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.

    Thanks for posting this recipe! I’m dying to give it a try but I had a question- the recipe calls for 1/2 C + 1 tsp beeswax. I’m assuming that’s referring to pastilles, since that’s what the link brings me to BUT… I just bought solid wax bricks and want to know how much to use. What does the 1/2 C + 1 tsp of bees wax pastilles weigh so I can accurately follow the recipe? Thanks!

    I just made these bars, but put them in a silicone mold instead of an old deodorant container (they’re Christmas presents). Somehow, I think I might have not added as much wax as I should have (I sextupled the recipe!) as the bars are not as solid as I think they should be. Here’s my question: Can i simply remelt them all and add more wax? Or will the baking soda/arrow root powder respond oddly to reheating?

    Thanks for your help! These bars are going to be amazing!

      Yes you can re-melt them, you might have to add extra essential oils since the heat might kill the scent.

    Hey I just tried to make it and the results seem sticky and powdery at the same time to the touch. Is it normal. I did not put the probiotics.

    Hi, I live in Portugal and am trying to go ‘all natural’ on a very tight budget. I bought a cheap 4€ bottle of KTC 100% Pure Coconut Oil but have just realised that is says ‘flavourless oil’ on the back. So, it appears to be Refined and Bleached Coconut Oil made from Copra. Is this no good to make natural deodorant? Should I try getting a refund at the shop or is there a recipe for liquid hand soap recipe I could use it in? I cannot buy LYE in Portugal to make natural bar soap, nor arrowroot and it is extremely expensive to buy from amazon and have delivered.

      Hi Lisa, I live in Germany where arrowroot is also expensive and hard to find, so I substituted tapioca flour, which you can find at any Asian grocery store. Perhaps tapioca flour/starch is also used in Portuguese cooking? As for the coconut oil, I would try it anyway. It’s probably better to use it for making deodorant or lotion than to use it for cooking.

    hello
    I used Ban deodorant for many years ( it was the only Deodorant that didn’t make my armpit black) recentley I notice that my armpits were getting darker (company made some changes to the deodorant). I bought a mineral deodorant (chamomile and green tea) I also exfoliate my armpit with baking soda and lemon juice, but that irritated my skin.
    After some research I found your page 🙂 Today i made the deodorant bar recipe you think that this will help my armpit from getting dark.

    Just a thought- if the the alkalinity of baking soda is irritating, perhaps adding a small amount of vinegar with the baking soda could make the deodorant less irritating, without making it less effective? Obviously it will foam up, but at least the reaction will occur before it gets on your skin, and the alkalinity will be reduced? Or is the alkalinity important to baking soda’s deodorizing abilities?

    hi!

    i know this is an older thread but i was wondering if i could add bentonite clay to this? If so, how much should I use?

    thank you!

    1. Wellness Mama Avatar

      I have heard of people using clay in other recipes with great success, but I am not sure how you would incorporate it into the bar. Anyone else?

      1. Lindsay H Avatar

        I substituted about 1/2 the arrow root with bentonite and it worked fine as far as the consistency of the bar goes but I didn’t like that it turned the final product gray. It leaves a dark sitcky film on my skin that I don’t like and I don’t think it helped with sweat absorption. I’m going to go back to the original recipe next time I make a batch.

    Christine, just use a grater to grate the beeswax bar into shreds, then you can measure the 1/2 cup easily. Or Google some other recipes that use weight instead of volume measurements with similar ingredients.

      Thank u Lindsay for ur reply 🙂
      They are actually beewax sheets so that are a bit soft and waxy!
      Im afraid it would change the texture of the deoderant!

      What about the shea butter alternative (other than cocoa/ avocado/ mango etc… how can i replace it Do u know??

      1. Lindsay H Avatar
        Lindsay H

        I don’t know of a 1 for 1 substitute for the butter, you could try increasing the beeswax and coconut oils to make up for the shea but I don’t know what the consistency of the final product will be. I would experiment with small amounts to see the results before you waste a ton of ingredients.

    Dear Katie… does this deodorant glide well?
    I find that sometimes these type of deodorants do not glide smoothly and leave deodorant ,,crumbs,, behind? What is the secret to making the deodorant that glides well?
    How many deodorants or bars does one recipe make?
    thank u…

    Help! I accidentally added non-aluminum baking powder instead of baking soda… The deodorant is rising and foaming/fizzing. Is there anyway to fix this maybe by adding more of another ingredient or do I have to trash $50 worth of ingredients? Crossing my fingers! Thanks!

  12. Mona Avatar

    I love the deodorant but mine is very creamy and “soft”. It keeps it’s shape in the container but when I put it on it’s very creamy (not like regular stick) Is there something that I can add, or take away, to make it a little harder!

  13. jane Avatar

    I am NOT a doc or professional, but some bad reactions people had to this recipe might be due to poor quality Essential Oils they were using. in the recipe ….. use safe organic or wildcrafted oils ONLY – do not experiment, just use most safe oils like Lavender or Tea Tree.. quality of the ingredients matters!
    Essential oils are VERY concentrated substances- use with care!

    Can I use tapioca starch instead of arrow root? since tapioca can be replace with arrow root? want to make my deodorant, but I don’t want to use corn starch because of GMO.

    Your blog is awesome! I want to make a solid deodorant that stays solid yet contains magnesium oil. Have you come up with anything or have an idea of how to do this. I love your magnesium body butter but it too doesn’t get hard enough to work like a store bought solid.

    1. Wellness Mama Avatar

      Hm… I have not come up with anything like that yet. It seems to be one or the other. Magnesium oil is water-based, so it won’t mix with all the butters and wax 🙁
      You could try maybe using an emulsifying wax to get them to mix, maybe…

    I tried this recipe after experiencing much of the same results from other DIY deoderants which called for more baking soda (i.e. red rash). However, with one day of using this deoderant, the lymph nodes under both of my arms swelled painfully. It took days before it went away, and I can still feel lumps. Is this a reaction to the beeswax? Either way, I thought it was important to alert you. Have you studied the impact of combining these ingredients? And tested the pH balance? Thanks.
