Widely used in antiperspirant products due to its ability to temporarily block sweat glands. It reduces perspiration by forming gel-like plugs on the surface of sweat ducts, which helps control wetness and body odor. Commonly found in roll-ons, sprays, and solid sticks. Its effectiveness stems from the combined action of aluminum and zirconium, which enhance sweat reduction compared to aluminum-only compounds. Often combined with other ingredients to improve skin compatibility and product stability.
