Aluminum
Aluminum, often found in the form of aluminum salts like aluminum chlorohydrate, is primarily used in cosmetics as an antiperspirant agent. It works by temporarily blocking sweat ducts, reducing the amount of sweat released to the skin surface. In other applications, it can function as an astringent or pigment.

Frequently asked questions
- Is aluminum safe in antiperspirants?
- Regulatory bodies generally consider aluminum compounds safe for use in antiperspirants at approved concentrations, as there is no conclusive scientific evidence linking them to serious health issues in humans.
- How does aluminum work in antiperspirants?
- Aluminum salts dissolve in sweat and form a temporary plug in the sweat ducts, which reduces the amount of sweat that reaches the skin's surface.
