Abstract
Abstract Substantially, builder-free, liquid, suspension-stable multipurpose cleaning preparations containing abrasives, a surfactant base of mixtures of anionic surfactants or anionic surfactants and amphoteric surfactants, and water, and having a pH-value of from 5.5 to 9.5. These preparations can be used for cleaning hard surfaces of all kinds and in particular can be used as dishwashing detergents, multipurpose cleaners, scouring preparations and/or polishes.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
296 words
A builder-free aqueous, liquid, suspension-stable multipurpose cleaning composition consisting essentially of: A. from about 10 to about 35% by weight, based on the weight of the cleaning composition, of a mixture of at least two of the following: (a) at least one anionic sulfonate surfactant, (b) at least one anionic sulfate surfactant, and (c) at least one amphoteric surfactant, wherein when the mixture consists of a mixture of (a) and (b), from about 5 to about 95% by weight of (a) and correspondingly from about 95 to about 5% by weight of (b) is present, based on the weight of the mixture, and when the mixture consists of (c) and either one or both of (a) and (b), then (c) is present in from about 0.5 to about 15% by weight, based on the weight of the cleaning composition, provided that when (c) is present the ratio by weight of (a) or (b) or (a)+(b) to (c) is from about 20:1 to about 1:1; B. from about 5 to about 20% by weight, based on the weight of the cleaning composition, of at least one abrasive having a particle diameter of from about 5 to about 15 μm; C. at least one viscosity regulator in amount sufficient to regulate the viscosity of the cleaning composition to from about 4,000 to about 6,000 mPas; D. from 0.3 to about 1% by weight based on the weight of the cleaning composition, of fat solvent selected from a terpene hydrocarbon, a terpene alcohol, and a glycol ether having a molecular weight of greater than about 200,000 to about 4,000,000; E. a pH regulator in amount sufficient to provide a pH in the range of from about 5.5 to about 9.5 for the cleaning composition; and F. the remainder, water.
Claim 2
Dependent Claim
296 words
A builder-free aqueous, liquid, suspension-stable multipurpose cleaning composition consisting essentially of: A. from about 10 to about 35% by weight, based on the weight of the cleaning composition, of a mixture of at least two of the following: (a) at least one anionic sulfonate surfactant, (b) at least one anionic sulfate surfactant, and (c) at least one amphoteric surfactant, wherein when the mixture consists of a mixture of (a) and (b), from about 5 to about 95% by weight of (a) and correspondingly from about 95 to about 5% by weight of (b) is present, based on the weight of the mixture, and when the mixture consists of (c) and either one or both of (a) and (b), then (c) is present in from about 0.5 to about 15% by weight, based on the weight of the cleaning composition, provided that when (c) is present the ratio by weight of (a) or (b) or (a)+(b) to (c) is from about 20:1 to about 1:1; B. from about 5 to about 20% by weight, based on the weight of the cleaning composition, of at least one abrasive having a particle diameter of from about 5 to about 15 μm; C. at least one viscosity regulator in amount sufficient to regulate the viscosity of the cleaning composition to from about 4,000 to about 6,000 mPas; D. from 0.3 to about 1% by weight based on the weight of the cleaning composition, of fat solvent selected from a terpene hydrocarbon, a terpene alcohol, and a glycol ether having a molecular weight of greater than about 200,000 to about 4,000,000; E. a pH regulator in amount sufficient to provide a pH in the range of from about 5.5 to about 9.5 for the cleaning composition; and F. the remainder, water.
