Patent ID: 8354366

Claim:
A water soluble pack comprising a total composition contained by a water-soluble enveloping material, wherein the total composition comprises an aqueous composition and a solid composition, and wherein the total composition is free of phosphate, wherein the aqueous composition is contained in a first compartment of the pack and the solid composition is contained in a second compartment of the pack; wherein the aqueous composition comprises water and a nonionic surfactant; wherein the nonionic surfactant comprises from about 0.1% to about 10% by weight of the total composition, wherein the solid composition comprises: an amino acid based builder; a polymer; and zinc sulfate; wherein the amino acid based builder is selected from the group consisting of a methyl-glycine diacetic acid, glutamic-N, N-diacetic, and mixture thereof, and wherein the amino acid based builder comprises from about 5% to about 60% by weight of the total composition; wherein the polymer is selected from the group consisting of a sulfonated polymer, carboxylated polymer, and a mixture thereof, and wherein the polymer comprises from about 0.5% to about 20% by weight of the total composition; wherein the zinc sulfate comprises from about 0.1% to about 5% by weight of the total composition.
