Abstract
Abstract Stable, aqueous cleaning agents containing (a) anionic and/or nonionic surfactants, optionally chlorine-stable, (b) an abrasive component and/or (c) an active-chlorine-releasing compound and, optionally, (d) dyes and (e) fragrances, characterized in (f) a further content of amorphous calcium aluminum silicates precipitated in situ; and the process of their preparation wherein the various ingredients are mixed and the amorphous calcium aluminum silicates are formed by precipitation therein.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
190 words
A process for the production of a stable, aqueous cleaning agent composition comprising (a) a surfactant-effective amount of a surfactant selected from the group consisting of non-chlorine stable anionic surfaceants, non-chlorine stable nonionic surfactants, chlorine-stable anionic surfactants, chlorine-stable nonionic surfactants and mixture thereof, (b) from 0 to an abrasively-effective amount of at least one abrasive component, (c) from 0 to a bleaching-effective amount of an active-chlorine-releasing compound and (d) from 0 to an effective amount of dyes and (e) from 0 to an effective amount of fragrances, with (f) a further suspending-effective amount of an amorphous calcium aluminum silicate precipitated in situ, where an effective amount of at least one of component (b) and component (c) is present, comprising the steps of mixing component (b), if present, with an aqueous solution of component (a) and component (d) if present, at room temperature, then successively adding under continuous mixing a calcium chloride solution, an aluminum hydroxide solution and a waterglass solution in amounts sufficient to form said component (f) in situ, followed by adding component (c), if present, and component (e) if present, and recovering said stable, aqueous cleaning agent composition.
Claim 2
Dependent Claim
190 words
A process for the production of a stable, aqueous cleaning agent composition comprising (a) a surfactant-effective amount of a surfactant selected from the group consisting of non-chlorine stable anionic surfaceants, non-chlorine stable nonionic surfactants, chlorine-stable anionic surfactants, chlorine-stable nonionic surfactants and mixture thereof, (b) from 0 to an abrasively-effective amount of at least one abrasive component, (c) from 0 to a bleaching-effective amount of an active-chlorine-releasing compound and (d) from 0 to an effective amount of dyes and (e) from 0 to an effective amount of fragrances, with (f) a further suspending-effective amount of an amorphous calcium aluminum silicate precipitated in situ, where an effective amount of at least one of component (b) and component (c) is present, comprising the steps of mixing component (b), if present, with an aqueous solution of component (a) and component (d) if present, at room temperature, then successively adding under continuous mixing a calcium chloride solution, an aluminum hydroxide solution and a waterglass solution in amounts sufficient to form said component (f) in situ, followed by adding component (c), if present, and component (e) if present, and recovering said stable, aqueous cleaning agent composition.
