Chemical Properties
ZIRKONAL® powders are stable under anhydrous conditions. Aqueous / alcoholic solutions of ZIRKONAL® are slightly acidic. At pH values > 5, insoluble Al/Zr Hydroxides precipitate out. On drying, the residue decomposes to HCl and Hydroxides. On further heating, to temperatures >100°C, the Hydroxides release water.
Physiological Properties
According to the application area and concentration applied, ZIRKONAL® exhibits sweat reducing, deodorant, astringent, antibacterial and antiphlogistic properties.
Applications & Uses
- Recommended Uses & Known Applications
ZIRKONAL® L435G is primarily used in aqueous, aqueous/alcoholic or emulsion formulations, e.g. roll-ons and creams, where maximum antiperspirant efficacy is required. According to the FDA guidelines, only non-aerosol dosage forms are allowed. The maximum permitted concentration of ZIRKONAL® L435G is 20 %, calculated on an anhydrous basis, omitting from the calculation any buffer component present in the compound.
