Following an active research program, Archroma has developed new food compliant dye formulations in order to comply with European regulations* which have recently come into force, setting extremely low limitations for DEA and TEA contents in paper and board intended for food contact applications.
DEA and TEA have been used in the past to help maintain storage stability and prevent deposits forming over time. However, these amines are under scrutiny as they are potentially mutagenic. Potentially these dyes could be no longer considered suitable for food contact applications such as deep dyed napkins.
Archroma offers the following new grades in the range:
• Cartasol® Blue GDFC liq
• Cartasol® Yellow 2GFC liq
• Cartasol® Red 7BFC liq
• Cartasol® Blue 3RFC liq
These four new dyes extend our already extensive range of food compliant dyes, strengthening Archroma as a leading supplier of colorants for this sector.
An additional benefit to the customer resulting from these dye reformulations is that the C.O.D. (Chemical Oxygen Demand) and Nitrogen content is also reduced, helping reduce effluent treatment costs and improving the ecological performance. In addition they are REACH compliant and fulfill the requirements of most major eco labels.
