Claims11
A cleaning composition comprising approximately by weight:
- (a) 5% to 20% of an ethoxylated nonionic surfactant;
- (b) 2.5% to 30% of a MAP zeolite having a silicone to aluminum weight ratio of less than 1.33 and having a particle size of 2.0 to 4.2 microns which is an agglomeration of crystallites having a pore diameter of 300 to 4000 nanometers and a porosity of at least 1.1 cc/gram,
- (c) 20% to 40% of a supplemental detergent builder salt;
- (d) 0.5% to 5% of a polyacrylate polymer, wherein said polyacrylate polymer is a terpolymer of polyacrylamide, polyacrylic acid and maleic anhydride;
- (e) 0.5% to 35% of a sodium sulfate;
- and
- (f) 0.5% to 7% of an alkali metal silicate, wherein said composition does not contain a percarbonate bleach compound.

A composition comprising approximately by weight:
- (a) 5% to 60% of a MAP zeolite wherein said zeolite has a silicone to aluminum weight ratio of less than 1.33 and having a particle size of 2.0 to 4.2 microns as measured on a sedigraph, which is an agglomeration of crystallites having a pore diameter of 300-4000 nanometers and a porosity of at least 1.1 cc/gram;
- (b) 0 to 55% of an alkali metal carbonate;
- and
- (c) 10% to 40% of an ethoxylated nonionic surfactant, wherein said ethoxylated nonionic surfactant has 6 to 11 ethylene oxide groups.
