    • The present invention relates to a method for making a laundry detergent particle comprising from 10 to 60 wt % (anhydrous basis) zeolite, from 12 to 75 wt % polycarboxylate polymer, and optional additional ingredients to 100% by weight, said method comprising preparing an aqueous slurry comprising zeolite, and polycarboxylate polymer and optional additional ingredients and spray drying the slurry. The weight ratio of zeolite (anhydrous basis) to polycarboxylate polymer in the slurry is from 4:1 to 1:2. The particles have been found to reduce caking of detergent product whilst providing improved cleaning compared with the addition of the polycarboxylate polymer as a separate granule. The invention also includes detergent compositions comprising such particles. The particles may be incorporated into a finished detergent composition as part of an agglomerate or extrudate.
    • 本发明涉及一种制备衣物洗涤剂颗粒的方法,其包含10至60重量%(无水基)沸石,12至75重量%多羧酸盐聚合物和任选的附加成分至100重量%,所述方法包括制备 包含沸石的含水浆料和聚羧酸酯聚合物和任选的附加成分并喷雾干燥浆料。 沸石(无水基)与浆料中多羧酸盐聚合物的重量比为4:1至1:2。 已经发现,与作为单独颗粒添加聚羧酸酯聚合物相比,已经发现这些颗粒减少洗涤剂产品的结块,同时提供改进的清洁。 本发明还包括包含这种颗粒的洗涤剂组合物。 颗粒可以作为附聚物或挤出物的一部分掺入成品洗涤剂组合物中。
