Aluminum Chlorohydrex PG is an aluminum salt derivative primarily utilized for its antiperspirant properties. It effectively reduces sweat production by temporarily blocking sweat ducts.

Summary

antiperspirant astringent

Science

Mechanism of Action

This acidic aluminum salt diffuses into sweat pores. Upon contact with the higher physiological pH of sweat, it forms an insoluble polymer complex, creating a temporary plug that prevents sweat release.
