There are tons of recipes for natural deodorants on the internet. Unfortunately, most of them need to be kept in the refrigerator or somewhere else cool or they may melt and separate. If you’re looking for something travel friendly to make at home, this natural deodorant by Chocolate and Zucchini is a great solution. Because it has beeswax, it will remain stable all the way up to temperatures over 120 degrees Fahrenheit. Of course, if you’re taking it on a plane, remember to pack it in a small container because it is essentially a liquid, meaning you cannot take more than a 3.4 ounce container of the stuff past the TSA checkpoint.
Note that this a natural deodorant and not an antiperspirant and will not prevent sweating. So far as I know, there is no such thing as a natural antiperspirant, but this will make it so your sweat will not stink, which is the biggest sweat-concern for most people.
