摘要:
Free-flowing and storable granular compacts containing ingredients of detergent or cleaning compositions in concentrated form are prepared by(1) preparing an adhesively bound dry premix containing(a) fine-particle detergent ingredients substantially free of binding or adhesive properties, and(b) fine-particle detergent ingredients having binding or adhesive properties, and optionally, detergent ingredients which are liquid at room temperature, to form a substantially homogeneous premix, and(2) press-molding the premix at a temperature of from about 40.degree. C. to 80.degree. C. in the substantial absence of shear forces whereby air is microdispersed in the resultant compacts.
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 process of producing a detergent in the form of portioned pressings by extrusion of a homogeneous premix containing a plasticizer or lubricant into strands through a perforated die under a pressure of from about 25 to about 200 bar and forming compacted granules thereof, and then pressing the compacted granules into portioned pressings such as tablets.
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 process for the production of compacted granules for use in a detergent composition by providing a homogeneous, solid, free-flowing premix to which a plasticizer or lubricant is added, and extruding the mixture through a perforated die under a pressure of from about 25 bar to about 200 bar to form strands of the mixture. The perforated die has an opening width corresponding to a predetermined size of the granules. After emerging from the perforated die, the strands are cut to the predetermined size of the granules by means of a cutting unit. The process enables the preparation of detergent compositions containing increased contents of surfactant components.
摘要:
The process of preparing granules of sodium perborate monohydrate having an increased density by dry-compacting a mixture of sodium perborate monohydrate and from about 0.2 to about 30% by weight of a compacting aid, based on the weight of the mixture. The compacting aid is selected from the group consisting of an alkali metal salt, alkaline earth metal salt, carbohydrate, anionic surfactant, and nonionic surfactant. After forming a compactate of the mixture, the compactate is size-reduced to obtain granules having the desired particle size.
摘要:
Detergent portions containing at least one detersive formulation wholly or partly contained in a dimensionally stable hollow body having an enclosure that wholly or partly surrounds the detersive formulation, the enclosure being formed of an uncompressed material that can disintegrate under laundering, cleaning, or washing conditions and that gives the hollow body dimensional stability, and optionally, the dimensionally stable hollow body having one or more means forming one or more compartments therein.
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:
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 provides an enzyme containing granule with a coating containing a silver corrosion inhibitor. The particle is formed from a core containing a first enzyme and an organic or inorganic carrier which can be coated with a second particulate enzyme. The core is coated with a coating containing at least one salt of manganese, titanium, zirconium, hafnium, vanadium, cobalt and cerium. A method for preparing the granule is also disclosed.
