General rules and regulations
European Union (EU)
At European level, the general requirements for the safety of food contact materials and articles are laid down in the so-called Framework Regulation (EC) No. 1935/2004. The manufacturer of the material or article is responsible for the conformity of the final product with the provisions in Article 3.
According to Article 3, food contact materials and articles shall not, under normal or foreseeable conditions of use, transfer substances to food that are suitable,
- endanger human health,
- bring about an unacceptable change in the composition of the food; or
- cause an impairment of the smell, taste, texture or appearance of the food (so-called organoleptic properties).
In addition to the overarching EU Framework Regulation, manufacturers of consumer goods must comply with many other regulations, such as the requirements for good manufacturing practice (GMP) (Regulation (EC) No. 2023/2006) or individual material-specific measures, such as Regulation (EU) No. 10/2011 for plastics.
Germany
The European requirements have been largely integrated into national laws. The German counterpart to the EU Framework Regulation is the "Lebensmittel-, Bedarfsgegenstände- und Futtermittelgesetzbuch (LFGB)". This replaced the old Foodstuffs and Consumer Goods Act (LMBG) in 2005 and is the umbrella law for German food law. Article 3 of the EU Framework Regulation was incorporated here, for example, in §31, para. 1.
BfR recommendations
The Federal Institute for Risk Assessment (BfR) develops recommendations within the framework of the German "Food, Commodities and Feed Code (LFGB)", which can be found in the database "BfR Recommendations on Food Contact Materials" (formerly "Plastics Recommendations").
The BfR recommendations on food contact materials do not constitute legal standards. However, they are based on the European legal situation and its implementation in national law and reflect the current state of science and technology. They are therefore nevertheless an important and accepted guide to deriving whether a food contact article meets the legal requirements of the EU Framework Regulation (EC) No. 1935/2004 or the LFGB. The BfR recommendations are particularly important for food contact materials that have not been specifically regulated at EU level to date, such as silicones, paper and rubber.
USA / FDA
The aim of the US Food and Drug Administration (FDA) is to ensure safe food. Title 21 of the Code of Federal Regulation (CFR) lists all substances permitted for contact with foodstuffs as determined by the US authorities. These positive lists contain substances that are suitable for contact with food. In contrast to the EU, the positive lists and the exact requirements therein are very material-specific.
It is assumed that in principle all components of a material can migrate into food. Therefore, all materials and ingredients are referred to as "indirect food additives".
Title 21 is divided into chapters (Parts). Relevant for food contact materials are Parts 170-190, which are further subdivided. In these paragraphs, the requirements for the respective material for food contact are regulated. These requirements refer on the one hand to the ingredients in the material and on the other hand also to further, additional requirements.
In addition, substances from the so-called GRAS lists ("Generally Recognized As Safe"; Parts 182-184) or so-called "Prior-Sanctioned Food Ingredients" (Part 181) can be used as additives for all food contact materials at any time.
Plastics
EU regulations
Within the framework Regulation (EC) No 1935/2004 there are some specific measures on certain materials. One of these individual measures is Regulation (EU) No 10/2011 on plastic materials and articles intended to come into contact with food. This regulation, also known as the PIM (Plastics Implementation Measure), replaces the former "Plastics Directive" (2002/72/EC). In the meantime, a number of corrections and amendments to this regulation exist.
When plastics come into contact with food, components of the plastics can migrate to the food. The aim is to exclude, as far as possible, a health hazard due to such migration.
For this purpose, Regulation (EU) No 10/2011 establishes a positive list (Union list) of monomers and additives that may be used in the manufacture of plastic food contact materials and articles. Components of the Union list do not include polymerisation aids (catalysts, accelerators, initiators, etc.) or colourants. For "polymer production aids" (PPA) the Union list is not comprehensive. Substances not covered by the Union list are subject to national legislation and recommendations (e.g. the BfR recommendations).
Before inclusion in the Union list, substances have to be tested for their possible transfers to food and their toxicological properties. Based on these results, upper limits of permitted migration into food are set for some substances, so-called "specific migration limits (SML)". For all substances for which no SML was set, a "general SML" of 60 mg/kg applied for a long time. However, this was abolished at the end of 2016 with the amending Regulation (EU) 2016/1416. For substances for which such a specific migration limit (SML) cannot be verified, there are also quantitative restrictions (maximum concentrations) in the material (QM) instead. This limits or excludes a transfer to food as a precautionary measure. An overall limit is set for the sum of all substances migrated into the food, the "overall migration limit (OML)". This OML is defined as 10 mg per dm2 of the food contact surface of the material, or 60 mg per kg of food.
Substances that have not been evaluated must not be detectable in food. The generally accepted and practicable detection limit of 10 ppb (0.01 mg/kg) is considered "undetectable" today. This limit is also set in the amending Regulation (EU) 2016/1416 in Article 11, paragraph 4.
Polymers and substances with a molecular mass greater than 1,000 Daltons generally have little to no migration potential. Furthermore, these substances are not absorbed from the gastrointestinal tract and therefore pose virtually no toxicological risk in the eyes of the European Food Safety Authority (EFSA). Consequently, polymers and substances > 1,000 Daltons also have no significance in the sense of EU regulations and national laws and recommendations.
National regulations
The German Consumer Goods Ordinance (BedGgstV) can be regarded as the national counterpart to EU Regulation No. 10/2011. The BedGgstV lists the substances that may not be used in the commercial manufacture or treatment of certain consumer goods (§3, Annex 1) or may only be present in food consumer goods up to a certain maximum quantity (§6, Annex 5). The transfer of substances from plastics into food is also regulated in the BedGgstV (§6).
BfR recommendations
The focus of the recommendations was originally in the area of plastics for food contact. However, harmonised legislation now exists for plastics at European level, such as Regulation (EU) No 10/2011 in particular, which largely regulates this area. Many of the substances originally included in the Plastics Recommendations were gradually incorporated into the Consumer Goods Ordinance or the Union List and subsequently deleted from the BfR Recommendations.
For this reason, the BfR recommendations in the area of plastics now only take into account those substances that are not or not exhaustively covered by the Union list of EU Regulation No. 10/2011. These include the "aids to polymerisation", which include the components of the catalytic system (catalysts and initiators), and the "polymer production aids" (PPA), which include, for example, emulsifiers that are required in the manufacturing process.
FDA
In Title 21 of the Code of Federal Regulation (CFR), Parts 177 and 178 are particularly relevant for plastics. Part 177 - "Indirect Food Additives: Polymers" lists the different types of polymers in individual paragraphs. The requirements for polyolefins, for example, are in §177.1520 and those for polyurethanes in §177.1680. In "Part 178 - Indirect Food Additives: Adjuvants, Productions Aids, and Sanitizers", various additives, adjuvants and auxiliary substances are described in corresponding paragraphs. For example, the relevant paragraph for antioxidants is §178.2010 and colourants are regulated in §178.3297. In addition, the substances listed in the GRAS paragraphs (Parts 182-184) and the "Prior-Sanctioned Food Ingredients" (Part 181) can of course be used at any time.
If an additive is not listed in the paragraph intended for the intended use, it is still possible to use it based on the "no-migration" principle. If FDA-recognised migration studies show that the substance concentration in the food is below 50 ppb in the desired application, this principle can be applied on the company's own responsibility. For packaging materials with a high market share and thus a high consumer exposure, a limit value of 10 ppb is recommended by the FDA ("consumption factor").
Why we cannot guarantee final compliance when using our additives in food contact materials...
The migration potential of a particular substance can depend on many different factors, including:
- the type of plastic / polymer,
- the properties of the food (e.g. dry, watery, sour, fatty),
- Interactions with other plastic additives,
- the ratio between packaging surface and volume.
Therefore, the final compliance with the legal requirements has to be done by the manufacturer of the final food contact material / article of daily use, taking into account the respective use and conditions of use. For this reason, we recommend carrying out migration tests on the final product to check and confirm compliance. Testing can only be dispensed with if a limit crossing can be excluded from the ratio of packaging to product mass when assuming complete migration of the migrant (worst case).

Lubricants
Lubricants can be used, among other things, as lubricants or as release agents in various components or machines (e.g. conveyor belts, seals, closures) which are used in locations where the lubricated component may come into contact with food. Since occasional, unintentional contact between lubricant and food cannot be completely ruled out, certain requirements must be observed and fulfilled.
For lubricants, the general rules and regulations apply in the EU and at national level, such as the EU Framework Regulation No. 1935/2004 or the LFGB (§31).
However, there are no specific EU regulations for food-grade lubricants - unlike plastics - and no specific national regulations either. For this reason, it is common to refer to the widely accepted US standards. In no other country are the legal regulations for the use of lubricants and lubricant additives as strict as in the USA.
FDA
In Title 21 of the Code of Federal Regulation (CFR), the FDA specifies which ingredients may be used for food lubricants. 21 CFR §178.3570 (Lubricants with incidental food contact) is particularly relevant in this regard. Additives for lubricants in contact with food must meet the requirements of this paragraph. In addition, as with plastics, the substances listed in the GRAS paragraphs (Part 182-184) can of course be used.
NSF certification according to H1 / HX-1
Until 1998, the United States Department of Agriculture (USDA) was responsible for the approval of food-grade lubricants. Since 1999, "NSF International" (National Sanitary Foundation) and "InS Services Ltd" have taken over this task.
A special lubricant for the food sector can only be approved if the requirements of the FDA are met. Depending on the requirements and specifications, the lubricants are divided into different classes. H1 lubricants ("Lubricants - General incidental contact") are of particular importance for the food sector.
The highest demands are placed on H1 lubricants. Only lubricants certified with H1 may be used at all points in the food, pharmaceutical and animal feed industries where incidental, technically unavoidable contact between the lubricant and the product may occur. The ingredients in H1 lubricants must be certified with HX-1 ("Ingredients for use in H1 lubricants - incidental contact"). Prerequisite for HX-1 certification is a listing in 21 CFR §178.3570 or a GRAS notification (Part 182 and 184). Otherwise, a time-consuming notification process is required.
We are pleased to announce that we have launched our product LUBIO® EP 3 successfully certified according to the standards of the NSF category HX-1.
