't enough, because somebody eventually asked:

“What if we put whiskey in the soap?”

Of course they did.

The Big American Bourbon Soap is made with Buffalo Trace Kentucky whiskey. It's not technically beer soap, but after everything we've been through together, excluding the whiskey soap now would just seem rude.

Duke Cannon Big American Bourbon Soap with Buffalo Trace

Then there's Leaf and Leather, a giant 10-ounce Duke Cannon bar for anyone who would like their soap enormous but would prefer that nobody pour an alcoholic beverage into it.

Duke Cannon Big Ass Brick of Soap – Leaf and Leather

But wait.

We can also put the beer in your beard.

The Great American Beard Oil Made With Budweiser is a 3-ounce beard oil made with natural and organic oils and a touch of Budweiser beer, because apparently your facial hair also deserves happy hour.

And because we are committed to giving your beard choices, there's also Duke Cannon's Big Bourbon Beard Oil.

Duke Cannon's Big Bourbon Beard Oil

And if you'd rather keep the booze out of your beard entirely, Mrs. Bones also has a custom-curated Beard Grooming Gift Set. We put each set together ourselves with everything you need for a proper beard-care routine, arranged in a wooden bowl and ready to gift.

No Budweiser. No bourbon. Just everything your beard needs in one damn bowl.

And these aren't just sitting around looking pretty—we sold all but one of them at a pop-up last weekend. One purchaser told me, “These nice of products are difficult to find.”

Beard Grooming Gift Set in Wooden Bowl | Gift Ready Men’s Kit – Mrs. Bones Curio Cupboard

So there you have it.

Beer soap. Bourbon soap. Beer beard oil. Bourbon beard oil. And one enormous bar of perfectly sober Leaf and Leather standing in the corner wondering how the hell it got invited to this party.

They're useful. They're funny. They make excellent gifts. And frankly?

Mrs. Bones would very much like some of them to start hanging around your house instead.

Unlike an actual six-pack:  No ID is required. No designated driver is required. And, mercifully, no hangover is required.

Just remember what we've learned today:  Wash your body. Just don't drink the soap.  And, for the love of all that's holy, keep it out of the downstairs pub.

And remember, should someone ever yell— “HERE, HOLD MY BEER!”—please establish whether they're talking about the Budweiser or the soap before agreeing to anything.

Normal was never an option.

A Note From the Cupboard

Mrs. Bones Curiosity Guides are written to answer the strange questions that send all of us down internet rabbit holes. Health information in this guide is educational and isn't individualized medical advice. If a product causes burning, itching, rash or other irritation, stop using it; persistent or significant symptoms deserve a conversation with a qualified healthcare professional.

Where the Hell Did Mrs. Bones Get All This Information?

We know. We know.

You came here to find out whether washing your ass with Budweiser could get you arrested and somehow ended up learning about skin-barrier chemistry, ethanol absorption, vaginal pH and forensic hair testing.

The internet is a magical place.

Fortunately, Mrs. Bones doesn't just make this shit up.  For anyone who has made it this far down the rabbit hole and would now like to check our homework, here are some of the places we researched:

Beer, Hops & Why Scientists Are Putting Brewery Stuff in Cosmetics

Cosmetic Efficacy and Sustainability of Beer and Brewing By-Products in Skin Care: A Formulation-Driven In Vitro and In Vivo Evaluation

Can Alcohol Actually Get Through Your Skin?

Fate of Ethanol Topically Applied to Skin
Yes, scientists have studied this too. The research examined evaporation and skin penetration of ethanol as well as blood alcohol measurements after simulated use of an alcohol-based topical spray. In the human portion, none of the blood samples from the 16 volunteers contained detectable alcohol under the conditions tested.
Read the study on PubMed

Again: an alcohol-based spray isn't beer soap. We used this research to explain why “alcohol can never cross skin” would be scientifically sloppy, not to pretend somebody conducted the Great Budweiser Shower Experiment.

The Beard-Oil Question That Had Absolutely No Business Becoming Legitimate Science

Positive EtG Findings in Hair as a Result of a Cosmetic Treatment
This is the one that made us say, “Oh, for fuck's sake. The stupid question is actually interesting.”

Researchers documented an unusual case in which an alcohol-containing hair lotion itself contained ethyl glucuronide (EtG)—a biomarker used in alcohol-related hair testing—and produced misleading EtG findings in treated hair. The researchers emphasized that this situation was exceptionally unusual, but it demonstrates why external contamination and cosmetic products can matter when interpreting hair-test results.
Read the forensic toxicology study on PubMed

Identification and Analysis of Damaged or Porous Hair

Additional forensic-toxicology research discussing cosmetic hair treatment, external contamination and the importance of laboratories recognizing the condition and treatment of hair when interpreting results.

So once again:  Putting Budweiser beard oil on your face is not the same thing as drinking Budweiser.

But if somebody is conducting a consequential forensic hair test, tell them what you've been putting on your damn hair.

Yes, We Actually Researched the Vajayjay Part Too

A Small but Important Disclaimer

Science changes. Product formulations change. Manufacturers change ingredients. And your skin may react differently from somebody else's skin.

Sources were reviewed for this guide at the time of publication. When we're discussing a specific product, the current product label wins.

If you've got a medical condition, allergy or persistent skin or vaginal symptoms, this is the point where Mrs. Bones cheerfully hands the problem over to an actual qualified healthcare professional.

No, Brenda. We sell curiosities. We are not your gynecologist.
