Aluminum Zirconium Tetrachlorohydrex Gly is a composite salt containing aluminum and zirconium, with the chemical formula C₂H₈AlClNO₄Z. Its molecular structure incorporates glycine ligands and hydroxy chloride groups, classifying it as a metal coordination compound. With a high molecular weight (>1800 Da) and low transdermal absorption rate (only 0.005%), it effectively inhibits sweat secretion while minimizing skin irritation. Its unique gelation mechanism and low irritancy make it a preferred ingredient in modern antiperspirant formulations.
| Item | Specification |
| Appearance | White powder |
| Aluminum/Zirconium atomic ratio | 3.6:1 |
| Cl/Al+Zr | ≈ 0.7 |
| Density | 1.5–2.0 g/cm³ |
| Transdermal absorption rate | 0.005% |
| Hygroscopicity | Strongly hygroscopic; readily absorbs moisture to form hydrates when exposed to air. |
| Solubility | Soluble in polar solvents such as glycerin and propylene glycol; insoluble in non-polar solvents like diethyl ether and benzene. |
| Stability | Stable at room temperature, but may decompose and release hydrogen chloride gas at high temperatures (>200°C). Exhibits slow corrosion on metals (e.g., copper, iron). |
Serves as a core ingredient in personal care products like antiperspirants and deodorants.
Functions as a pharmaceutical intermediate for synthesizing aluminum- and zirconium-containing drugs, such as certain antacids or topical astringents.
Its chloride forms (e.g., tetrachlorohydroxyaluminum zirconium) serve as highly effective flocculants for purifying industrial circulating water, oilfield reinjection water, etc., removing suspended solids and impurities through adsorption and coagulation.
Used as crosslinking agents or mordants in leather tanning, textile printing, and dyeing, leveraging its metal ion coordination ability to enhance material properties.
