BUn nenm m.himiot t SPI Food, Drug and Cosmetic Packaging Materials Committee Re: GRAS Comments and Dutch Regu­ lations for Food Additives Gentlemen: In our recent GRAS comments we proposed that incidental additives, with certain exceptions such as heavy metals and the like, should be considered GRAS if the migration of such addi­ tives was sufficiently low (we proposed .5 parts per million as the cut-off point). It is in­ teresting, that shortly after we filed these comments, we received through the very great courtesy of Dr. J. H. DeWilde of Shell in The Hague an amplification and more detailed explana­ tion of the Dutch "new look" in food packaging regulations which, in effect, seems aimed at achieving a very similar end result. You may recall that at our last meeting Bob Miller of Hercules reported on the new Dutch proposals for dealing with the question of inci­ dental food additives. A summary of Bob's pre­ sentation was sent to Dr. DeWilde and he has very kindly sent to us a copy of his letter to Bob Miller which amplifies and clarifies the Dutch "new look." Not only are we being provided with Dr. DeWilde's very careful explanation of the thinking that went into this "new look," but he also included copies of a paper which was presented in Rome by Dr. D. G. Aldershoff which also discusses the "new look." Included with Dr. Aldershoff's paper are two attachments—Annex A which is a sample regulation for polystyrene ASI-PR 0001410 June 22, 1972 Page Two (in English translation), and Annex B for glass and glass-based ceramics (in French). As you review the enclosures you will note that the Dutch government is directing its concern to the quantity of a substance that might actually migrate to a packaged food—not to how much is put into the packaging material. In order to be practical and minimize unnecessary work, the government arbitrarily set a figure of 60 (mg/day, ppm)!/ as the maximum amount of any indirect additive (except selected plasticizers) that will be permitted to enter the food of an average consumer regardless of how safe or inert it might be. Based upon toxicological testing on animals and the use of appropriate safety fac­ tors, a packaging acceptable daily intake (PADI) is established for each substance permitted in a packaging material and a list of substances with its PADI is prepared. Any substance whose PADI is in excess of 60 mg will require no special considerations; but each substance whose PADI is below 60 mg will require specific analytical attention. The entire process requires that gross migration tests be conducted with foodsimulating solvents. If the total amount ex­ tracted is less than 60 mg/5 dm2 (or 6 dm2)!/ y Dr. DeWilde explains why 60 ppm in the gross extraction test is also equivalent to 60 mg/day intake of extractives. It should be noted, too,, that this reduces to 24 ppm in the whole diet, based upon the reasonable assumptions which were used. The maximum total surface of packaging material that might reasonably contact the total daily food intake of a consumer has been estimated by the Dutch to be 5 sq. decimeters, and by EEC person­ nel to be 6 sq. decimeters. In any case, the numerator then represents the maximum quantity y ASI-PR 0001411 June 22, 1972 Page Three then no specific tests will be required for any component whose PADI is above 60 mg, since the PADI of these substances cannot have been exceeded. However, those components whose PADI are below 60 mg must be given specific analytical attention; and no such substance may be present in an amount (in mg/5 dnr) that exceeds its PADI. Even this amount of work may be mini­ mized in some cases, since no specific tests are required for any substance whose PADI is above the gross extractives that are actually found. '■ J x3 \\ /j Finally, a modification of the Frawley doctrine is included in the scheme because additives migrating to an extent less than 0.05 mg/5 dm^ are exempted even though no toxicological data is available (unless government toxicologists consider that the structure makes such substances suspect). There can be controversy about some of the details of this "new look," indeed there is a difference of opinion between Dutch and EEC personnel regarding whether the area used for calculating migration should be 5 dm^ or 6 dm2; but the entire approach appears to us to be the result of considerable study. It very carefully balances toxicological con­ siderations against the amount of an additive that might enter the diet. It requires careful (and expensive) analytical work only ( ,tfor those cases where a health hazard could conceivably exist and would seem to signal a i ^ constructive move away from the devotion of time, effort, and money to those cases where there is no health problem. , 'j 1 2/ (cont'd) of total extractives that could enter a person's diet if everything he ate that could be packaged were packaged in the mate­ rial being considered. ASI-PR 0001412 June 22, 1972 Page Four While the adoption of a scheme such as the "new look" by the FDA would require a more extensive revision of the American regulatory scheme than seems politically possible in the near future, it is good to note that this very careful blending of law, science, and common sense is being implemented somewhere. The only thing missing from the infor­ mation we now have, and by this copy of this letter we are requesting Dr. DeWilde to please send us such additional information if he can do so, is an understanding of how new materials will be added to the Dutch regulations. In other words, what procedure should be followed if a manufacturer, supplier, or user wishes to have a new material added to the list in an existing regulation? Here in the United States, as you all well know, the petition-regulation procedure is quite complex and extremely time consuming; thus, it would be most interesting and valuable to us to learn how the Dutch are planning to handle this aspect of the regulatory problem. Wte hope you find this information as interesting as we did, and that it will prove to be a valuable guide to contemporary European thinking and practice in this area.

Miller Chairman of the SPI Food, Drug and Cosmetic Packaging Committee c/o Hercules Inc. 910 Market Street c Dear Bob, Somebody forwarded to me a copy of the summary of the speech you gave on the occasion of the SPI's Food, Drug and Cosmetic Packaging Committee*s meeting in the Shoreham Hotel on March 19th, 1972. In offering a few comments I would like to start with complimenting you with the excellent way in which you summarized the Dutch "new look", The new approach has not been invented merely to resolve the differences between the Latin and the German philosophy but in the first place because the old system is not susceptible to any control. In some countries such as the U.S.A., industry might be so lawful that every company will strictly adhere to the ' FDA-regulations, but one cannot assume that this ethical behavior is common to industry in every country. Our "new look", moreover, is directly correlated with the aspects of public health. Technological aspects which were a strong point in the old approach, have been omitted as much as possible, the philosophy being that the Government should not interfere with industry and the way industry wants to formulate food packaging compositions. Allowing 0,2% of a certain additive in, aay, PP has no correlation whatsoever with public health since the amount of the additive migrating into the packaged foodstuff depends to a very large extent on the composition of the PP film, its crystallinity, whether stretched and/or coated or not, etc. The "new look" speciflesi on account of public health considerations we don't want more than x mg per day of this additive to be ingested by the average Dutch­ man. */2 ASI-PR 0001414 I Dr. R.M. Miller Vilmingt n O.S.A. 9.6*1972 Industry Is free to use any quantity of that additive In their PP film, but they are responsible for ensuring that not more than x mg is consumed per day per person. The figure "x" is related to the "no-effect level" found In animal tests. Since 2-year tests with rats are needed to establish an ADI (FAO/WHO suggestion) and the Netherlands Government for obvious reasons agreed that 90-day feeding tests would suffice in the case of additives used in food packaging materials, we have denominated "x" as PADI (Packaging ADI). -s ^ 1 , c The only thing which is needed to make the "new look" work is to establish a PADI for each of the additives used and to develop analytical methods to assess quantitatively the specific migration of each migrating additive in foodstuffs. The first part has been accepted by the Council of Europe. The British Government representative, Dr. P. Ellas, insisted on establishing PADI's for each additive and Dr. G.J. van Esch (Dutch) has been charged in making "toxicological data-sheets" for each additive. He finished his commitment just before this month's meeting of the Council of Europe and will request the toxicologists of the other countries to fill in the gaps. The second part, the search for analytical methods is actively being pursued by analytical groups in the various countries. Several of the 24 communications given at the Rome symposium dealt with this subject. All vhn-fe has baen said and done in Rome has been collected JIA AUVQU Jp«II UUQ VvlUlttV • VVO iiclf« Ui uttUY UcuU requested xo indicate the number of copies we would Ilk to purchase but no price has been indicated as yet. There is one other thing that has worried me for the past few years and that seems near a solution now. The correlation between PADI and the amount of migrated additive (expressed in mg per dm2) has never been laid down. One of the reasons to accept 90-day animal feeding tests has been the Government assumption that the additive might be used in all packaging materials coming In contact with our dally food. This was assumed to be $ dm2 _Dfi3C-dav (Council of Europe 6 dm2 j Germany 10 dm2, U.S.A.30 dm2). There obviously may be a difference in migration.into aqueous and into fatty foodstuffs. Taking this into account would Involve a system of "food factors” 3Dr. R.M. Hiller Wilmington U.S.A. v. 9*6.1972 which, however. Is less suitable for harmonisation. Ve therefore suggested quite recently to abandon "food factors" and to multiply the number of mg per dm2 of migrants with six. Food simulants are usedi distilled water. 3% acetic acid. 10% ethanol and arachls oil. coconut oil or the Unilever synthetic fat HB 307. Conditions of temperature and time should be chosen as closely as possible approaching actual conditions. Since it has been demonstrated that the migration approaches the asymptote in 6 - 8 days, the testing period not necessarily should exceed, say, 10 days. The French law still demands 30 days; even the not yet published new "directive for applying approval etc.". To limit the amount of work, the arbitrary number of 60 has been accepted. To the French and Italians this means the limit where above the food will be considered contaminated. To the Dutch it means that no PADI has to be calculated of additives that can be consumed in larger quantities than 60 mg per day. There consequently is no need for policing these as long as the "gross migration" is lower than 60 mg per 3 dm2 (6 dm2). In the case of plastics this is always so except for plastics containing plasticizers. A total quantity of 100 ppm of defined plasticizers on the packaged food parcel is allowed. Whether this figure will be maintained in the future remains to be seen since plasticizers may not be always that safe. Additives migrating less than 0,03 mg per 9 dm2 are exempted (Frawley doctrine) even although no toxicity data are known (except when their structure seems suspect to our Government toxicologists). The figure of 9 dm (6 dm to follow the Council of Europe*s advise) has been accepted as the average surface coming into contact with the 1 kg non-dry packed food consumed daily per person. t Please,find attached the communication Dr* Aldershoff submitted at the Rome symposium. Included as annexe "A" is the English translation of schedule 2s polystyrene mixed and copolymers. You will note that only a few additives have to be policed which makes the whole scheme workable. The control laboratory will first make a ^qualitative analysis of the packaging material to assess which additives are present and whether the -A ASI-pR 0001416 Dr. R.M. Killer Wilmington D.S.A. 9.6.1972 composition complies with the "positive list". Only for reasons of easier control we adhere to separate lists for each separate type of plastics - otherwise one could accept the alphabetical Italian list. c B.I.T.M.P. and S.I.I.C* are making an attempt to convince the Council of Europe that a) monomers are different from additives in that they are reactive and their presence in the end-product can be expected in exceptional cases only that can be listed or regulated) b) process chemicals are used in small quantities, will partly break-down or combine with the polymer so that their specific analysis in the migrate is not needed. If Governments want to play safe, analysis of groups' (e.g. peroxides) or heavy metal traces can be Incorporated. Annexe "B" shows that the same system works with glass. We have almost finalized paper and board, elastomers, glass, ceramics, metals and are now working on a "coating list". I cannot support your statement that the Netherlands' ■new look" will not be of much help to you in your negotiations with FDA. In contrary, this "new look" may offer you an unique opportunity to get your FDA system changed and simplified, to the benefit of both public health and industry! c I apologize if I have not been able to make the essentials of the "new look" clear in this letter; a ersonal discussion would be much more efficient. o you plan to visit the Netherlands in the near future?
