The invention describes processes for the production of basic aluminum compounds, including aluminum chlorohydrate, basic zirconium compounds, and basic aluminum zirconium compounds. The process produces products of a wide range of basicities. The products formed by the present invention are comprised of low molecular weight species characteristic of enhanced efficacy antiperspirant salt compositions. The products of this process are suitable for use as water purification agents, as binders in catalyst applications, and in antiperspirant applications. In addition, the invention is directed to the products made by the disclosed process.

Polymetal hydroxychloride processes and compositions: enhanced efficacy antiperspirant salt compositions

The invention relates generally to processes for the production of high-basicity and ultra-high basicity polyaluminum chlorides including aluminum chlorohydrate. The processes can produce products of a wide range of basicities and are particularly useful in producing high basicity products. The process can produce a wide range of solution concentrations and are particularly useful in producing high solution concentrations. The processes described generate high purity products, which are free of by-product salt(s). The processes described herein can also be utilized to produce enhanced efficacy polyaluminum chlorides including aluminum chlorohydrate. When compared to conventional processes for manufacturing these compounds the processes disclosed herein are unique in so far as the disclosed processes do not require aluminum metal as a starting material. The products of the processes are suitable in applications including water purification, catalysts, and antiperspirants. In addition, the invention is directed to the products prepared by the processes described herein.
