COLGATE-PALMOLIVE COMPANY Research and Development Department 909 River Road, Piscataw ay, N. J. 08854 CHRISTOPHER H. COSTELLO. Ph. D. Administrator of Regulatory Affairs March 17, 1976 Mr. Heinz J. Eiermann, Director Division of Cosmetics Technology Bureau of Foods Food and Drug Administration 200 "C" Street, S.W. Washington, D.C. 2020^4 Dear Heins: I understand that you are planning to send the ?6 talc samples tested by FDA to Dr. Langer of M t . Sinai Hospital for examination under a code designation. You -will recall that one of the three Colgate samples which you picked up bore no identifying code number. We feel that sending an unidentifiable sample to Dr. Langer is not in the interest of good science, since we would be unable to identify the date of manufacture or source of raw material. We, therefore, respectfully request that if you feel you must send samples to Dr, Langer that the sample bearing no batch identification be omitted. We will also appreciate it if you can supply us with samples of the three Colgate samples and the one Rubinstein sample you have so that we can run analyses on the same containers as you did. Very truly yours, CHC/ed
