    • A process for washing textiles is presented involving the delayed release of ingredients from a detergent composition. The process involves first dissolving the detergent in water resulting in a pH below pH 8, slowly dissolving the coating on a coated alkalizing agent to raise the pH to above pH to above pH 8.5, and above pH 8.5 the polymeric acid coating on a detergent ingredient dissolves, releasing the ingredient into the wash water. Also presented is a detergent composition for delayed bleaching of 1 to 40 percent by weight of a coated bleaching agent having a coating which dissolves slowly in water irrespective of the pH value, 0.5 to 15 percent by weight of a bleach activator coated with a polymeric acid, and 0.1 to 40 percent by weight of an acidifying agent. The process results in a delayed release of bleaching in the wash cycle.
    • 提出了一种用于洗涤织物的方法,涉及从洗涤剂组合物中延迟释放成分。 该方法包括首先将洗涤剂溶解在水中,使pH低于pH8,缓慢地将涂层溶解在包衣的碱化剂上,使pH高于pH8.5,高于pH8.5,洗涤剂成分上的聚合酸涂层 溶解,将成分释放到洗涤水中。 还提出了一种洗涤剂组合物,用于延迟漂白1至40重量%的涂层漂白剂,其具有在pH值范围内缓慢溶解在水中的涂层,0.5至15重量%的涂覆有聚合酸的漂白活化剂 ,和0.1〜40重量%的酸化剂。 该过程导致漂洗在洗涤循环中的延迟释放。
