    • There is provided a process for the production of a detergent granule comprising at least 40% by weight of an anionic surfactant and suitable for use as a granular detergent composition or a component thereof, which comprises the steps of (i) neutralising an anionic surfactant precursor with a source of alkali, (ii) adding Na2SO4 and Na2CO3 to form a slurry and (iii) spray-drying the obtained slurry to form a granule, whereby the molar ratio of Na2SO4 to Na2CO3 is in range of 1 : 0.9 to 1 : 1.3, and whereby the double salt Na2SO4.Na2CO3 is formed and whereby the slurry comprises a polycarboxylate polymer. There is also provided a spray-dried detergent carrier granule comprising at least 40% by weight of an anionic surfactant and suitable for use as a granular detergent composition or a component thereof, comprising (i) linear alkylbenzene sulphonate (LAS), soap and mixtures thereof, and (ii) the double salt Na2SO4.Na2CO3 obtainable by the process of the present invention. A third aspect is a detergent composition comprising such granules.

    • The invention provides a method for the cleaning of a soiled substrate, the method comprising treating the substrate with a non-polymeric solid particulate cleaning material and wash water, the treatment being carried out in an apparatus comprising a drum comprising perforated side walls and having a capacity of between 5 and 50 liters for each kg of fabric in the washload, wherein the solid particulate cleaning material comprises a multiplicity of non-polymeric particles at a particle to fabric addition level of 0.1:1-10:1 by mass, each of the particles being substantially cylindrical or spherical in shape, and wherein the drum comprising perforated side walls is rotated at a speed which generates G forces in the range of from 0.05 to 900 G. The non-polymeric particles may comprise particles of glass, silica, stone, wood, or any of a variety of metals or ceramic materials. Preferably the solid particulate cleaning material additionally comprises a multiplicity of polymeric particles each of which is substantially cylindrical or spherical in shape. Preferably, at least one detergent is employed in the cleaning process. The invention provides optimum cleaning performance as a result of improved mechanical interaction between substrate and cleaning media and is preferably used for the cleaning of textile fabrics. The method allows for significant reductions in the consumption of detergents, water and energy when compared with the conventional wet cleaning of textile fabrics, and also facilitates reduced washing-related textile fabric damage. The invention also envisages a cleaning composition comprising a solid particulate cleaning composition and at least one additional cleaning agent.
    • 本发明提供了一种用于清洁脏污基材的方法,所述方法包括用非聚合物固体颗粒清洁材料和洗涤水处理基材,所述处理在包括鼓的设备中进行,所述鼓包括穿孔侧壁并且具有 对于洗涤负载中的每kg织物,容量在5和50升之间,其中固体颗粒清洁材料包括多个非聚合物颗粒,颗粒与织物添加量按质量计为0.1:1-10:1, 所述颗粒基本上为圆柱形或球形,并且其中包含穿孔侧壁的所述滚筒以产生0.05-900G的G力的速度旋转。所述非聚合物颗粒可以包含玻璃,二氧化硅, 石头,木头或任何各种金属或陶瓷材料。 优选地,固体颗粒清洁材料另外包含多个聚合物颗粒,每个聚合物颗粒基本上为圆柱形或球形。 优选地,在清洁过程中使用至少一种清洁剂。 本发明由于改善了基底和清洁介质之间的机械相互作用而提供了最佳的清洁性能,并且优选用于清洁织物。 与传统的织物湿法清洗相比,该方法可显着减少洗涤剂,水和能量的消耗,并且还有助于减少与洗涤有关的织物损伤。 本发明还设想了包含固体颗粒清洁组合物和至少一种附加清洁剂的清洁组合物。
