ALUMINUM DICHLOROHYDREX PEG.

Valuable CAS 242812-79-9 / ANTIPERSPIRANT, ASTRINGENT, DEODORANT

Aluminum Dichlorohydrex PEG is a clinically effective antiperspirant active that significantly reduces sweat production. This ingredient's polyethylene glycol (PEG) component also enhances its solubility and improves formulation aesthetics.

Summary

antiperspirant astringent

Science

Mechanism of Action

This ingredient functions by diffusing into sweat ducts, where it hydrolyzes upon contact with sweat. This process creates a temporary, insoluble aluminum hydroxide gel plug, physically blocking eccrine sweat release to the skin surface.
