I'# the Cosmetic, Toiletry and Fragrance Association, Inc. 1626 EYE STREET, N.W., WASHINGTON, D. C. 20006 202/383-2070 Mr. C.U. Driscoll President : Whittaker, clajck & Daniels, Inc. 1000 Collidge Street j ;South Plainfield, New Jersey 07080 The FDA, Mr. Driscoll -- James H. Merritt P fe & Id e n t Norman F. Estrln, Ph.D. -- has informed us that they are about to publish limits for as bestos in foods and will utilize an optical microscopy method for the determination. - Their problem is that the Bureau of Foods has been considering an X-ray diffraction method for cosmetic analysis of asbestos that has a sensitivity of one to two percent, as opposed to the claimed sensitivity microscopic method of 0.001 to 0,1 percent. FDA does not feel it can publish two different methods of dif fering sensitivities and has asked our cooperation in testing their optical method. FDA proposes that cosmetic manufacturers test and submit coded data for various cosmetic grade talcs, so that they can check on the validity of the method and get a feel for the type of results which can be expected. I have attached a copy of the method for your review and a copy of a letter from Heinz J. Eiermann (FDA) requesting assistance from the Cosmetic Industry. If you would like to participate by testing talcs, please drop a note to me or to Mr. George Sandland (Bristol-Myers) who is chairing a subcommittee which will test this and other methods. Thank you for your cooperation. Cordially, Norman F. Estrin, Ph.D. Vice President - Science N F E :jj September 13th, 1973 Attachments - 2 PLAINTIFFS EXHIBIT WCD-139 Goodhue WCD 000076
