polymerization and Al2O3 concentration. As the acid is neutralized in the manufacturing process, the aluminum portion of the product becomes more polymerized, resulting in higher cationic charge and increased performance capabilities. The degree of acid neutralization is measured by basicity. Basicity can range from 0% (aluminum chloride solution) to 83% (aluminum chlorohydrate solution). Typically available Polyaluminum Chloride solution products have basicities ranging from 10-70%.
