How to Make a Probiotic Deodorant Bar (Easy Recipe)

homemade deodorant bar recipe

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 should also confess that sometimes I don’t make my own deodorant anymore since finding a pre-made option that uses the same ingredients and smells incredible! Check it out if you aren’t into the DIY version or don’t have the ingredients on hand.

What Are Deodorant Bars?

Deodorant bars are  is similar to homemade sunscreen bars but without the zinc oxide for sun protection and with baking soda and arrowroot added in for odor protection. These are slightly thicker than my original homemade deodorant recipe, which allows them to be used as a bar, or put into an empty deodorant container.

Since the homemade lotion bars, sunscreen bars, and deodorant bars all use many of the same ingredients, you can order these in bulk and save a lot of money on your family’s personal care products.

I also love Frugally Sustainable’s idea of adding probiotics to the recipe to help balance good bacteria and prevent odor, and I tried it with this recipe. If you have very sensitive skin or really struggle with odor, this might be a great option for you also!

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

Start with a Detox

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

Before You Start, You’ll Need

Deodorant Bar Ingredients

  • ½ cup coconut oil
  • ½ cup shea buttercocoa butter or mango butter (or a mix of all three equal to 1 part)
  • ½ cup + 1 tsp beeswax
  • 1 teaspoon Vitamin E oil – optional
  • 3 tablespoons baking soda (Omit this if you have sensitive skin and just use extra arrowroot or cornstarch)
  • 1/2 cup organic arrowroot powder
  • 2-3 capsules of high quality probiotics that don’t need to be refrigerated (optional)
  • Optional: Essential oils of choice – I used about 20 drops of lavender essential oil and also like citrus and frankincense

Deodorant Bar Instructions

  1. 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 type of projects and not even need to wash it out…
  2. Turn the burner on and bring water to a boil. Stir ingredients constantly until they are melted and smooth:
  3. 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.
  4. Gently stir by hand until all ingredients are incorporated.
  5. If you will be making these into bars, pour into muffin tins or other molds while still liquid. If you will be putting into an old deodorant container to use like stick deodorant, let the mixture harden for about 15-20 minutes at room temperature to harden and when it is about the consistency of peanut butter, use a spoon to scoop into the deodorant tube and pack down to fill. Then, leave the cap off overnight to completely harden before using.

Note: This recipe can be adjusted to make any quantity that you’d like by increasing the amount of ingredients used. This batch made enough deodorant for my husband and I for about 2-3 months. You could also cut the recipe in half if you want to make a smaller amount.


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 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 just due to the oil residue that is there for a few minutes right after it is applied. Try keeping it in the fridge so a smaller amount is transferred to skin or waiting approximately 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 also common in some skin types and if you have used conventional deodorant for a long time and have a build up of the chemicals from that deodorant in your skin. 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, which resolves the issue for most people.

Is this an antiperspirant?
No. Stopping the body’s ability to sweat is not a natural process and there is no way that I know of to accomplish this naturally. The good news is that you will sweat less and 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 and just using a very light natural deodorant.
