Patent ID: 7229954

Claim:
An aqueous carpet cleaning composition comprising: a terpene hydrocarbon solvent that also functions as a fragrance; one or more surfactants; a soil resist component; a stain resist component that includes at least one compound selected from the group consisting of polymers containing phenol-formaldehyde, methacrylic acid, maleic acid, sulfonated fatty acids, and blends thereof; and acrylate resins; water in an amount sufficient to form an aqueous solution with the terpene hydrocarbon solvent, the one or more surfactants, the soil resist component, and the stain resist component; wherein the one or more surfactants includes at least one nonionic surfactant in an amount sufficient to stabilize the terpene hydrocarbon solvent in the aqueous solution; and a pH adjusting agent in an amount sufficient to maintain a pH of the aqueous carpet cleaning composition between about 8.5 and 9.5 to stabilize the carpet cleaning composition so that the terpene hydrocarbon solvent, the one or more surfactants, the soil resist component, and the stain resist component remain in solution.
