  A detergent composition having a phosphorous content of no more than 6 % and a solution pH of less than 10 contains an organic detergent, a carboxylate builder having a pK, of less than 9 and a small amount of a polyphosphonic acid. Typical compositions utilise a citrate or succinate builder together with ethylene diaminetetramethylene phosphonate. The compositions are particularly effective in the area of bleachable stain removal.

  一种磷含量不超过 6%、溶液 pH 值小于 10 的洗涤剂组合物含有一种有机洗涤剂、一种 pK 值小于 9 的羧酸盐促进剂和少量的多膦酸。 典型的组合物使用柠檬酸盐或琥珀酸盐促进剂以及乙烯二胺四亚甲基膦酸盐。 这种组合物在漂白去污方面特别有效。
