Abstract:
A deodorizing composition useable as an additive in one or more steps of a carpet cleaning method, said composition comprising:(A) an effective amount of odor control agent to provide a significant reduction in malodor that exists in carpet, wherein said odor control agent is selected from the group consisting of: (i) from about 0.1% to about 50%, by weight of said deodorizing composition, of solubilized, uncomplexed cyclodextrin; (ii) from about 0.0005% to about 1% by weight of said deodorizing composition, of odor blocker; (iii) from about 0.01% to about 1%, by weight of said deodorizing composition, of aldehydes selected from the group consisting of class I aldehydes, class II aldehydes, and mixtures thereof; (iv) from about 0.01% to about 5%, by weight of said deodorizing composition, of flavanoid; (v) from about 0.1% to about 10%, by weight of said deodorizing composition, of metallic salts; and (vi) mixtures thereof; (B) optionally, an effective amount of water soluble polymer for improved odor control benefit; (C) optionally, an effective amount to improve acceptance of the composition, of an emulsion comprising perfume in addition to said odor blocker, class I aldehydes, class II aldehydes, and/or flavanoids, wherein said perfume, when present, being in addition to said odor blocker, class I aldehydes, class II aldehydes, flavanoids, and/or metallic salts; (D) a cyclodextrin compatible surfactant selected from the group consisting of: (i) siloxane surfactants, (ii) castor oil surfactants, (iii) glycerol mono-fatty acid ester surfactants, (iv) fluorocarbon surfactants, and (v) mixtures thereof, (E) optionally, at least about 0.1%, by weight, of a soil suspending agent selected from the group consisting of a water-soluble substituted or unsubstituted, modified or unmodified polyalkyleneimine soil suspending agent, said soil suspending agent comprising a polyamine backbone; (F) optionally, an effective amount, to kill, or reduce the growth of microbes, of water soluble antimicrobial active; (G) optionally, from about 0.01% to about 5%, by weight of said deodorizing composition, of low molecular weight polyol; (H) optionally, from about 0.001% to about 1%, by weight of said deodorizing composition, of chelating agent; (I) optionally, at least about 0.001%, by weight of said deodorizing composition, of brightener; (l) optionally, from about 0.0001% to about 0.5%, by weight of said deodorizing composition, of solubilized, water-soluble, antimicrobial preservative; and (J) aqueous carrier that optionally comprises up to 20% of a lower molecular weight, water soluble alcohol; said composition being essentially free of any material that would soil or stain carpet under usage conditions and having a pH of more than about 3.
