  • Patent number: 5164106
    Abstract: 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 dishwashing 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.

  • Patent number: 5160657
    Abstract: In a process for preparing a granular detergent composition or component having a bulk density of at least 650 g/l, which comprises the steps of treating a particulate starting material(i) in a first step in a high-speed mixer/densifier, the mean residence time being from about 5-30 seconds;(ii) in a second step in a moderate-speed granulator/densifier, whereby it is brought into, or maintained in, a deformable state, the mean residence time being from about 1-10 minutes and(iii) in a final step in drying and/or cooling apparatus,the amount of oversize particles can be effectively reduced by adding 0.1 to 40% by weight of a powder in the second step or between the first and the second step. Preferably, the deformable state is induced in the first step.
