The Swiss List of Permitted Substances for the Production of Printing Inks and Requirements for These Substances (Annex 10) specifies the chemicals allowed for ink production, ensuring their safety and compliance during use. The list details all the chemicals permitted for ink production, including pigments, solvents, and additives. This list is designed to ensure that the ink components used in food contact materials do not pose a risk to consumer health. Substances included in the list are permitted for use in printing inks for food contact materials in Switzerland, but must also meet the corresponding requirements.
