摘要:
A process for making detergent granules having a bulk density of 300 to 700 g/l. A solid carrier containing neutralizing agent is mixed in a rotating mixer with a liquid binding agent containing surfactant acid to forma partially granulated premixture. The premixture is fluidized, sprayed with additional binder, and granulated in a fluidized bed reactor to form the detergent granules.
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:
Methods for manufacturing surfactant granules, which methods comprise: (a) neutralizing an anionic surfactant acid with a solid neutralization agent, wherein the anionic surfactant acid has a water content of 5 to 24 wt %, and wherein the anionic surfactant acid and the solid neutralization agent are agglomerated in a free-fall mixer, to form surfactant granules having a bulk density of 300 to 800 g/l, are described.
摘要:
A process for making a detergent tablet by forming a disintegrating agent by compacting cellulose or a cellulose derivative, forming disintegrating agent particles comprising the disintegrating agent, dry mixing a washing- or cleaning-active substance and an amount of the disintegrating agent particles effective to rapidly dissolve or disperse the composition in water, and shaping the resulting mixture into a tablet. The disintegrating agent particles have a particle size distribution of less than 10% by weight smaller than about 0.2 mm particle size and no more than 1% by weight of dust-fine particles.

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.

A particulate washing or cleaning composition containing (A) a phosphate-free water-soluble builder component and (B) alkali metal percarbonate particles having a coating containing alkali metal silicate.
摘要:
A process for the production of solid or paste-form products by fast reactions is carried out stoichiometrically wherein a gaseous medium is introduced into each of the reactants to be reacted with one another, the reactant streams formed are combined and are subsequently forced through a spray unit in a weight ratio of gaseous medium to product stream of from 0.04 to 0.3 (kg/kg) and at a rate of 0.1 to 15 m/second, as calculated from the gas-free reactant streams and based on the free cross-section of the spray unit. The products obtained are free from readily volatile constituents.
