Process for making particulate laundry additive composition

摘要

A process for producing a particulate laundry additive composition for perfume delivery primarily in laundry detergent and fabric softening products is disclosed. The aforementioned needs in the art are met by the present invention which provides a process for producing a particulate laundry additive composition for perfume delivery primarily in laundry detergent and fabric softening products. The process essentially includes the steps of inputting an aqueous mixture a first encapsulating material and porous carrier particles (e.g., zeolite X) into an extruder, and thereafter, extruding the first encapsulating material, which is preferably a glassy carbohydrate material, with porous carrier particles, preferably loaded with a perfume, so as to form a hot extrudate. Subsequently, the steps of cooling and grinding the extrudate into granules is completed. In the final step, a second encapsulating material is coated onto the granules to enrobe further the perfume in the carrier particles.
