ABSTRACT:
A method and composition for inhibiting foam formation in automatic dishwashers are described. The composition comprises an anti-foam system having 0.01 to 1% of certain hydrophobic particulate solids combined with 0.01 to 4% of high viscosity hydrocarbon polymers; 1 to 30 wt. % of a bleaching agent; 1 to 40 wt. % of a surfactant; 0.1 to 10 wt. % of an enzyme; and 1 to 75 wt. % of a builder, the composition having a pH of less than about 11.
