FEDERAL SECURITY AGENCY FOOD AND DRUG ADMINISTRATION WASHINGTON 25. D. C. JUN 2 9 1949 Dr. William E. McCormick Department of Industrial Hygiene and Toxicology The B. F. Goodrich Company Akron, Ohio Dear Dr. McCormick: This acknowledges your letter of June 23 in which you present the results of the solubility studies on films 012212 and 012220G. Since no chloride or nitrogen was found in the extractable material it is probably reasonable to assume that the extractable is composed largely of glycerol mono-oleate and acrawax. Under these circumstances we can see no objections to the use of the above films for food packaging purposes. Very truly yours. Chief, Div. of Pharmacology BFG03565 20465001
