This is a one-pot reaction yielding five new substances, represented by structures 1, 2a, 2b, 3a, and 3b. BASF has no commercial intent to separate any one species from the mixture. The amount of Lutropur® MSA affects the outcome of the reaction and which of the 5 species (1, 2a, 2b, 3a, or 3b) will be produced. When all 5 new substances are presented, they can be represented by a single CAS#. For ES 9057, the mole ratio of methanesulfonic acid to the trisodium salt of MGDA (Na3MGDA) is 1.2463 to 1.000. At this ratio there would be at most only a very small amount of Na3MGDA in the solution. The predominant species would be 1 (refer to the attachment "Chemical Structures"), with smaller amounts of 2a and 2b, and still smaller amounts of 3a and 3b. See the five different possible structures in the attachement "Chemical Structures". Processing Instructions file is also attached below.

The residual ES 9057 is estimated to be less than 0.1 % of the volume of the processing vessel. Another batch of the same product, if needed, would be made in the processing vessel without rinsing or otherwise cleaning the processing vessel of the residue of ES 9057. Furthermore, since other cleaning formulations are processed in the same processing vessel and the residue of ES 9057 is relatively small, the other cleaning formulations would be made in processing vessel in the presence of the residual ES 9057. Thus it is unlikely that a waste stream of rinsed ES 9057 from the processing vessel would be generated.
