摘要:
A washing and cleaning agent shaped body in the form of a granulate, extrudate, agglomerate, or tablet, containing fine microparticles that contain one or more washing or cleaning agent components, wherein the fine microparticles form the shaped body as such or are present within it. The washing or cleaning agent component is selected from surfactants, fragrances, dyes, enzymes, enzyme stabilizers, builders, substances to adjust the pH, bleaches, bleach activators, silver protectants, soil-repelling substances, optical brighteners, antiredeposition agents, disintegration auxiliaries, and mixtures thereof. At least 10% of the fine microparticles, based on the total number of microparticles, have a particle size distribution of ≦20 μm.
摘要:
A process for producing a detergent portion, comprising the steps of forming one or more dimensionally stable hollow bodies comprising at least one compartment by injection moulding, providing one or more means for compartmentalizing the dimensionally stable hollow bodies, filling the compartment with at least one detersive formulation, and closing the compartment to form a partial or whole enclosure around the detersive formulation.
摘要:
A fluidized bed apparatus for the production and treatment of granules and a method for its operation is provided. The fluidized bed apparatus includes an entry chamber through which a gas is designed to flow upwards; a fluidization chamber for fluidizing the material located above the entry chamber; pivotal slats located between the entry chamber and the fluidization chamber; and a nozzle arm located in the chamber below the slats with a nozzle line ending in a nozzle which is directed into the fluidization chamber through cutouts in the slats and extends partly into the fluidization chamber. The fluidized bed apparatus has rigid nozzle arms and lines which are easily jacketed for heating and cooling applications.
摘要:
A spray-dried amorphous alkali metal silicate compound which provides multiple-cycle washing performance. The silicate compound has a molar ratio of M2O to SiO2 of 1:1.5 to 1:3.3 wherein M represents an alkali metal. The compound contains 0.5 to less than 30% by weight of anionic surfactant and has an absorption capacity for liquid components which is at least 20% higher than that of the same quantity of the alkali metal silicate compound which is free from anionic surfactant.
摘要:
The invention is a process for producing surfactant granules by mixing a water-containing surfactant with a solid to form granules, drying the granules and recycling the dried granules as a portion of the solid.
摘要:
A process for producing free-flowing granules comprising the steps of (a) drying with superheated steam an aqueous mixture containing at least one surfactant selected from the group consisting of anionic surfactants and nonionic surfactants to form carrier granules having a porous inner structure, and (b) impregnating the porous inner structure of the carrier granules with an aqueous coating composition selected from the group consisting of wetting agents, detergents, cleaning agents, and mixtures thereof, to form an impregnated carrier granule.
摘要:
A process for preparing free-flowing granules containing a bleach activator and a substantially water-free binder for the bleach activator. The process consists essentially of premixing a mixture of anionic and nonionic surfactants and the bleach activator, homogenizing the resulting mixture to form a paste which is extrudable in strand form, extruding the paste under elevated pressure, and cutting the extrudate into granules.
摘要:
The invention is a process for manufacturing granules of a washing or cleaning agent from an at least partly solid mixture of granules by admixing plasticizers or lubricants with the granules and passing the mixture through a mixing zone at an elevated temperature and pressure to form a plastic flowable material and passing the plastic flowable material through a plurality of orifices of small diameter and cutting the extruded material at predetermined lengths to form a particulate washing or cleaning agent.
摘要:
A detergent tablet having at least one phase in the form of a solid foam having gas-filled cells delimited by solid partitions, and the tablet or the at least one phase comprises 40% to 90% by weight of one or more water-soluble polymers. A process for the production of detergent tablets by foaming a solution, melt, emulsion, or suspension comprising at least one active ingredient with a gaseous medium, and solidifying the resulting foam.
摘要:
A textile aftertreatment composition comprising (a) a skin-protecting oil and (b) urea and/or urea derivative; lactic acid and/or a lactic salt; citric acid and/or a citric acid salt wherein the composition is in the form of an emulsion. The composition is conducive directly or indirectly to the health of the skin and can be used as a supplement to the classical textile treatment compositions such as laundry detergents or fabric softeners.
