Abstract
A process for producing a particulate laundry additive composition produces a particulate laundry additive for perfume delivery in laundry detergent compositions, especially those in the form of granules or agglomerates. The process includes mixing a porous carrier material, typically containing perfume, and an encapsulating material, typically a carbohydrate material, to form agglomerates or an extrudate which is then sized into particles for incorporation into a detergent product. The process may be employed to produce particulate additive compositions which may be used in fabric softening and dishwashing as well as laundry detergent compositions.
