In September I posted some thoughts on chemical-free and package-free personal hygiene options, including baking soda and cornstarch deodorant. I’ve been using the powdered blend for nearly two months and it works really well. The active ingredient is the baking soda (sodium bicarbonate), which works as a deodorant, not an antiperspirant. Antiperspirants inhibit the body’s physiology by clogging pores, blocking the natural release of sweat. Baking soda neutralizes odor-causing bacteria that live on the surface of the skin and hair. Some information on the controversial health effects of antiperspirants and deodorants can be found here.
As I mentioned before, I’ve never been someone who perspires heavily, but I appreciate some odor control, especially in the dog days of summer and on days when I’m particularly active throughout the rest of the year. Now that we’re into the heating season in Northeast, I’m readjusting to familiar challenges in temperature control as I move between the crisp outdoors and overly heated University buildings at work. Applying and shedding several layers of clothing throughout the day is a dance New Englanders are adept at. But there are many occasions when I enter a building and start to sweat before I can remove my mittens, scarf, coat, and sweater (usually in that order).
While the powder has indeed been very effective, I find it’s a little messy transferring it from the salt shaker to my hand to my underarms—especially when I’m in a rush (most days). Also, cornstarch is more difficult to find in bulk than baking soda and I’m always interested in using the least amount of ingredients necessary for any job. So I’ve decided to give a baking soda and water solution a whirl, which I’ve read works well for many people looking for a safe alternatives to aluminum and parabens. To start, I dropped a quarter teaspoon of baking soda into a 4 oz glass spray bottle (I could only find one with a plastic spray nozzle), filled it with water and shook it well until the baking soda disolved. Finding the right ratio might take some experimenting—too much baking soda will likely cause skin irritation and too little will be ineffective. I used it today and so far it seems to be working well! I will be sure to post updates.
