A process for producing a particulate laundry additive composition for perfume delivery primarily in laundry detergent and fabric softening products is disclosed. The process essentially includes the steps of drying an aqueous mixture of a pigment and an encapsulating material to form a fluid that preferably is devoid of water or at least has a portion of the water evaporated by this drying step, and thereafter, extruding an encapsulating material, 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 particles is completed. |
