    摘要: A laundry additive particle having multiple coatings and compositions employing the particle are provided. The laundry additive particle comprises a porous carrier core material; a first encapsulating material coated on the core material to form an intermediate layer, the first encapsulating material comprising a glassy material derived from one or more at least partially water-soluble hydroxylic compounds having an anhydrous, nonplasticized, glass transition temperature, T.sub.g, of at least about 0.degree. C.; and a second encapsulating material coated on the intermediate layer to form an outer layer, the second encapsulating material comprising a carbohydrate material having an anhydrous, nonplasticized, glass transition temperature, T.sub.g, of at least about 130.degree.0 C.; and the laundry additive particle has a hygroscopicity value of less than about 80%. Preferably, a laundry or cleaning agent such as a perfume is supported on or contained in the porous carrier.

    摘要: 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.
