Deodorant rash is a reaction to antiperspirant or deodorant that can create an itchy rash and may be caused by deodorant ingredients. Some of the ingredients that can cause negative reactions include preservatives, fragrances, and aluminum. Other ingredients that can cause an underarm rash and irritation include alpha hydroxy acids (AHAs), talc, and propylene glycol. To avoid irritation and reactions, it is recommended to test the product on a small, visible area of your skin before using it on a larger area of skin. Here are some ingredients that are commonly found in deodorants or antiperspirants that can have negative side effects on your body and may contribute to underarm skin irritation:
- Triclosan: This preservative ingredient is usually added as an antibacterial agent in personal care products. It can disrupt and harm your endocrine system, causing improper hormone functions.
- Baking Soda: Often found in “natural” deodorants, baking soda has a high pH level which can cause skin irritation.
- Aluminum compounds and salt: These are commonly used in antiperspirants to stop sweating, but they can cause skin irritation and have been linked to developmental or reproductive issues, as well as cancer.
- Talc: This is a common ingredient in deodorants that can cause skin irritation.
- Parabens: These are preservatives that were once included in many personal care products. They can trigger an allergic rash or irritation.
- Propylene Glycol: This is a very common chemical compound that is found almost everywhere. It is used to give deodorants a nice cylindrical shape that does not crumble, as well as used to prevent the formation of ice on airplane wings. It can cause skin irritation.
It is important to note that every persons skin tolerates specific ingredients differently, so you may experience a rash from an ingredient that doesnt fit neatly into the categories above. If you have symptoms of a deodorant allergy, it is recommended to see a doctor or allergy specialist to confirm your diagnosis.
