' ' ' . Subjects Talc Toxicity Data . ' Your letter of August 23, 1971, was duly received. Please pardon the delay in answering as we are shorthanded right now due to vacations. We have considrable data on the use of talc in products coming in contact with foods. Bncloaed is a copy of our memorandum dated May 22, 1970, which lists the products in which talc may bo used as a "safe substance."-- You will note that the list shown therein does not Include talc for use in plastic products coming in contact with food. Lant year we exchanged correspondence with the PDA relative to having talc declared as a safe substance In plastic. I am enclosing copie of letters dated February 6. 1970; April 16T 197: Anrll 21. 1970: and June 2. 1970. W have heard of no changes in clasalflestions or end use approvals since thejabove mentioned dates. However, ve do receive cbpi.es of all PDA bulletins and try to maintain a complete file. The general provisions of the Pood Additives Regulations requiring substances to be of n purity suitable for their intended use Is also recognized by us. However, as a raw mater ial supplier, we must rely on the user to supply ua with specifications which will cover FDA requirements. We see no reason why the use of talc in plastic products coming in contact with food should not be accepted as a safe substance considering the fact that it : already approved for use in rubber, paper, cotton, and paint products coming in contact with; food. Furthermore, we do(not think* there would be any migration of the talc from a plastic container into the food. - , .; \ ' . - More specifically: answering your three questions, replies are as follows to det- j th presence of any; minor elements otheKthan theoretically: pure magnesiust silicate, talcy As this work is completed;va shall be glad;to reply more specificallyi In the meuntime, please advise us if possible, under what goverriinaht regulations these minefaifl are referred to.
