ZIRCONYL CHLORIDE.

Avoid CAS 7699-43-6 / NOT REPORTED

Zirconyl chloride serves primarily as a component within aluminum zirconium complexes used in antiperspirants. It is not generally recommended for direct cosmetic application due to significant safety concerns.

Summary

Antiperspirant agent (as complex component)

Science

Mechanism of Action

This compound undergoes hydrolysis to form zirconium hydroxide, which then precipitates within sweat ducts. This action creates a physical plug, effectively reducing sweat production.
