The new products – which include a yellow, a red and two blues – are optimised for use in tissue grade papers for products like napkins.
Ian Jewell, head of the Swiss-headquartered chemicals company’s colorants and paper solutions business, says: ‘With these first grades, we are already able to cover most colour needs for food contact applications and we are developing additional ones to fully meet every customer’s requirements.’
The company has employed an innovative dye chemistry to ensure that they do not violate stipulations in of the German BfR recommendation XXXVI, which governs the implementation of EU Directive 2002/61/EC on the use of azo-colorants.
Archroma has done this by not adding diethanolamine (DEA) and triethanolamine (TEA) – which are conventionally used to maintain storage stability – to the new Cartasol dyes. Both TEA and DEA are now under scrutiny, due to their alleged carcinogenic and mutagenic properties.
Jewell concludes: ‘As a responsible and proactive leading supplier, we have applied our specialist know-how to reformulate these dyes, aiming for the elimination of DEA and TEA, to help our customers meet the current food contact regulations.’
