It belongs to a group of soluble aluminum salts that form a temporary barrier in the superficial portion of the sweat ducts.
Part of a system, not a label in isolation
It appears in roll-ons and cream formulas, including extra-protection ranges. The word Clinical does not disclose the concentration by itself.
The FDA lists Aluminum Sesquichlorohydrate as a permitted active ingredient at concentrations up to 25%. An assessment of a specific product must still consider its format and directions for use.
An individual reaction is possible. It should be applied only to intact skin and in the amount specified in the directions.
Do not confuse it with Aluminum Zirconium Sesquichlorohydrex Gly, which is a different compound containing zirconium.
