Abstract : Anticipating a concerted effort to greatly reduce or eliminate phosphate in detergents and other cleaners, an initial study was made of the feasibility of substituting organic chelates for the phosphates in steam cleaners covered by Federal Specification P-C-437. This preliminary investigation indicates that phosphate-free compositions meeting P-C-437 requirements can be made by substituting for the phosphates various combinations of organic chelates with the incorporation of a hydrotrope.
