    • A method of treating a peroxygen compound (e.g., potassium monopersulfate) for use in applications where controlled release rate, exposure to incompatible compounds, and/or moisture is presented. The method incorporates coating the peroxygen compound with one or more of the following polymers: 1) chitin/chitosan, 2) carboxylate/sulfonate copolymer or tertiary polymer, and 3) carboxylate polymer selected from polymaleic acid, polyepoxysuccinic acid and/or phosphinocarboxylate polymers. Optionally, the peroxygen compound is also coated with an inorganic salt layer and a silicate layer. Potassium monopersulfate coated with an organic polymer is useful in reduced allergenic formulations and as an anti-caking agent. When the organic polymer is a polysaccharide, the coated potassium monopersulfate is also effective for shock treatment of water systems (e.g., pools). The oxidizing composition prepared with this method has a prolonged shelf life while demonstrating good solubility during use.
    • 提供了一种处理过氧化合物(例如单过硫酸钾)用于控制释放速率,不相容化合物和/或水分暴露的应用中的方法。 该方法包括用以下聚合物中的一种或多种涂覆过氧化合物:1)几丁质/壳聚糖,2)羧酸酯/磺酸酯共聚物或叔聚合物,和3)选自聚马来酸,聚环氧琥珀酸和/或膦酰基羧酸酯聚合物的羧酸酯聚合物。 任选地,过氧化合物也涂覆有无机盐层和硅酸盐层。 用有机聚合物涂覆的单过硫酸钾可用于还原过敏制剂和抗结块剂。 当有机聚合物是多糖时,涂覆的单过硫酸钾对于水系(例如池)的休克处理也是有效的。 用该方法制备的氧化组合物具有延长的保质期,同时在使用过程中显示良好的溶解性。
