Simple 3 Ingredient Deodorant

Deodorant is one of those necessary things. No one wants to be the “stinky friend”! The problem is that most store-bought deodorants contain lots of yucky ingredients, the worst offender in my opinion, being aluminum.

Aluminum is in Antiperspirants

Most deodorants are also antiperspirants. This is especially true for women’s deodorants. The ingredient that stops you from sweating is aluminum. Aluminum is a natural mineral (just because something is natural doesn’t make it safe!). In fact, it is the most prevalent metal in the earth’s crust.

Aluminum Causes Diseases

In the 1960’s doctors found elevated amounts of aluminum in the brains of recently-deceased people who had Alzheimer’s Disease. The research continues and today there is mounting evidence that aluminum is linked to neurodegerative diseases like Alzheimer’s Disease. Here is one study on Alzheimer’s done by the University of British Columbia.  Aluminum may also be linked to breast cancer. Just one example is an Italian study on breast cancer and aluminum study of 17 women who had undergone mastectomies found that the women who used antiperspirants had elevated amounts of aluminum in their breast tissues. Concentrations were higher in their underarm area. Although the link to breast cancer is less clear than Alzheimer’s, it is still a concern!

Everyone Agrees Aluminum Exposure is a Problem

Our bodies are able to excrete small amounts of aluminum very easily. The World Health Organization aluminum guidelines say that the daily limit of aluminum should be 40mg per kilogram of body weight.

The problem is that aluminum is in a shocking number of things: foods like corn, yellow cheese, baking soda, self-rising flour, salt, baby formula, and other processed foods. It is also in aluminum cooking pans, utensils, and aluminum foil (duh). Personal products like lotions, sunscreens and shampoos can also contain aluminum. Aluminum is in antacids and may also be in drinking water!

Even the CDC has issued a public health statement about the dangers of aluminum to our health.

Why Expose Yourself Unnecessarily?

When you use an antiperspirant, no very much aluminum makes it into your body. Only about .012% according to one study on aluminum by the University of Kentucky. However, when you multiply that by daily use over many years, the amount is significant! Since I know I will be exposed to aluminum other places, antiperspirants are one easy place for me to limit my exposure.

Deodorant Recipe

I’ve tried store-bought deodorants which do not have antiperspirants and had limited success, so I decided to make my own.


2 Tablespoons Baking Soda (I buy this in bulk since I use it for cleaning)

2 Tablespoons Cornstarch

2.5 Tablespoons Coconut Oil


In a small bowl, mash all ingredients together with a fork. Transfer it to an empty deodorant container for easy application. If you don’t have one, you can also buy an empty deodorant holder. You can also just put it in a small jar and use your fingers for application.

Baking soda can cause irritation, so if you find that your skin breaks out in a rash, try decreasing the baking soda and increasing the corn starch.
