If baking soda can subdue the odor of a cat litter box, imagine what it can do under your arms. Yep. All by itself, or if you want, you can add talc or other powder to it at a ratio or half and half. Put it in a tin and keep it in the bathroom.

After you shower, pat dry your underarms and apply the powder with a dry washcloth or piece of a dishrag. The only time this is not a good plan is when you are wearing something sleeveless.

A deodorant crystal from the health food store is another option for natural deodorant. I have one and it works pretty well, unless you sweat a lot.

Please do not use talc! If you mean baby powder, most is made by using cornstarch - check labels. Old fashioned formulas, even Johnson's, contain talc. Talc is breathed into the lungs and very harmful.


Straight baking soda will burn your underarms. You need to use a ratio of 1 part baking soda to 1 part cornstarch. The cornstarch also absorbs wetness and odor.

My recipe, which my son and I have used for days and are in total astonishment, no odor whatsoever.

Basic Deodorant Powder

1/2 cup baking soda (arm and hammer or generic are USP and great)
1/2 cup cornstarch
few drops tea tree oil (use this!)
a couple whole bay leaves

Combine in airtight shaker. I have seen some recommend applying to wet washcloth and then to underarm, which would only clump and makes no sense. Instead, I apply to a cream base (below) or you may apply to clean, moist underarms with a simple cotton ball or makeup kabuki brush. Press, don't brush on, so underarms look powdery.

That's it. You shouldn't have to reapply.

I use a cream base with the above for best results. My husband does not.


Cream Base

3 T coconut oil (I use Spectrum organic)
2 drops tea tree oil
2 T rosewater (optional)
1 Vit E capsule (broken before use, don't use capsule itself!)

Microwave the above to melt. Stir to combine. Will harden upon use. Store in jar. Body heat melts this. Smooth some on wet or dry underarms. It should feel nice. Then apply above powder by pressing on with dry kabuki or dry cotton ball.

We are astonished by results. For the first time , ever, we have no breakthrough odor 24 hours after application. Why did we not discover this deodorant that our ancestors probably used earlier?

It costs pennies to make. No odor whatsoever. May reapply if necessary (going out?) but 24 hours after applying, next morning, we can detect a whiff of any odor whatsoever--just fresh clean underarms. Try it!

I've been using baking soda as an underarm and foot deodorant for 2 years now. I do get darkening and dry skin under one armpit (weird, I know), but that's only occasionally. I can actually go for 3 days between re-using, but I usually shower every other day.


I keep an old spice container filled with baking soda, sprinkle a little on my hands, add a couple drops of water, mix the paste with both hands and apply under arms. For feet I just add a dusting of baking soda to my shoes.

The reason the baking soda feels and looks like it's burning, is because it is. It has a PH of around 8.3, our skin is much lower, around 7. It is literally causing alkaline burns. You could try using a buffer and a lot less baking soda, but some people are just really sensitive. It's worth knowing sensitive deodorants tend to be a PH 5 to 6.

Here's my recipe:

3 Tbsp. coconut oil/vegetable fat
3 Tbsp. arrowroot (or cornstarch if your not allergic)


1 tsp. of bicarbonate of soda (baking soda)
essential oils and/or aloe vera gel

You basically need a lot of buffering so your skin doesn't get wrecked!

My favorite way to use baking soda for reasons both healthy and frugal is as an underarm deodorant. I have tried various natural deodorants and all have fallen short in controlling odor. Because baking soda balances ph levels and neutralizes acid, it works and I find the effects of it work all day long.

To make your own inexpensive and natural deodorant, combine equal amounts of baking soda and cornstarch. I add a few drops of pure lavender essential oil for fragrance (plus this works as a bacteria inhibitor) and place in a tightly sealed bowl, add a powder puff and voila!, you'll have the most effective, simple and money saving natural deodorant one might find.

Natural Baking Soda As Underarm Deodorant

Another deodorant can be rubbing alcohol. Just put it in a spray bottle and spritz underarms. It is a disinfectant as well as deodorant. You can also use it as a hand sanitizer. (01/23/2008)

Natural Baking Soda As Underarm Deodorant

This is EXACTLY what I have been using as deodorant for almost 20 years now. I like to spray alcohol under my
arms (a squirt bottle works too) and when it's almost
dry I dust on some of my deodorant with the powder puff. In summer, or when I'm working outside in the heat,
I prefer to use white vinegar first. Make sure it is completely dry and then dust with the powder. It works better than anything else I've ever tried. Just be sure
the vinegar is dry or you will get that famous "volcano"
reaction as the dry baking soda comes into contact with the vinegar. Don't want a volcano under your arms! (01/23/2008)

I have a friend (an RN) whose husband (auto mechanic) has used this for decades, not because of health or environmental reasons, but because it works. (01/24/2008)
