Someone wrote about bullshiters ? ... Richard has repeatedly mentioned he is not aware what is in AG-Guard ... Ryuji responded to the effect that he even knew as much as the patent number... Subesquently, I belive Richard and I both asked him for it but I do not recal any forthcomming response.... therefore, Here is the CAS for the active ingredient... CAS# 25985-57-3 which is used in a concentration of 1% (plus or minus a half percent)... for the stock solutuion. I belive this would be 2-amidininosulfanyl-etansulfonat (C3H8N203S2) but I have not confirmed this. There may be a spelling problem.... When I locate the patent I will post that info too, if anyone is interested.
