For adults: this ingredient is commonly used in antiperspirants and is generally considered low risk when you use it as directed. The biggest issues are skin irritation and that some agencies place limits on its use.
Use products with this ingredient only as directed (typically small amounts to the underarm). Do a small patch test on normal skin before regular use. Do not put it on broken, chapped, or irritated skin. If you notice redness, itching, swelling, or a rash, stop using the product and see a doctor. If you are pregnant or breastfeeding and worried, talk with your healthcare provider about alternatives.
Avoid using on broken skin and watch for signs of contact allergy (redness, itching, blistering). Some regulatory bodies have usage restrictions (see Health Canada and cosmetic ingredient restriction lists). There are a few studies with limited or mixed findings related to cancer and some animal studies at high doses; these are reasons some groups restrict or limit its use.
