GRANULAR DETERGENT COMPONENTS AND PARTICULATE DETERGENT COMPOSITIONS CONTAINING THEM |
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 fluidised bed.
