Nonaqueous liquid automatic dishwasher detergent composition containing a dual bleach
system |
(57) The application is directed to a nonaqueous liquid automatic dishwasher detergent
composition containing a dual bleach system. The composition contains a nonaqueous
organic carrier liquid, a chlorine bleach source and a bromide compound. In the wash
bath the chlorine source reacts with water to form hypochlorite and the bromide compound
reacts with a portion of the hypochlorite to form hypobromite. The active ingredients
of the dual bleach system are the hypochlorite and hypobromite which provide improved
cleaning performance against both proteinaceous and starchy carbohydrate soils. The
dish washing compositions comprise a nonaqueous organic carrier liquid, a surfactant,
a chlorine bleach source and a bromide compound, are stable in storage and are readily
dispersible in water.
