More specifically, the invention relates to automatic dishwashing detergents which provide enhanced cleaning/bleaching benefits (especially tea stain removal) through the selection of cobalt bleach catalyst having the formula:?Co(NH.sub.3).sub.n (M).sub.m (B).sub.b !T.sub.ywherein cobalt is in the +3 oxidation state; n is 4 or 5 (preferably 5); M is one or more ligands coordinated to the cobalt by one site; m is 0, 1 or 2 (preferably 1); B is a ligand coordinated to the cobalt by two sites; b is 0 or 1 (preferably 0), and when b=0, then m+n=6, and when b=l, then m=0 and n=4; and T is one or more appropriately selected counteranions present in a number y, where y is an integer to obtain a charge-balanced salt (preferably y is 1 to 3; most preferably 2 when T is a -1 charged anion); and wherein further said catalyst has a base hydrolysis rate constant of less than 0.23 M.sup.-1 s.sup.-1 (25.degree. C.).Type: GrantFiled: February 6, 1997Date of Patent: January 6, 1998Assignee: The Procter & Gamble CompanyInventors: William Michael Scheper, Christopher Mark Perkins
