Detergent particles coated with precipitated calcium carbonate

The present disclosure relates to the use of precipitated calcium carbonate as a flow promoter in forming free-flowing detergent particles. A solid detergent composition comprising a plurality of detergent particles is provided. Each of the detergent particles comprises: a) a base particle comprising one or more surfactants; and b) a coating over the base particle, while the coating comprises precipitated calcium carbonate. The solid detergent composition is characterized by a surfactant content in the range of from 5% to 80% and a precipitated calcium carbonate content in the range of from 0.1% to 10%, based on the total weight of the solid detergent composition. 本公开涉及沉淀碳酸钙作为流动助剂在形成自由流动洗涤剂颗粒中的用途。提供了一种包含多个洗涤剂颗粒的固体洗涤剂组合物。该洗涤剂颗粒中的每个洗涤剂颗粒包含：a)包含一种或多种表面活性剂的基础颗粒；和b)位于该基础颗粒之上的涂层，同时该涂层包含沉淀碳酸钙。该固体洗涤剂组合物的特征在于按该固体洗涤剂组合物的总重量计，在5％至80％范围内的表面活性剂含量和在0.1％至10％范围内的沉淀碳酸钙含量。
