摘要： A particulate detergent composition, preferably of relatively high bulk density, comprises agglomerate particles of clay, such as bentonite, and anionic synthetic organic detergent, of particle sizes in a certain desired range, with each particle thereof comprising individual particles of such clay of a smaller size and anionic detergent absorbed into said particles, on the surfaces thereof and between them, whereby a relatively high bulk density fabric softening detergent composition is obtainable. Such detergent composition is very desirably manufactured by a process in which bentonite or other suitable clay powder is agglomerated into detergent composition particles of desired size by agglomerating such powder with an aqueous medium containing a detersive proportion (for such detergent composition or for a built laundry detergent composition which may be made from it) of anionic synthetic organic detergent, in a process in which excess water from such aqueous medium, which could cause the agglomerate to be sticky and poorly flowing, is removed from the surfaces of the agglomerate particles by absorption, hydration and/or drying during and/or after the agglomeration process. The agglomerate particles are useful in making built detergent compositions by being blended with particulate builder particles, which are often spray dried and can be of relatively high bulk density too.

摘要： A water-soluble diammonium compound, such as N-methyl-N-(2-hydroxyethyl)-N-tallowalkyl-N'-methyl-N'-bis(2-hydroxyethyl)-propylene-diammonium methosulfate, is homogeneously and finely dispersed in a spray-dried detergent bead or granule. The spray-dried bead is blended with a clay mineral fabric softener. The final composition exhibits antistatic action even at low levels (e.g. less than 2%) of the antistat without adversely effecting softening, cleaning or whitening. In a typical formulation, the spray-dried beads include linear alkyl benzene sulfonate or other anionic surfactant, an inorganic polyphosphate and/or other inorganic and/or organic detergent builder salt, diammonium compound antistatic agent, and other heat stable and pH insensitive detergent additives and fillers. In addition to a smectite clay fabric softener, other post-added ingredients typically include a nonionic surfactant, enzyme, perfume, bleach, and other detergent additives which may be pH sensitive, heat sensitive, water-insoluble, or reactive with one or more of the components of the spray-dried beads.
摘要翻译：水溶性二铵化合物如N-甲基-N-（2-羟基乙基）-N-牛脂烷基-N'-甲基-N'-双（2-羟基戊基） - 丙烯二铵甲基硫酸盐是均匀且精细的分散在喷雾干燥的洗涤剂珠粒或颗粒中。将喷雾干燥的珠粒与粘土矿物织物柔软剂混合。最终组合物甚至在抗静电剂的低水平（例如小于2％）下也表现出抗静电作用，而不会不利地影响软化，清洁或增白。在典型的配方中，喷雾干燥的珠粒包括直链烷基苯磺酸盐或其它阴离子表面活性剂，无机多磷酸盐和/或其它无机和/或有机洗涤剂助洗剂盐，二铵化合物抗静电剂和其它热稳定和pH不敏感的洗涤剂添加剂和填料。除了蒙皂石粘土织物柔软剂之外，其它后加成分通常包括非离子表面活性剂，酶，香料，漂白剂和其它洗涤剂添加剂，其可以是pH敏感，热敏性，水不溶性或与一种或多种喷雾干燥珠粒的成分。
