摘要:
A method for producing a liquid preparation having a solid body content and the resulting liquid preparation. According to the method, the addition of at least a portion of the solid bodies takes place only (a) in the last stage of the method preceding the pouring of the liquid preparation into a packing unit or (b) during the pouring into a packing unit.
摘要:
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.
摘要:
Capsules which comprise an immobilized active ingredient in a matrix, wherein the active ingredient is bound to a substrate, and cleaning/detergent compositions comprising such a capsule and a surfactant, methods for the preparation of such compositions and their use are described.
摘要:
The invention relates to an aqueous detergent or cleaning agent, containing one or more surfactants, a polyacrylate as a thickening agent, a solvent component comprising dipropylene glycol, in addition to other usual detergent and cleaning agent substances. The thus obtained aqueous detergent or cleaning agent is clear, transport and storage stable, has a flow limit and can disperse particles in a stable manner and over a long period of time.
摘要:
A gel capsule, loaded with at least one organic percarboxylic acid is manufactured by the process comprising the steps of: (a) providing an oil having a melting point below 35° C. at atmospheric pressure and that is inert towards the organic percarboxylic acid; (b) contacting the oil with at least one stabilizer at a temperature of from 25° C. to 50° C. to obtain a liquid matrix medium comprising the oil and the stabilizer, (c) optionally cooling the matrix medium resulting from step (b) to a temperature above the gel-formation temperature of the matrix medium; (d) incorporating at least one organic percarboxylic acid in the form of solid particles into the liquid matrix medium obtained in step (b) to form a dispersion of the solid percarboxylic acid in the liquid matrix medium; (e) contacting the matrix medium obtained in process step (d), with a dispersion agent at a temperature below the gel-formation temperature to form gel capsules, wherein the organic percarboxylic acid is incorporated in an oil/stabilizer-gel matrix.
摘要:
A multilayer capsule is comprised of a core-shell structure wherein the core portion comprises at least one organic peroxycarboxylic acid in solid particulate form and the shell portion comprises at least one coating layer comprising a material selected from the group consisting of at least one polyelectrolyte, at least one ionic surfactant or a combination thereof.

摘要:
Processes which comprise: (a) blending a solid component and a liquid component in a mixer/granulator to form an intermediate granule mix; and (b) further treating the intermediate granule mix in a fluidized bed granulator to form granules; wherein a first portion of the liquid component is introduced into the mixer/granulator and a second portion of the liquid component is introduced into the fluidized bed granulator are disclosed. The solubility of granules prepared in accordance with the disclosed processes can be manipulated. Detergent and/or cleansing agents containing such granules and tablets incorporating such agents, as well as their use, are also described.
摘要:
Particles containing imidoperoxycarboxylic acid can be produced by granulating a combination of imidoperoxycarboxylic acid and phlegmatizing agent and optionally granulation auxiliary and subsequently coating the granules with a water-soluble coating material. They can be used as bleaches or bleach component in, in particular, particle-shaped detergents and cleaners and for the production thereof.
摘要:
Provided is a method for producing surfactant granulates, comprising (a) providing a mixture of anionic surfactant acids and builder acids having a weight ratio of 1:100 to 1:20 of builder acid to surfactant acid; and (b) contacting the mixture with at least one solid neutralizing agent. The builder acid is selected from citric acid, tartaric acid, succinic acid, malonic acid, adipic acid, maleic acid, fumaric acid, oxalic acid, gluconic acid, nitrilotriacetic acid, aspartic acid, ethylenediaminetetraacetic acid, aminotrimethylenephosphonic acid, hydroxyethanediphosphonic acid, polyaspartic acids, polyacrylic acids, polymethacrylic acids, or copolymers thereof and has a particle size below 200 μm.
