Natural deodorant has gotten really popular in recent years, but a lot of people have mixed results. This probiotic deodorant recipe doesn’t just mask the odor, it attacks it at the source!

One of the most asked questions on my popular homemade deodorant post is: “Can I put this in a plastic deodorant container for easy application?”

And the answer is- absolutely yes! But it will work better if you make a couple of tweaks! I’ve played with my original recipes to create several different variations, including this probiotic deodorant.

Why Do Armpits Stink?

Before we go into fixing the problem, it helps to know why it’s there in the first place. Conventional deodorants work by covering up body odor with fragrances. They also clog pores with aluminum to prevent sweating. But why do we get stinky to begin with?

B.O. 101

Like the rest of our skin, underarms have a natural microbiome complete with bacteria. When things are unbalanced and the bad bacteria is in charge it causes stanky pits. This odor-causing bacteria, not sweat itself, is to blame. According to Popular Science:

“Sweat by itself doesn’t actually smell. It contains long chains of molecules that are too heavy to vaporize and reach your nostrils. But the bacteria in your pits break down these big molecules into smaller molecules that fly off, and depending on what kind of bacteria are living on you, those volatiles can smell pretty foul.”

What we eat plays a big role in our underarm bacteria, as do healthy (or unhealthy) lifestyle choices. Genetics can also play a part. Our bodies detox through the sweat in our armpits. If there are more toxins released into our system, then naturally there’s more stinky sweat.

Want to Buy it?

I should confess that sometimes I don’t make my own deodorant anymore. The company I co-founded, Wellnesse, now offers a mineral deodorant. Check it out if you aren’t into the DIY version or don’t have the ingredients on hand.

It’s cruelty-free, phthalate and paraben free, and of course aluminum-free. It also features soothing ingredients like aloe, and cocos nucifera (coconut oil), without harsh preservatives.

Why Natural Deodorant Doesn’t Work

Many people who make the switch to natural deodorant are disappointed with the results at first. They may notice an increase in underarm wetness or even smell. Then there’s the infamous baking soda rash. But what’s really going on here?

If our skin is used to having blocked pores preventing it from sweating, then there’s a backlog of toxins. That area is also rich in lymphatic tissue which helps us eliminate waste products. Using natural deodorant helps to support these natural processes, but it takes time to balance things out.

Start with a Detox

If you’re new to natural deodorant, I’ve found an armpit detox, done once a week or so, greatly speeds up the adjustment period. It also makes the deodorant more effective more quickly. Here’s how to detox your pits.

Since switching to a natural deodorant I’ve gradually noticed less underarm odor and sweating.

Probiotic Deodorant Bar

That said, how can probiotics help us have healthier (less stinky!) pits? Probiotic deodorant works by adding more of the good bacteria to the skin microbiome. Over time this helps push out more of the bad bacteria strains that cause odor.

Some of the healthy bacterial strains found in armpits include Staphylococcus epidermidis and Propionibacterium acnes. Outside of test tubes meant for a lab, these strains are harder to source. Instead, most probiotic deodorants rely on strains normally found in the human gut, like lactobacillus supplements. While they’re still beneficial for skin, the effects may be more transient.

These nourishing probiotic deodorant bars are slightly thicker than my original homemade deodorant recipe in a jar. It also uses many of the same ingredients as my lotion bars and sunscreen bars. You can order the ingredients in bulk and save a lot of money on your family’s skincare products this way.

If you have sensitive skin or struggle with odor, this can be a great option! I did include some baking soda to help control odor. If you’re very sensitive you can replace it with more arrowroot for a baking soda free version.

Choose Your Scent

Essential oils naturally have antimicrobial properties that make them great for homemade deodorant. My favorite here are lavender, frankincenses and citrus essential oils. Here are a few more skin-safe options. You can also do an unscented version if desired.

Try making your own deodorant if you haven’t already. You’ll not only save money and avoid synthetic chemicals, but I’ve found the homemade versions work better too!

Probiotic Deodorant Recipe

This simple recipe helps fight underarm odor naturally, with healthy probiotics!
Prep Time5 minutes
Active Time30 minutes
Cooling Time8 hours
Total Time8 hours 35 minutes
Yield: 5 deodorant tubes
Author: Katie Wells

Materials

Instructions

  • Combine coconut oil, shea (or other) butter, and beeswax in a double boiler, or a glass bowl over a smaller saucepan with 1 inch of water in it. Combine in a quart size glass mason jar with a lid instead and place this in a small saucepan of water until melted. This will save your bowl and you can just designate this jar for these types of projects and not even need to wash it out…
  • Turn the burner on and bring the water to a low boil. Stir ingredients occasionally until they're melted and smooth.
  • Remove from heat and add the vitamin E oil, baking soda, arrowroot powder, probiotics, and essential oils. Make sure the mixture is not hot to the touch (warm is ok) so that the heat doesn’t kill the probiotics. If you're using the brand I've linked above, they're fine at higher temperatures.
  • Gently stir by hand until all ingredients are incorporated.
  • Let cool for about 15 minutes, until the mixture is slightly thickened, but still a pourable consistency.
  • Pour the deodorant mixture into new or repurposed and cleaned deodorant containers. Let dry overnight to fully harden.

Notes

  • This recipe can be adjusted to make any quantity that you’d like by increasing the amount of ingredients used.
  • Shea butter yields a softer deodorant consistency, while cocoa butter is much firmer. You can also use a blend of shea butter, mango butter, and/or cocoa butter.  

Deodorant FAQs

Why is mine taking so long to harden?

This is common when using the baking soda. Try putting it in the fridge for a few hours to harden. I actually like keeping mine in the fridge all the time and applying it while I’m making breakfast since it keeps it really cool and refreshing.

It seems to be leaving stains on my shirt- what do I do?

This is likely due to the oil residue that’s there for a few minutes right after applying. Try keeping it in the fridge so a smaller amount is transferred to the skin. Or wait about 5 minutes after applying before putting a shirt on.

Help! I have a horrible rash after a few days/weeks/months of using this.

This is common in some skin types and if you’ve used conventional deodorant for a long time. I’ve found that doing an armpit detox once a week makes a huge difference. You can also try omitting the baking soda from the recipe. This resolves the issue for most people.

Is this an antiperspirant?

No. Stopping the body’s ability to sweat is not a natural process. There’s no way I know of to do this naturally. The good news is that you’ll sweat less as your body adjusts to a natural deodorant and it won’t be needed anymore. Again, the armpit detox can help speed that up. I went from using clinical strength deodorant to not needing an antiperspirant at all!

I’m allergic to coconut oil

If you have a coconut allergy then you can use 2 Tablespoons of a liquid oil instead of the 1/4 cup of coconut oil. Olive oil, grapeseed, and sweet almond oil are several different options.

    Hi! I was so excited to try this recipe! And I made it and it smells amazing… but just wondering… what exactly is the purpose of the flour in the recipe? I understand the baking soda helps to remove any bad odors, but is the flour just a filler to thicken up the bar? We are sensitive to both arrowroot and corn starch/flour so I used tapioca flour instead and so far it seems to be ok.

    Thanks so much for sharing all your knowledge! Much appreciated!

    I LOVE this recipe! I made half the batch with lavender EO for me and half with tea tree for my husband. It glides on really nicely and feels very moisturizing. Its a keeper!

  3. Frankie Avatar

    I tried rubbing baking soda once on my underarm to help with smell but it wound up burning and turning red, should I leave the baking soda in when trying this recipe, or not?

  4. Alanna Avatar

    I’m very excited to make this. Is it comparable to any deodorants you can buy in stores? Pure Pitz is the only natural deodorant I have ever used that worked.

    I just made my deodorant bars two days age and left out the baking soda and just used more arrowroot as per instructions. It is fantastic! I filled 5 old deodorant containers which cost average of $7 per from local health food store. This is much better in terms of performance and very cost effective. This time I used lavender essential oil but will have to make something more “manly” smelling although my wife loves using this. I haven’t used a better product than this, thanks for the recipe.

        I used tapioca starch instead of arrowroot (cheaper and easier to find where I live), and it worked great. My bars hardened nicely, and I haven’t had any sort of adverse reaction to the mix.

  6. Jen Avatar

    I just made but my ingredients won’t combine as it hardens. What could I have done wrong and is there an easy way to fix without killing the probiotics?

    I used coconut butter instead of cocoa butter. Is this a good substitute? I actually did it accidentally. I read the recipe wrong. I didn’t have bees wax either.

    What amount of zinc oxide should be added? I’m happy to hear of a solution because I am one of the people with the red burning armpits. I left out the baking soda and it didn’t work. Does the zinc oxide come in a powder form? Thanks

    1. Pam Avatar

      Zinc oxide does come in powder form. Mine is from New Directions Aromatics but it’s widely available online; you can even try ebay or Amazon.
      If you’re making 4 oz. of deodorant, about 1-1/4 tablespoon (0.6 oz) zinc oxide should do it.

    I’ve made all my deodorants and skin care products for years. The issue with red tender underarm which so many people report after trying this recipe is due to the high alkalinity of the baking soda. Please don’t use baking soda! One reader suggested using zinc oxide and I highly recommend substituting this in place of the baking soda. It’s antimicrobial and gentle … resolves painful diaper rash, safe to use on infants. Stops bacteria that cause underarm odor, works great with coconut oil.
    If you cant tolerate coconut oil, use castor oil (also antimicrobial) but blend it with another oil because castor oil can be drying to skin.
    I believe the underarm clothes staining is from the oils in this recipe. I recommend following deodorant application with a scented powder, which absorbs excess oil and adds a luxurious touch. You can make your own with arrowroot or tapioca powder scented with a few drops of an antimicrobial essential oil … myrrh is great. Your clothing will be protected and you’ll smell exotically beautiful all day.
    BTW, powder or flour works for getting oil stains, grease splatters, etc out of clothing in general. Just heap the powder, flour, etc on your stain … you can rub it in and let it sit overnight. The powder will absorb the grease and you can launder as usual.
    As for laundry itself … try minerals instead of expensive detergents. 20 Mule Team Borax is all natural, eco-safe and lifts out dirt amazingly … couple this with sodium bicarb (Arm & Hamner Super Washing Powder aka baking soda but sold much cheaper/not food grade as Super Washing Powder) — boosts detergent. I use both of these with a grated bar of soap (Fels Naptha is formulated for laundry). Environment- friendly, easy on your wallet, clothes come out soft, clean and smelling great!

    I plan on making this recipe with a class soon. I need clarification on the amount of beeswax. Is this amount stated for melted beeswax? beeswax pellets? shaved? 1/2 cup of beeswax looks very different depending on the form of the wax… thanks for the help!

    I was wondering how much this recipe makes? I have used coconut oil for years but its not really working after my second bub so want to try this out but not sure how many deodorant sticks I will need and what size. Many thanks. x

      Hi!
      I just made this recipe a week ago, I followed the amounts in the recipe exactly and it made 4 tubes of deodorant. They are the 2.65 oz tubes you can by from Amazon, pretty much the same size as a full size deodorant you can buy in the store.

    Been using this for the past week and I have to say this is very promising.
    If it keeps up. I am using this forever! Simply love it!!
    I used only 1 Tbsp of baking soda and arrowroot powder for the rest upon reading other commenters’ sensitivity issues and this is working for me.
    Thank you!

    I made this last week and have been using it ever since. I had a slight burning sensation the first couple of times I used it, but that was it. No rash etc. I did not use the probiotic, and I substituted tapioca flour for arrowroot, as that’s pretty hard to find where I live. As far as I can tell, that worked fine. Once comment to those wanting to fill this into old deodorant containers – I would do this while the mixture is still liquid (let it cool a bit). Much easier and less messy.

    I love this! I made it without the vitamin E, the beeswax and the probiotics, and it works great! I used cocoa butter with coconut oil. My only issue is that it turns to liquid when it hits my pits. I may also have used more coconut oil than cocoa butter so the heat of my skin melts it quickly. Would the beeswax help that from happening? What would adding sea salt do?

    Thank you for sharing! I made this for myself and store it in a glass container in a dark place. There appears to be tiny white splotches throughout. It doesn’t smell funny and it works great. Should I toss it to be safe or could this be normal for my home conditions? The elevation is 4,000 feet where I live and it is currently 20 degrees. I appreciate your help and wonderful recipes!

    I make my own liquid deodorant. I think it’s supposed to be a thick cream, but not in hawaii 🙂 here, coconut oil is usually liquid. Anyway, I’ve begun to develop a rash and will make a new batch sans baking soda. I’m going to make this recipe for my son. Thank you!

    I made this today. I love the bars!! I used a mini bundt cake silicone mold and they came out beautiful!! Wish I could post a pic!

    Baking soda fried my pits in a serious way, so I quickly tossed it and switched to a coconut/shea/tea tree oil concoction that I rub on daily, with pretty fair luck (I have beastly BO so it sometimes fails me… but I am unwilling to EVER go back to conventional deo… anyway). I still missed the convenience of stick deo, so I bought some arrowroot powder and beeswax and tried again, adding extra arrowroot as the recipe suggests. I tried it the next morning and to my dismay, it is incredibly tacky, like it is gluing my skin together. I don’t get how or why it is like this. Too much arrowroot? Because the chap stick I made right after was made with all the same ingredients in all the same proportions EXCEPT the arrowroot (coconut, shea, beeswax, vitamin E oil). It seems odd though. I want this to work so badly >.<"
