Abstract
Bleach compositions comprising certain carboxylate-containing cobalt catalysts are provided. More specifically, the invention relates to automatic dishwashing detergents and laundry compositions which provide enhanced cleaning/bleaching benefits (especially tea stain removal) through the selection of cobalt catalysts having the formula: EQU Co(NH.sub.3).sub.5 M!T.sub.y wherein cobalt is in the +3 oxidation state; and M is a substituted and unsubstituted C.sub.1 -C.sub.30 carboxylate-containing ligand having the formula RC(O)O--.
