I found hints to the ingredients in ACS 200, which Frank tested to be 60PPM and 81% ionic: http://www.silver-colloids.com/Reports/ACS200/ACS200.html
ACS 200 appears to be also sold as a sterilent: http://www.resultsrna.com/products/steriplex_health_care_now_epa_approved.php#.UPDE8azUkl8 And here is an MSDS for the sterilent called "Steriplex": http://www.steriplex.com/products/steriplex_hc_msds.php#.UPDE0KzUkl8 It contains an ingredient list. Whether or not the formulas are exactly identical I don't know. If anyone cares to discourse then on what ACS 200 actually might be, I would appreciate the thoughts. David
