Aluminum zirconium trichlorohydrex gly

Aluminum zirconium trichlorohydrex gly (CAS 134375-99-8), also marketed as aluminum zirconium octachlorohydrex gly, is an aluminum-zirconium complex used as the active antiperspirant ingredient in personal care formulations.

Where is Aluminum zirconium trichlorohydrex gly used?

• Antiperspirant deodorant sticks, roll-ons, aerosols and creams
• Clinical-strength or sport-positioned products needing enhanced efficacy and longer-duration protection
• Prescription-adjacent antiperspirant formulations where regulatory frameworks permit higher active concentrations
• Sensitive-skin lines, where glycine complexation improves skin compatibility
• It temporarily blocks eccrine sweat glands, reducing perspiration output at the skin surface.

Good to know: Buyers should confirm the buffered or unbuffered designation, which affects pH behavior in finished formulations. Standard grades conform to USP monograph specifications, with active aluminum content and zirconium-to-aluminum ratios defined as key quality parameters.
