Abstract
Abstract A method and composition for deodorizing rugs is provided herein by applying a non-free flowing powder-fragrance composition onto a carpet and subsequently removing the composition, preferably by vacuuming. The invention also includes a package in the form of a shakeable canister for applying to rugs the aforementioned non-free flowing powder-fragrance composition. The non-free flowing powdered composition is made up of essentially an inorganic salt, such as sulfate, a chloride or bicarbonate or mixtures thereof, a fragrance, an antistatic and rheological control agent selected from natural and synthetic zeolites, and a liquid agglomerating agent. The composition exhibits stable non-free flowing properties, even at elevated temperatures, over a long period of time.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
192 words
A powdered carpet treating composition having stable rheological properties consisting essentially of a blend of: (a) a major amount in respect to each of the individual components in the composition of an inorganic salt selected from the group consisting of sulfates, bicarbonates, chlorides and mixtures thereof; (b) an effective deodorizing amount of a fragrance; (c) an antistatic and rheological control agent selected from the group consisting of natural and synthetic zeolites, said material being used in an effective amount sufficient to impart antistatic properties to the composition and control the rheological properties of the composition; and (d) an effective agglomerating amount of a substantially non-fragrant liquid agglomerating agent; wherein (1) a weight ratio of component (c) to component (d) is from between about 30.0:1.0 and about 0.5:1.0; (2) the critical flow value of the blend is from between about 5.0 and about 30.0 g when stored in a closed container at temperatures up to about 120° F. for at least 30 days; and (3) the effective fragrance imparting properties of the composition is maintained for at least 30 days when stored in a closed container at temperatures up to about 120° F.
