Aluminum chlorohydrex

Aluminum chlorohydrex (CAS 53026-85-0) is a polymeric aluminum salt used primarily as an antiperspirant active in personal care formulations.

Where is Aluminum chlorohydrex used?

• Antiperspirant products: sweat reduction in roll-ons, sticks and aerosol sprays
• Pharmaceutical-grade preparations: active ingredient for clinical-strength antiperspirants targeting hyperhidrosis
• Water treatment: coagulant that destabilizes suspended particles and colloidal matter
• It forms a temporary plug in sweat ducts, reducing perspiration at the skin surface.

Good to know: Improved skin compatibility compared to anhydrous aluminum chloride for daily use. The propylene glycol complex form, aluminum chlorohydrex PG, is commonly specified for enhanced solubility in anhydrous stick formulations.

Commercial specifications

• Stability across pH ranges and compatibility with emollient bases are selection criteria
