    • A laundry additive particle having multiple coatings and compositions employing the particle are provided. The laundry additive particle comprises a central core particle with the core particle comprising a porous carrier core material and a glassy encapsulating material intermixed with the carrier material. The glassy encapsulating material is derived from one or more at least partially water-soluble hydroxylic compounds having an anhydrous, nonplasticized, glass transition temperature, Tg, of at least about 0° C. An optional intermediate encapsulating material may be coated on the central core particle. The intermediate encapsulating material may comprise a carbohydrate material having an anhydrous nonplasticized, glass transition temperature, Tg of at least about 130° C. Lastly, an external coating material is coated on the core particle or the intermediate encapsulating material which provides the laundry additive particle with a substantially non-tacky surface. The external coating material is derived from one or more at least partially water soluble or dispersible compounds selected from the group consisting of waxes, water-soluble polymers, fatty compounds, carbohydrates, cellulose and cellulose derivatives, natural and synthetic gums, silicates, borates, phosphates, chitin and chitosan, and mixtures thereof. 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.
    • 提供了具有多个涂层和使用该颗粒的组合物的洗衣添加剂颗粒。 洗衣添加剂颗粒包括中心核心颗粒,其中芯颗粒包括多孔载体芯材料和与载体材料混合的玻璃状封装材料。 玻璃状包封材料衍生自具有至少约0℃的无水,未增塑的玻璃化转变温度Tg的一种或多种至少部分水溶性羟基化合物。可选择的中间封装材料可以涂覆在中心芯 粒子。 中间包封材料可以包含具有无水未增塑的玻璃化转变温度,至少约130℃的Tg的碳水化合物材料。最后,将外部涂层材料涂覆在提供洗衣添加剂颗粒的芯颗粒或中间包封材料上 具有基本上非粘性的表面。 外部涂料衍生自一种或多种至少部分水溶性或可分散的化合物,其选自蜡,水溶性聚合物,脂肪族化合物,碳水化合物,纤维素和纤维素衍生物,天然和合成树胶,硅酸盐,硼酸盐, 磷酸盐,几丁质和壳聚糖,及其混合物。 洗衣添加剂颗粒的吸湿性值小于约80%。 优选地,诸如香料的衣物或清洁剂被支撑在或包含在多孔载体中。
