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.
