A combination of sweat and bacteria can cause armpit odor. Deodorant stops you from smelling by blocking moisture or masking the odor with a stronger, more pleasant scent. Commercial deodorants can cause irritation, but you can make deodorant from baking soda and other ingredients that are healthier and less irritating to the skin.
Take a quarter cup of baking soda, a quarter cup coconut oil and a quarter cup of cornstarch and combine in a saucepan.
Place the saucepan on the stove over low heat for about five minutes, until the coconut oil liquefies. Stir the mixture frequently.
Remove the saucepan from the stove and stir the mixture for one to two minutes more until it is completely smooth.
Pour the mixture into an old deodorant tube or a small jar with a lid.
Leave the mixture in the refrigerator for 12 hours. Apply solidified deodorant to armpits daily.
