ABSTRACT:
Solutions comprising at least one polyamino disuccinic acid and one or more polyamino monosuccinic acids are useful in gas conditioning (preferably as the iron chelate). The copper chelates are also useful in electroless copper plating. Another aspect of the invention includes the use of the aminosuccinic acid mixtures in laundry detergent compositions.
