ABSTRACT:
The trialkali metal salts of nitrilotriacetate are well known detergent builders. However, when hypochlorite bleach is added to the wash water it can oxidize the soluble uncomplexed nitrilotriacetate with the resultant loss of the beneficial effects of the use of such salts as a builder. Now, a method has been developed of protecting the desirable builder properties of the trialkali metal nitrilotriacetate in an aqueous solution containing active chlorine which comprises adding to the nitrilotriacetate a sufficient amount of trialkali metal imidodisulfate to protect at least some of the nitrilotriacetate from damage by the chlorine.
