Abstract: An enhanced antiperspirant active having improved stability and a process for preparing the enhanced antiperspirant active solution are disclosed, the process comprises blending an enhanced basic aluminum chlorohydrate antiperspirant active having a peak 4 content of at least 20% (Component A) with a zirconium hydroxychloride neutral amino acid complex (component B) and a conventional basic aluminum chloride (Component C) , the order of addition not being critical; wherein at least 10% by weight of the total aluminum being derived from Component A and about 90% to 10% of the aluminum being derived from Component C; thereby forming a stable antiperspirant active solution of enhanced efficacy, the overall concentration of reactants in solution being about 38% to 55% by weight.

Abstract: An improved method for preparing a basic aluminum hyrdoxy-chlorosulfate is disclosed comprising reacting a basic aluminum chloride with a sulfate source, i.e. H.sub.2 SO.sub.4 or aluminum sulfate, and modifying the reaction product by the addition of minor amounts of calcium containing compound and a water soluble iron salt. The product is useful in water treatment, is effective in cold water as well as low alkalinity water. A magnesium compound can be added to the composition where the calcium source contains no magnesium.

Abstract: A residue free, antiperspirant gel stick composition is disclosed which comprises an antiperspirant compound which is soluble in a diol, a normally liquid, water soluble diol, a gelling agent and a zinc glycinate in amount sufficient to control the pH of the gel stick at about 4.1 to about 5.0, the glycine to zinc mole ratio of the zinc glycinate added being about 2.0/1 to about 3.0/1. The process for preparing a diol soluble antiperspirant active useful in preparing the residue free gel stick is also disclosed and comprises reacting an antiperspirant compound with a water soluble, normally liquid diol in a water solution by heating for about 1 to about 100 hours at a temperature of about 50.degree. C. to about 110.degree. C.; adding a zinc glycinate to the reaction mixture and removing the water to recover a powdered antiperspirant active.
