Composite detergent particles and laundry composition comprising composite detergent particles

The invention relates to a composite detergent particle and a laundry composition comprising the same. A laundry detergent composition may be a composite detergent particle having a core particle covered by a coating, the laundry detergent composition may be a particulate detergent composition. The core particle comprises a mixture of silica, a C10 to C20 linear alkylbenzene sulfonate (LAS), and optionally a C10 to C20 linear or branched alkyl ethyoxyl sulfate (AES). And the coating comprises AES. Such composite detergent particles are characterized by high surfactant activity, improved water hardness resistance, rapid surfactant release and excellent dissolution properties. 本发明涉及复合洗涤剂颗粒和包含复合洗涤剂颗粒的衣物洗涤组合物。所述复合洗涤剂颗粒具有由涂层覆盖的芯颗粒，所述衣物洗涤剂组合物可以是颗粒状洗涤剂组合物。所述芯颗粒包含二氧化硅、C10-C20直链烷基苯磺酸盐(LAS)和任选的C10-C20直链或支链烷基乙氧基硫酸盐(AES)的混合物。所述涂层包含AES。这样的复合洗涤剂颗粒的特征在于高表面活性剂活性、改善的水硬度耐受性、快速的表面活性剂释放和优异的溶解特性。
