Aqueous washing and cleaning agents that contain capsules in addition to other constituents, the capsules each encompassing an active ingredient in a matrix. The introduction of a combination of aluminum silicate and silicic acid into the matrix improves the solubility characteristics of the capsules in a washing operation.
Claims25
An aqueous liquid washing or cleaning agent comprising a surfactant and least one capsule, the capsule comprising, encapsulated in a matrix, an active ingredient, an aluminum silicate, and a silicic acid, the aluminum silicate and the silicic acid being present in the matrix in a ratio from 1:10 to 10:1.
A method of cleaning a textile fabric comprising the steps of contacting a textile fabric with a cleaning-effective amount of a liquid washing or cleaning agent, the agent comprising a surfactant and least one capsule, the capsule comprising, encapsulated in a matrix, an active ingredient, an aluminum silicate, and a silicic acid, the aluminum silicate and the silicic acid being present at a ratio from 1:10 to 10:1.
A method of manufacturing an aqueous liquid washing or cleaning agent, comprising combining a surfactant and at least one capsule, wherein the capsule is formed by encapsulating in a matrix an active ingredient, an aluminum silicate, and a silicic acid, wherein the aluminum silicate and the silicic acid are present in the matrix in a ratio from 1:10 to 10:1.
A capsule comprising, encapsulated in a matrix, an active ingredient, an aluminum silicate, and a silicic acid, wherein the matrix comprises the aluminum silicate and the silicic acid in a ratio from 1:10 to 10:1.
