摘要： A free-flowing granular detergent component comprises a high level (at least 30 wt %) of a heat-sensitive surfactant, preferably an alkyl ether sulphate; a water-insoluble silica or silicate carrier material of high oil absorption capacity; and a film-forming or crystal-forming structurant. The granular component may be used in conjunction with one or more other granular components containing surfactant and/or detergency builder, to form a particulate laundry detergent composition. The granular component is preferably prepared by mixing and granulation in a high- or moderate-shear mixer and drying in a fluidized bed.

摘要： A process for the preparation of detergent granules, the process comprising: (i) a first step of admixing in a mechanical granulator, an aluminosilicate and a first liquid binder comprising at least one surfactant, to produce a powder; and (ii) a second step of admixing in a low shear granulator, the powder produced in step (i), a water soluble salt and a second liquid binder, to produce the said detergent granules; wherein in step (ii), no more than 2%, preferably 0% by weight of the aluminosilicate based on the weight of the detergent granules is introduced into the low shear granulator of step (ii).

摘要： A process for the preparation of detergent granules, the process comprising: (i) a first step of admixing in a mechanical granulator, a solid component and a first liquid binder, to produce a powder; and (ii) a second step of admixing in a low shear granulator, the powder produced in step (i), and a second liquid binder, to produce the detergent granules; the second liquid binder having a different composition from the first liquid binder and the weight ratio of the first liquid binder to the second liquid binder being from 15:1 to 1:1, preferably from 10:1 to 1:1, more preferably from 5:1 to 1:1, most preferably from 3:1 to 2:1.
