  • Applications

    Octaaluminium zirconium pentachloride tricosahydroxide (CAS 98106-54-8) is primarily used as an antiperspirant active in cosmetics and personal care formulations, where its aluminum–zirconium hydroxychloride complex helps temporarily block sweat ducts and reduce perspiration. In industrial manufacturing, the compound may serve as a Lewis acid catalyst or processing aid in selected organic syntheses and specialty coatings formulations, under appropriate formulation constraints. It is also considered as a chemical precursor or additive in materials science applications, including the preparation of aluminum zirconate-based ceramics and ceramic coatings. Additionally, it may be explored as a crosslinking or rheology-modifying additive in certain specialty coatings or inks, subject to local regulations and formulation limits.
