Monsanto Chf ical Company At Tiuj City, Teai Cat* Kay 29, 1958 c: P. C. Kelly Research file to Dr. R. ant Kelly *i St. Louis, Ho. feltieict Subitci Benzene In Polyethylene The plant has requested information on the amount of benzene that can be safely left In the polyethylene used In food packaging. At present the only available Information they have la that the fresh unrefined pellets contain 400-500 ppm of benzene and the refined pellets 50 ppm. Actually the above figures should probably be considered men leas since normal de gassing in 72 hours is approximately 50% and it will usually be several weeks before the material would reach a customers solding process. They have no information on how much la left in the polymer after it.passes through a molding machine but alr.ce the machines operate at 350*CT there shouldn't be njcn benzene left. Since the unrefined product is already on the market, their question now is vi.ether there is an acceptable limit already established for benzene In polyetnylene. They are rather late requesting this information but they neeoed to first obtain reliable information on the amount of benzene present. If re fining is necessary to reduce the level to 50 ppm the production coat will certainly be increased. Any further lowering would really get expensive. Vr.it is your opinion! la 400 ppa too high? If so, do you have any idea as to wnat would be acceptable? Also, do you need sere Information before giving us an answer? 1 H- X -n ~o nn rz z > r a >-* m - wo xm rrj o9 c> H rx M >z X "U <J\ co JS7/1 AKp C 3 2 S 7 i Iu '-Ci MONSANTO :s45UPA*C; orp.ury TREAT AS PROTECTED CyDER ATT'CRXTT tat 0 order protected material ?RTVI1LCE AOC VORX PRODUCT COCTRIST.
