Aluminum Zirconium Tetrachlorohydrex Gly

Aluminum Zirconium Tetrachlorohydrex Gly is an inorganic salt complex combining aluminium, zirconium, and chloride. It is primarily used as an antiperspirant and astringent agent in skincare and cosmetic formulations.

When applied to skin, this ingredient works by forming a protective layer that helps reduce the appearance of excess moisture and may provide a slight tightening or drying effect on the skin surface.

This ingredient functions by forming a thin, occlusive barrier on the skin's surface that temporarily reduces the visible appearance of moisture and perspiration. The astringent properties come from the salt's ability to draw water from the outer layers of skin, creating a tightening or pore-minimising effect.

The mechanism is largely physical rather than chemical, meaning the effect is temporary and depends on the ingredient remaining on the skin surface.

This ingredient is most commonly found in antiperspirant and mattifying products rather than general skincare. If using a product containing it, apply to clean, dry skin. Allow any liquid formulation to dry completely before applying other products, as layering may reduce efficacy. It is generally intended for daily use in products formulated with this ingredient as a primary active.
