Liquid compositions containing a perborate bleaching system having improved chemical stability over existing systems are prepared by suspending a salt of a superperborate in a non-aqueous liquid. The superperborate salts have an available oxygen content of greater than 16.1%, and an empirical chemical formula of the type NaxByOz.nH₂O where x is 1-4, y is 1-5, z is 2-15 and n is 1-5. The ratio of x:y is between 0.5 to 1.2:1. The compositions may include surfactants, activators and detergent auxiliaries. Preferred surfactants are nonionic surfactants. When a surfactant is present, the compositions are bleach containing liquid detergents. When surfactants are not present, the compositions can be used as bleach additives or non-detergent cleaners.
通过将超硼酸盐悬浮在非水液体中,制备出含有过硼酸盐漂白体系的液体组合物,与现有体系相比,其化学稳定性有所提高。超硼酸盐的可用氧含量大于 16.1%,经验化学式为 NaxByOz.nH₂O,其中 x 为 1-4,y 为 1-5,z 为 2-15,n 为 1-5。x:y 的比例在 0.5 至 1.2:1 之间。组合物可包括表面活性剂、活化剂和洗涤助剂。首选的表面活性剂是非离子表面活性剂。含有表面活性剂时,组合物为含漂白剂的液体洗涤剂。不含表面活性剂时,组合物可用作漂白添加剂或非洗涤剂清洁剂。
