Basically, silicones that are or are intended to have contact with food must meet the following specifications:
1) Silicones have to transfer their constituents to foods in quantities that can harm people's health and cause an unacceptable change in the composition of the food or alter the characteristics organoléticas of it.
2) They must be manufactured according to a System for Quality Assurance (ISO 9002 for example) and under the terms set forth in facilitated in the listing document of the Resolution (substances, and authorized additives).
3) The interaction between the substances for the manufacture of silicones should not generate substances that cause damage in people.
4) To prevent the formation of cyclic polydimethylsiloxane with phenyl groups, can not be used as the starting substances, which have linear siloxanes and phenyl methyl groups in the same atom or containing two methyl groups on the same silicon atom (siloxanes and silicones, methyl, phenyl, dimethyl).
5) The migration / emission of any substance from the silicone into the food has to be as low as technically possible. The total quantity of substances that may migrate is 10 milligrams per square decimetre area of material or 60 milligrams per kilogram of food. This is considered as the limit of global migration and coincides with the limit imposed by the directive on plastics in contact with food.
6) It should meet the specific migration limits specified in the technical paper of the resolution on silicones.
7) Migration tests must be carried out following the directions of the Directives 82/711/EEC, 85/572/EEC, 2002/72/EC and its future amendments unless it is technically impossible because of the nature Material and the migration test.
8) It must ensure a proper labeling of the product, if necessary, pre by the user.
In the case of children's products made with silicone and intended to come into contact with food, as in the example of teats for a bottle, also has to comply with specific regulations, especially regarding the content of volatile metal migration and specific migration of certain antioxidants.
