Aluminum zirconium tetrachlorohydrex gly
Aluminum zirconium tetrachlorohydrex gly is a complex of aluminum zirconium tetrachlorohydrate with glycine, which buffers and stabilizes the zirconium species. It is made by combining aluminum chlorohydrate with a zirconium hydroxychloride solution in the presence of glycine, then spray-drying. Brands buy it mainly as fine powders, standard or activated, for anhydrous sticks and soft solids, and sometimes as solutions.
Suppliers sell different products under the same name. Specify the one you need.
Spray-dried powder with a defined Al:Zr ratio and particle size for sticks and soft solids.
Grades with a modified polymer size distribution for higher activity; sold with a recommended use-by window.
Aqueous or glycol solutions for clear gels and roll-ons.
Very fine powders for clear or low-residue sticks.
Compare each result with your own specification when the lot arrives.
Store powders sealed in their original lined containers in a cool, dry place; they are hygroscopic and corrosive to metals. Activated grades lose activity over time, especially in water, so use within the supplier's stated period. Shelf life and retest dates come from the supplier's specification.
Record Al:Zr ratio, glycine, anhydrous active and particle size for each lot. Note the manufacture date of activated grades and rotate strictly first in, first out.

Suppliers are in alphabetical order and none pays to appear. Each claim is checked against the supplier’s own website on the date shown. Ask for the specification sheet and a recent COA before you order, and confirm details with the supplier.
Common forms include standard powder, activated powder, solutions and micronized grades. Ask each supplier for the specification sheet of the exact grade they quote.
